    • fetchTable

      TableRowIterator fetchTable() throws com.ebasetech.xi.exceptions.FormRuntimeException
      Loads data into the table from the external resource specified as the backing resource, and sets the first row as the current row (see getCurrentRow()). All internal row numbers are reset.

      Further documentation.

      Javascript example: 

       var orders = tables.ORDERS;
 var rows = orders.fetchTable();
 while (rows.next())
 {
   orders.ORDER_VAT.value = orders.ORDER_VALUE.value * vatRate;
 }
      Returns:
      a row iterator object that can be used to traverse all table rows
      Throws:

    • fetchTable

      TableRowIterator fetchTable​(boolean noUpdate) throws com.ebasetech.xi.exceptions.FormRuntimeException
      Loads data into the table from the external resource specified as the backing resource, and sets the first row as the current row (see getCurrentRow()). All internal row numbers are reset.

      The noUpdate flag provides an optional optimization. When this flag is set to true, the amount of memory required to support the table content data is reduced by about 50%; however, it is not possible to use the updateTable() method. It is recommended that this option should be used for all read only tables.

      Further documentation.

      Javascript example: 

       var orders = tables.ORDERS;
 var rows = orders.fetchTable(true);
 while (rows.next())
 {
   orders.ORDER_VAT.value = orders.ORDER_VALUE.value * vatRate;
 }
      Parameters:
      noUpdate - when true indicates that the table will not be updated with updateTable()
      Returns:
      a row iterator object that can be used to traverse all table rows

    • replaceTable

      void replaceTable​(Table fromTable) throws com.ebasetech.xi.exceptions.FormRuntimeException
      Removes all existing rows and copies rows from the table specified by fromTable. This method is equivalent to calling copyTable(fromTable, true). Rows flagged as empty in fromTable are ignored. Any rows in fromTable that have been deleted using the deleteRow() method are ignored. All other rows are copied.

      All columns having the same name in each table are copied e.g. if T1 has columns A, B, C, D and T2 has columns B, C, X, Y, T1.replaceTable(T2) will result in data from columns B and C being copied. Any other columns in T1 will be set to null or the column's default value. The current row (see getCurrentRow()) is set to the first row after the copy.

      The table specified by fromTable is unaffected and is not changed in any way.

      Further documentation.

      Javascript example: 

       tables.ORDERS.replaceTable(tables.ORDERS_SAVE);
      Parameters:
      fromTable - the source table from which rows are copied

      void copyTable​(Table fromTable, boolean removeExistingRows) throws com.ebasetech.xi.exceptions.FormRuntimeException
      Optionally removes all existing rows and then copies rows from the table specified by fromTable. Rows flagged as empty in fromTable are ignored. Any rows in fromTable that have been deleted using the deleteRow() method are ignored. All other rows are copied.

      All columns having the same name in each table are copied e.g. if T1 has columns A, B, C, D and T2 has columns B, C, X, Y, T1.copyTable(T2, true) will result in data from columns B and C being copied. Any other columns in T1 will be set to null or the column's default value. The current row (see getCurrentRow()) is set to the first row after the copy.

      The table specified by fromTable is unaffected and is not changed in any way.

    • resetTable

      void resetTable()
      Removes all rows from the table and resets the current row (see getCurrentRow()).

      Further documentation.

      Javascript example: 

       tables.ORDERS.resetTable();
      Note that resetTable() will not result in the deletion of records from a backing resource specified for the table e.g. a Database Resource. i.e. any subsequent updateTable() method will not remove these rows from the attached resource. To remove all rows from the table and the backing resource use: 
       var t1 = tables.MyTable;
 var rows = t1.rows;
 while (rows.next())
 {
   t1.deleteRow();
 }
 t1.updateTable();

      Returns the first row number with the specified column value, or -1 if no match is found.

      Javascript example: 

       var row = tables.ORDERS.findRow(tables.ORDERS.ORDER_ID, fields.SEARCH_ORDER_ID.value);
 if (row != -1)
 {
   tables.ORDERS.setCurrentRow(row);
 }
      Parameters:
      column - table column
      value - the value of the table column, should be the same type as the underlying column object (see Field.getValue())
      Returns:
      the row number of the found row or -1
      Since:
      V4.4
      See Also:
      findRows(Map)

    • findRows

      TableRowIterator findRows​(java.util.Map<java.lang.String,​java.lang.Object> parms)
      Returns a row iterator object containing all rows that match the search criteria specified by parms.

