discover
public static ListSetExecutor discover(Introspector is, Class<?> clazz, Object identifier, Object value) Attempts to discover a ListSetExecutor.- Parameters:
is
- the introspectorclazz
- the class to find the get method fromidentifier
- the key to use as an argument to the get methodvalue
- the value to use as argument in list.put(key,value)- Returns:
- the executor if found, null otherwise
-
getTargetProperty

getTargetProperty
in classAbstractExecutor
- Returns:
- the target property
-
invoke
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
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.
