Class ScriptExecutorFactory

java.lang.Object

org.identityconnectors.common.script.ScriptExecutorFactory

Direct Known Subclasses:

GroovyScriptExecutorFactory, JavaScriptExecutorFactory

public abstract class ScriptExecutorFactory
extends Object

Abstraction for finding script executors to allow us to invoke scripts from java.

NOTE: This is intended purely for executing java-embedable scripting languages. That is, the execution model is assumed to be same-JVM, so scripts can have side effects on objects passed to the script. This is used internally by the connector framework in its implementation of ScriptOnConnectorApiOp and should be used by connectors should they need to have a custom implementation of ScriptOnConnectorOp. This is not intended for use by connectors that implement ScriptOnResourceOp.
