Method Detail

evaluateHandleNull

public java.lang.Object evaluateHandleNull(java.lang.String expression)

Description copied from interface: ADFExpressionEvaluator

Evaluates the specified value expression against the evaluator's defaul variable resolver.

invokeMethod(String, Object[]) should be used if the expression is a method expression.

Differs from evaluate in that it is guaranteed not to throw a PropertyNotFoundException for null properties.

Specified by:

evaluateHandleNull in interface ADFExpressionEvaluator

evaluate

Specified by:

evaluateHandleNull in interface ADFExpressionEvaluator
