Method Detail

computeNewValueForLeftOperand

public Object computeNewValueForLeftOperand(SOperation operation,
                                            Object value,
                                            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

Parameters:

operation - the operation in progress

value - 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

public String getOperationType()

Specified by:

getOperationType in interface OperationExecutorStrategy

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

Returns:

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