Class ProxyModuleDefinition

java.lang.Object
  com.sun.enterprise.module.single.ProxyModuleDefinition

All Implemented Interfaces:

ModuleDefinition

public class ProxyModuleDefinition
extends Object
implements ModuleDefinition

Creates a ModuleDefinition backed up by a a single classloader.

The implementation does not cache any data - everything is recalculated for each call. Callers are therefore encouraged to either supply their own caching, or minimize the calls to methods of this class.

Method Detail

getName

public String getName()

Description copied from interface: ModuleDefinition

Returns the module name, usually this is the same name as the jar file name containing the module's implementation.

Specified by:

getName in interface ModuleDefinition

Returns:

module name

getPublicInterfaces

public String[] getPublicInterfaces()

Description copied from interface: ModuleDefinition

Returns a list of public interfaces for this module. Public interface can be packages, interfaces, or classes

Specified by:

getPublicInterfaces in interface ModuleDefinition

Returns:

a array of public interfaces

getDependencies

public ModuleDependency[] getDependencies()

Description copied from interface: ModuleDefinition

Returns the list of this module's dependencies. Each dependency must be satisfied at run time for this module to function properly.

Specified by:

getDependencies in interface ModuleDefinition

Returns:

list of dependencies

getLocations

public URI[] getLocations()

Description copied from interface: ModuleDefinition

A Module is implemented by one to many jar files. This method returns the list of jar files implementing the module

Specified by:

getLocations in interface ModuleDefinition

Returns:

the module's list of implementation jars

getVersion

public String getVersion()

Description copied from interface: ModuleDefinition

Returns the version of this module's implementation

Specified by:

getVersion in interface ModuleDefinition

Returns:

a version number

getImportPolicyClassName

public String getImportPolicyClassName()

Description copied from interface: ModuleDefinition

Returns the import policy class name. Although the implementation of this policy does not necessary have to implement the ImportPolicy, but could use another interface, it is the responsibility of the associated Repository to invoke that interface when the module is started.

Specified by:

getImportPolicyClassName in interface ModuleDefinition

Returns:

Fully qualified class name that's assignable to ImportPolicy, or null if no import policy exists.

getLifecyclePolicyClassName

public String getLifecyclePolicyClassName()

Description copied from interface: ModuleDefinition

Returns the lifecycle policy class name. Although the implementation of this policy does not necessary have to implement the LifecyclePolicy, but could use another interface, it is the responsibility of the associated Repository to invoke that interface when the module is started.

Specified by:

getLifecyclePolicyClassName in interface ModuleDefinition

Returns:

Fully qualified class name that's assignable to LifecyclePolicy, or null if no import policy exists.

getManifest

public Manifest getManifest()

Description copied from interface: ModuleDefinition

Returns the manifest file for the main module jar file

Specified by:

getManifest in interface ModuleDefinition

Returns:

the manifest file

getMetadata

public ModuleMetadata getMetadata()

Description copied from interface: ModuleDefinition

Gets the metadata that describes various components and services in this module.

Specified by:

getMetadata in interface ModuleDefinition

Returns:

Always non-null.

generate

protected Manifest generate(ModuleMetadata metadata)
