Method Detail

computeNewValueForLeftOperand

java.lang.Object computeNewValueForLeftOperand(SOperation operation,
                                               java.lang.Object rightOperandValue,
                                               SExpressionContext expressionContext,
                                               boolean shouldPersistValue)
                                        throws SOperationExecutionException

Calculates the new value of the left operand base of right operand expression value

Parameters:

operation - the operation in progress

rightOperandValue - result of the evaluation of right operand expression

expressionContext - the expression context

shouldPersistValue - true if the right operand must be persisted (Business Data)

Returns:

the new value to set the left operand with

Throws:

SOperationExecutionException

getOperationType

java.lang.String getOperationType()

shouldPersistOnNullValue

boolean shouldPersistOnNullValue()

Determines if the operation right value should be persisted when the value is evaluated to null.

Returns:

true if the the evaluated right value should be persisted; false otherwise.
