Class MultipleGroovyScriptFactory

java.lang.Object

com.neurosys.scribble.groovy.MultipleGroovyScriptFactory

All Implemented Interfaces:

ScriptFactory<groovy.lang.GroovyObject>, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class MultipleGroovyScriptFactory
extends Object
implements org.springframework.context.ApplicationContextAware, ScriptFactory<groovy.lang.GroovyObject>

Does not need a default script in the constructor and does not respect about the cache any created object; unlike GroovyScriptFactory

Method Detail

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext context)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException

getGroovyClassLoader

public groovy.lang.GroovyClassLoader getGroovyClassLoader()

Return the GroovyClassLoader used by this script factory.

getScriptedObject

public Object getScriptedObject(org.springframework.scripting.ScriptSource scriptSource,
                                File scriptFromFile,
                                Class[] actualInterfaces,
                                Map<String,Object> injectedParams)
                         throws IOException,
                                org.springframework.scripting.ScriptCompilationException

Loads and parses the Groovy script via the GroovyClassLoader and provide it Spring Context.
If param scriptFromFile is null then it creates a GroovyShell with the following input bindings:

• contextParams - same as injectedParams
• context - Spring Context

Specified by:

getScriptedObject in interface ScriptFactory<groovy.lang.GroovyObject>

Parameters:

ScriptSource -

scriptFromFile - as InputStream as the Script to be compiled - Can be from a File or ScriptSource.getScriptAsString() .. see GroovyClassLoader#parseClass(...) options @nullable true (Optional). if not specified then ScriptSource.getScriptAsString() will be used. This is supplied as ScriptSource.getScriptAsString() may not execute from all types of Resources

actualInterfaces - as Class[] @nullable true

injectedParams - as Params to inject into the created script instance @nullable true

Returns:

the result object (either an instance of the script class GroovyObject, or the result of running the script instance as any object)

Throws:

IOException

org.springframework.scripting.ScriptCompilationException

GroovyClassLoader

executeScript

protected Object executeScript(org.springframework.scripting.ScriptSource scriptSource,
                               Class scriptClass)
                        throws org.springframework.scripting.ScriptCompilationException

Instantiate the given Groovy script class and run it if necessary.

Parameters:

scriptSource - the source for the underlying script

scriptClass - the Groovy script class

Returns:

the result object (either an instance of the script class GroovyObject, or the result of running the script instance as any object)

Throws:

org.springframework.scripting.ScriptCompilationException - in case of instantiation failure

executeMethod

public Object executeMethod(groovy.lang.GroovyObject adapter,
                            String methodName,
                            Object... args)
                     throws Exception
