Class GroovyScriptFactory

java.lang.Object
  org.red5.server.script.groovy.GroovyScriptFactory

All Implemented Interfaces:

org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.scripting.ScriptFactory

public class GroovyScriptFactory
extends Object
implements org.springframework.scripting.ScriptFactory, org.springframework.beans.factory.BeanClassLoaderAware

ScriptFactory implementation for a Groovy script.

Typically used in combination with a org.springframework.scripting.support.ScriptFactoryPostProcessor; see the latter's Javadoc for a configuration example.

Since:

2.0

Constructor Summary

GroovyScriptFactory(String scriptSourceLocator)
Create a new GroovyScriptFactory for the given script source.

GroovyScriptFactory(String scriptSourceLocator, Class[] scriptInterfaces)

GroovyScriptFactory(String scriptSourceLocator, org.springframework.scripting.groovy.GroovyObjectCustomizer groovyObjectCustomizer)
Create a new GroovyScriptFactory for the given script source, specifying a strategy interface that can create a custom MetaClass to supply missing methods and otherwise change the behavior of the object.

Method Summary

protected Object	executeScript(Class scriptClass) Instantiate the given Groovy script class and run it if necessary.
Object	getScriptedObject(org.springframework.scripting.ScriptSource scriptSource, Class[] actualInterfaces) Loads and parses the Groovy script via the GroovyClassLoader.
Class	getScriptedObjectType(org.springframework.scripting.ScriptSource scriptSource)
Class[]	getScriptInterfaces() Groovy scripts determine their interfaces themselves, hence we don't need to explicitly expose interfaces here.
String	getScriptSourceLocator()
boolean	requiresConfigInterface() Groovy scripts do not need a config interface, since they expose their setters as public methods.
void	setBeanClassLoader(ClassLoader classLoader)
String	toString()

Constructor Detail

GroovyScriptFactory

public GroovyScriptFactory(String scriptSourceLocator)

Create a new GroovyScriptFactory for the given script source.

We don't need to specify script interfaces here, since a Groovy script defines its Java interfaces itself.

Parameters:

scriptSourceLocator - a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.

GroovyScriptFactory

public GroovyScriptFactory(String scriptSourceLocator,
                           org.springframework.scripting.groovy.GroovyObjectCustomizer groovyObjectCustomizer)

Create a new GroovyScriptFactory for the given script source, specifying a strategy interface that can create a custom MetaClass to supply missing methods and otherwise change the behavior of the object.

We don't need to specify script interfaces here, since a Groovy script defines its Java interfaces itself.

Parameters:

scriptSourceLocator - a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.

groovyObjectCustomizer - a customizer that can set a custom metaclass or make other changes to the GroovyObject created by this factory (may be null)

                           Class[] scriptInterfaces)

Method Detail

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

Specified by:

setBeanClassLoader in interface org.springframework.beans.factory.BeanClassLoaderAware

getScriptSourceLocator

public String getScriptSourceLocator()

Specified by:

getScriptSourceLocator in interface org.springframework.scripting.ScriptFactory

getScriptInterfaces

public Class[] getScriptInterfaces()

Groovy scripts determine their interfaces themselves, hence we don't need to explicitly expose interfaces here.

Specified by:

getScriptInterfaces in interface org.springframework.scripting.ScriptFactory

Returns:

null always

requiresConfigInterface

public boolean requiresConfigInterface()

Groovy scripts do not need a config interface, since they expose their setters as public methods.

Specified by:

requiresConfigInterface in interface org.springframework.scripting.ScriptFactory

getScriptedObject

public Object getScriptedObject(org.springframework.scripting.ScriptSource scriptSource,
                                Class[] actualInterfaces)

                                org.springframework.scripting.ScriptCompilationException

Loads and parses the Groovy script via the GroovyClassLoader.

Specified by:

getScriptedObject in interface org.springframework.scripting.ScriptFactory

Throws:

IOException

Parameters:

scriptClass - the Groovy script class

Returns:

the result object (either an instance of the script class or the result of running the script instance)
