org.eclipse.hyades.execution.local
Class EclipseExecutionComponentFactoryImpl

java.lang.Object
  org.eclipse.hyades.execution.local.ExecutionComponentFactoryImpl
      org.eclipse.hyades.execution.local.EclipseExecutionComponentFactoryImpl

All Implemented Interfaces:

IEclipseExecutionComponentFactory, IExecutionComponentFactory, IRemoteObject

public class EclipseExecutionComponentFactoryImpl

extends ExecutionComponentFactoryImpl

implements IEclipseExecutionComponentFactory

This specialization of ExecutionComponentFactoryImpl uses Eclipse IConfigurationElements instead of String classnames when registering execution components for local use. This allows the use of Eclipse classloaders, via createExecutableExtension(), so that execution components need not live in predetermined Hyades plugins.

Method Detail

getInstance

public static IExecutionComponentFactory getInstance(ISession session)

Get the component factory in this VM. Each VM has it's own factory. Each factory shares the same, well known id and provides the bootstrap for remote object instantiation.

Returns:

addExecutionComponent

public void addExecutionComponent(org.eclipse.core.runtime.IConfigurationElement configElement)
                           throws java.lang.ClassNotFoundException

This method adds registers the execution components specified by configElement. configElement is expected to have three attributes, named implClass, stubClass and skeletonClass. The implClass and StubClass will both be instantiated using createExecutableExtension(), and will thus use the Eclipse classloaders. Since the skeleton is only instantiated on the remote side, it will still use Class.forName.NewInstance().

Specified by:

addExecutionComponent in interface IEclipseExecutionComponentFactory

Parameters:

configElement - an Eclipse IConfigurationElement of the RegisteredExecutionComponentImpl schema for the execution component. the implementation class, stub, and skeleton must all have default constructors.

Throws:

java.lang.ClassNotFoundException - if the class is not available in any of the locations where it is required.

createExecutionComponentByType

public IExecutionComponent createExecutionComponentByType(java.lang.String type)

Specified by:

createExecutionComponentByType in interface IEclipseExecutionComponentFactory

Overrides:

createRemoteObjectByType

public IRemoteObject createRemoteObjectByType(java.lang.String type)

Create a remote object and return its stub.
