Class DirectoryBasedRepository

java.lang.Object

com.sun.enterprise.module.common_impl.AbstractRepositoryImpl

com.sun.enterprise.module.common_impl.DirectoryBasedRepository

All Implemented Interfaces:

Repository

public class DirectoryBasedRepository
extends AbstractRepositoryImpl

This class is a directory based repository implementation. This mean that all jar file residing a particular directory will be elligible to be added to this repository instance. Jar File will need to be compliant with the module definition spec which mean have a manifest file with the correct elements OR a separate manifest file with the same file name with a .mf extension.

Method Detail

initializeSubDirectories

private void initializeSubDirectories()

addListener

public boolean addListener(RepositoryChangeListener listener)

Description copied from class: AbstractRepositoryImpl

Add a listener to changes happening to this repository. Repository can change during the lifetime of an execution (files added/removed/changed)

Specified by:

addListener in interface Repository

Overrides:

addListener in class AbstractRepositoryImpl

Parameters:

listener - implementation listening to this repository changes

Returns:

true if the listener was added successfully

shutdown

public void shutdown()
              throws java.io.IOException

Description copied from interface: Repository

Specified by:

shutdown in interface Repository

Overrides:

shutdown in class AbstractRepositoryImpl

Throws:

java.io.IOException - if an error occur accessing the repository

loadModuleDefs

protected void loadModuleDefs(java.util.Map<ModuleId,ModuleDefinition> moduleDefs,
                              java.util.List<java.net.URI> libraries)
                       throws java.io.IOException

Description copied from class: AbstractRepositoryImpl

Called from AbstractRepositoryImpl.initialize() to load all ModuleDefinitions and libraries defintions

Specified by:

loadModuleDefs in class AbstractRepositoryImpl

Throws:

java.io.IOException

isDisabled

protected boolean isDisabled(java.io.File jar)

Checks the xyz.disabled file for xyz.jar and return true if the file exists.

directoryChanged

private void directoryChanged()
