discover
public static MapSetExecutor discover(Introspector is, java.lang.Class<?> clazz, java.lang.Object identifier, java.lang.Object value)
Attempts to discover a MapSetExecutor.- Parameters:
is
- the introspectorclazz
- the class to find the set method fromidentifier

getTargetProperty
in classAbstractExecutor
- Returns:
- the target property
-
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
public java.lang.Object tryInvoke(java.lang.Object obj, java.lang.Object key, java.lang.Object value)
Description copied from interface:JexlPropertySet
Attempts to reuse this JexlPropertySet, checking that it is compatible with the actual set of arguments.- Parameters:
obj
- the object to invoke the get uponkey
- the property key to getvalue
- the property value to set- Returns:
- the result of the method invocation that should be checked by tryFailed to determine if it succeeded or failed.
