is:Introspector

the introspector

clazz:Class<?>

the class that might implement the map interface

key:Object

the key to use as argument in map.put(key,value)

value:Object

the value to use as argument in map.put(key,value)

Doc from org.apache.commons.jexl2.internal.AbstractExecutor.Set.execute.

Sets the property value of an object.

public Object getTargetProperty()

Overrides org.apache.commons.jexl2.internal.AbstractExecutor.getTargetProperty.

Doc from org.apache.commons.jexl2.internal.AbstractExecutor.getTargetProperty.

Gets the property targeted by this executor.

Returns:Object

tryExecuteback to summary
public Object tryExecute(final Object obj, Object key, Object value)

Overrides org.apache.commons.jexl2.internal.AbstractExecutor.Set.tryExecute.

Doc from org.apache.commons.jexl2.internal.AbstractExecutor.Set.tryExecute.

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 that arg must be a valid argument for this executor underlying method.

Parameters
obj:Object

The object to invoke the method from.

key:Object

The property to set in the object.

value:Object

The value to use as the property value.

Returns:Object

The return value or TRY_FAILED if checking failed.