      Javascript example: 

       var searchParms = {};
 searchParms.CUSTOMER_TYPE = "Internal";
 searchParms.RATING = 4;
 var rows = tables.CUSTOMERS.findRows(searchParms);
 while (rows.next())
 {
   ..
 }
      Parameters:
      parms - a Map of key/value pairs where key is a column name and value is the corresponding value. In Javascript, an Object can be used where key is a column name and value is the corresponding value which should be the same type as the underlying column object (see Field.getValue()).
      Returns:
      a table row iterator
      Since:
      V4.4
      See Also:
      findRow(TableColumn, Object)

    • getCurrentRow

      int getCurrentRow()
      Returns the row number for the table's current row.

      The current row represents an important concept - a current row exists for all tables that are not empty. All references to table columns and their values which do not explicitly specify a row number are interpreted as referring to the corresponding table cell for the column on the current row. For example, in the following line of code, values for the ORDER_VAT and ORDER_VALUE columns are obtained from the current row. 

       orders.ORDER_VAT.value = orders.ORDER_VALUE.value * vatRate;
      The current row is set by the system as follows:
      • when a table cell event is executed e.g. user clicks a button or hyperlink, the current row is set to the row containing that table cell
      • while traversing table rows using a TableRowIterator, the current row is set each time the next() or previous() method is invoked. When all rows have been processed by the TableRowIterator, the current row is returned to its original value. If all rows are not processed by the TableRowIterator, the current row remains set to the row at the break point.
      • the insertRow() method, or the user clicking the add row button, both set the current row to the new row
      • the fetchTable() method sets the first row as the current row
      • a sort operation, either invoked by the user or using one of the sort(TableColumn) methods, sets the first row as the current row
      • the updateTable() may reset the current row depending on circumstances
      • a vertical scroll operation by the user sets the current row to the first visible row of the new display
      Returns:
      the row number of the table's current row
      Since:
      V4.4

    • setCurrentRow

      void setCurrentRow​(int row)
      Sets the table's current row.
      Since:
      V4.4
      See Also:
      getCurrentRow()

    • sort

      void sort​(TableColumn[] columns, java.lang.String[] directions)
      Sorts the table rows using multiple columns. Columns are processed from left to right.

      Javascript example: 

       tables.ORDERS.sort( [tables.ORDERS.DELIVERY_DATE, tables.ORDERS.QUANTITY], 
 [Table.SORT_DIRECTION_DESCENDING, Table.SORT_DIRECTION_ASCENDING] );
      Parameters:
      columns - an array of table columns
      directions - an array of directions where each direction is either "asc" or "desc" (static constants Table.SORT_DIRECTION_ASCENDING or Table.SORT_DIRECTION_DESCENDING can be used).

    • getSortColumns

      TableColumn[] getSortColumns()
      Returns an Array of all the columns that are currently sorted. This can be useful to reestablish a sort order created by the user after a fetchtable.

      See getSortDirections() for documentation on sort directions
      See sort(TableColumn[]) for documentation on sorting columns

      Javascript examples: 

       var sortColumns = tables.ORDERS.getSortColumns();

      See Also:
      getSortDirections(), sort(TableColumn[], String[])

    • getSortDirections

      java.lang.String[] getSortDirections()
      Returns an Array of all the directions that are currently sorted. The position of the sort in the Array matches the position of the column name within the Array returned from getSortColumns(). This can be useful to reestablish a sort order created by the user after a fetchtable.

      The sort order directions are defined as SORT_DIRECTION_ASCENDING or SORT_DIRECTION_DESCENDING.

