ListSetExecutor
public ListSetExecutor(Introspector is, java.lang.Class<?> clazz, java.lang.Integer key, java.lang.Object value)
Creates an instance checking for the List interface or Array capability.- Parameters:
is
- the introspectorclazz
- the class that might implement the map interfacekey
- the key to use in obj.set(key,value)value
- the value to use in obj.set(key,value)
-

Method Detail
-
getTargetProperty
public java.lang.Object getTargetProperty()
Gets the property targeted by this executor.- Overrides:
getTargetProperty
in classAbstractExecutor
- Returns:
- the target property
-
execute
public java.lang.Object execute(java.lang.Object obj, java.lang.Object value)
Sets the property value of an object.- Specified by:
execute
in classAbstractExecutor.Set
- Parameters:
obj
- The object to set the property in.value
- The value.- Returns:
- The return value.
-
tryExecute
public java.lang.Object tryExecute(java.lang.Object obj, java.lang.Object key, java.lang.Object value)
Tries to reuse this executor, checking that it is compatible with the actual set of arguments.Compatibility means that:
o
must be of the same class as this executor's target class,property
must be of the same class as this executor's target property (for list and map based executors) and have the same value (for other types) and thatarg
must be a valid argument for this executor underlying method.- Overrides:
tryExecute
in classAbstractExecutor.Set
- Parameters:
obj
- The object to invoke the method from.key
- The property to set in the object.value
- The value to use as the property value.- Returns:
- The return value or TRY_FAILED if checking failed.
