Class ASMJobClassGenerator

java.lang.Object
  java.lang.ClassLoader
      net.sf.xworkquartz.asm.ASMJobClassGenerator

All Implemented Interfaces:

org.objectweb.asm.Constants

public class ASMJobClassGenerator

extends java.lang.ClassLoader

implements org.objectweb.asm.Constants

This class can be used to dynamically create classes which:

• implement Job,
• optionally implement StatefulJob,
• are instances of QuartzDispatcher.

The main purpose of these classes is to enable a Quartz scheduler to execute XWork actions.

Method Detail

getInstance

public static ASMJobClassGenerator getInstance()

createJobClass

public static java.lang.Class createJobClass(java.lang.String actionName,
                                             java.lang.String namespace)

Creates a job class which executes a given XWork action. The job instance will be stateless, meaning it will not implement the StatefulJob marker interface.

Parameters:

actionName - the name of the action (not null).

namespace - the namespace of the action (can be null or empty)

Returns:

a class which executes the specified action.

createJobClass

public static java.lang.Class createJobClass(java.lang.String actionName,
                                             java.lang.String namespace,
                                             boolean stateful)

Creates a job class which executes a given XWork action. Stateful jobs implement the StatefulJob marker interface.

Parameters:

actionName - the name of the action (not null).

namespace - the namespace of the action (can be null or empty)

stateful - true if job should be stateful

Returns:

a class which executes the specified action.

getClassName

protected java.lang.String getClassName(java.lang.String actionName,
                                        java.lang.String namespace,
                                        boolean stateful)