      See getSortDirections() for documentation on sort directions
      See sort(TableColumn[], String[]) for documentation on sorting columns

      Javascript examples: 

       var sortColumns = tables.ORDERS.getSortColumns();
 var sortDirections = tables.ORDERS.getSortDirections();
 tables.ORDERS.fetchTable();
 tables.ORDERS.sort(sortColumns, sortDirections);

    • toJSON

      java.lang.String toJSON()
      Returns a JSON string representing all rows in the table in the following format: 
       {
  rows:
   [
    {Name:Smith, Age:31, StartDate:1459206000000},
    {Name:Mendez, Age:23, StartDate:1462306000000},
    {Name:Jones, Age:45, StartDate:1459961000000}
   ]
 }
      The JSON string contains a single "rows" property which contains an array of table rows where each row contains columnName:value property pairs where the value for each column is the same as its value property, see Field.getValue(). Columns with null values are included with an explicit "null" value. See toJSON(boolean) which includes an option to exclude columns with a null value.

      Examples: 

       // 1. send to REST web service
 var ordersJson = tables.ORDERS.toJSON();
 services.rest.put("http://example.com/rest/orders", ordersJson);
 // 2. convert to Javascript object
 var ordersJson = tables.ORDERS.toJSON();
 var ordersObj = JSON.parse(ordersJson);
 var order1Value = ordersObj.rows[0].orderValue;
 var order2Id = ordersObj.rows[1].orderId;
 for each (var order in ordersObj.rows)
 {
   var id = order.orderId;
   var orderDate = order.orderDate;
 }
      Since:
      V5.1
      See Also:
      toJSON(boolean), loadFromJSON(String)

    • toJSON

      java.lang.String toJSON​(boolean excludeNullValues)
      Returns a JSON string representing all rows in the table, this is the same as toJSON() but additionally provides an option on how null values in table columns are handled. Columns with a null value can either be omitted or included as value "null". 
       {
  rows:
   [
    {Name:Smith, Age:31, StartDate:1459206000000},
    {Name:Mendez, Age:23, StartDate:1462306000000},
    {Name:Jones, Age:null, StartDate:null}
   ]
 }
      The JSON string contains a single "rows" property which contains an array of table rows where each row contains columnName:value property pairs where the value for each column is the same as its value property, see Field.getValue(). when excludeNullValues is true, columns with null values are omitted. When excludeNullValues is false, columns with null values are included with value "null" - see example above;

      Examples: 

       // 1. send to REST web service
 var ordersJson = tables.ORDERS.toJSON(true);
 services.rest.put("http://example.com/rest/orders", ordersJson);
 // 2. convert to Javascript object
 var ordersJson = tables.ORDERS.toJSON(true);
 var ordersObj = JSON.parse(ordersJson);
 var order1Value = ordersObj.rows[0].orderValue;
 var order2Id = ordersObj.rows[1].orderId;
 for each (var order in ordersObj.rows)
 {
   var id = order.orderId;
   var orderDate = order.orderDate;
 }
      Parameters:
      excludeNullValues - when true, columns with null values are omitted; when false, columns with null values are included with value "null"

      toJSON(), loadFromJSON(String)

    • loadFromJSON

      void loadFromJSON​(java.lang.String jsonString)
      Loads rows from a JSON string into the table. The JSON string must be formatted as per the following example (which is split into multiple rows for clarity): 
       "{
  rows:
   [
    {Name:Smith, Age:31, StartDate:1459206000000},
    {Name:Mendez, Age:23, StartDate:1462306000000},
    {Name:Jones, Age:45, StartDate: null}
   ]
 }"
      This represents a Javascript object with a single "rows" property which contains an array of table rows where each row contains columnName:value property pairs. Any value that can be specified for a column's value property can be used, see Field.setValue(Object). Columns with null values can be either excluded completely or "null" can be specified as the column value as per the example above. The toJSON() methods can be used to generate a JSON string with this format from an existing table.

      This method does not delete any existing rows that might exist in the table. If this is required resetTable() should be called first.

      Examples: 

       var jsonString = "{rows:[{Name:Smith, Age:31, StartDate:1459206000000}, {Name:Mendez, Age:23, StartDate:1462306000000}]}"  
 tables.ORDERS.loadFromJSON(jsonString);
 tables.ORDERS.control.scrollToTop();             //scroll to the top of the table
      Parameters:
      jsonString - formatted JSON string containing table row data
