-
invoke
public java.lang.Object invoke(java.lang.Object obj, java.lang.Object value)
Description copied from interface:JexlPropertySet
Method used to set the property value of an object.- Parameters:
obj
- Object on which the property setter will be called with the valuevalue
- value to be set- Returns:
- the value returned from the set operation (impl specific)
-
tryInvoke
