Method Detail

computeNewValueForLeftOperand

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

Description copied from interface: OperationExecutorStrategy

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

Specified by:

computeNewValueForLeftOperand in interface OperationExecutorStrategy

Overrides:

computeNewValueForLeftOperand in class JavaMethodOperationExecutorStrategy

Parameters:

operation - the operation in progress

valueToSetObjectWith - 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

computeJavaOperation

protected java.lang.Object computeJavaOperation(SOperation operation,
                                                java.lang.Object valueToSetObjectWith,
                                                SExpressionContext expressionContext,
                                                boolean shouldPersistValue)
                                         throws SOperationExecutionException

Throws:

SOperationExecutionException

shouldPersistOnNullValue

public boolean shouldPersistOnNullValue()

Description copied from interface: OperationExecutorStrategy

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

Specified by:

shouldPersistOnNullValue in interface OperationExecutorStrategy

Overrides:

shouldPersistOnNullValue in class JavaMethodOperationExecutorStrategy

Returns:

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