changeDataJoiner

protected RowInRecordChangeDataJoiner changeDataJoiner(Grid grid,
                                                       ChangeContext context)
                                                throws OperationException

Description copied from class: ExpressionBasedOperation

Returns the joiner used to insert the result of the evaluation of the expression into a row or record. Depending on whether the expression is local or not (see Evaluable.isLocal()), this will either be used to build a row / record mapper to apply the change lazily on the grid, or the results of the evaluation will be stored in a ChangeData object which will then be joined by this joiner.

Specified by:

changeDataJoiner in class ExpressionBasedOperation

Parameters:

grid - the initial state of the grid

Throws:

OperationException
