Field Detail

delegateRegistry

protected EPackage.Registry delegateRegistry

The delegate registry.

classLoaderToRegistryMap

protected static java.util.Map<java.lang.ClassLoader,EPackage.Registry> classLoaderToRegistryMap

A map from class loader to its associated registry.

Constructor Detail

EPackageRegistryImpl

public EPackageRegistryImpl()

Creates a non-delegating instance.

EPackageRegistryImpl

public EPackageRegistryImpl(EPackage.Registry delegateRegistry)

Creates a delegating instance.

Method Detail

createGlobalRegistry

public static EPackage.Registry createGlobalRegistry()

Creates the instance of the global registry. If a security manager is active, and "classLoader" permission is not granted, a secure delegator instance is created, i.e., a private registry implementation that securely accesses class loaders and keeps them private, will be used.

getEPackage

public EPackage getEPackage(java.lang.String nsURI)

Description copied from interface: EPackage.Registry

Looks up the value in the map, converting EPackage.Descriptor objects to EPackage objects on demand.

Specified by:

getEPackage in interface EPackage.Registry

getEFactory

public EFactory getEFactory(java.lang.String nsURI)

Description copied from interface: EPackage.Registry

Looks up the value in the map, converting EPackage.Descriptor objects to EFactory objects on demand.

Specified by:

getEFactory in interface EPackage.Registry

initialize

protected void initialize(EPackage ePackage)

Creates a delegating instance.

delegatedGetEPackage

protected EPackage delegatedGetEPackage(java.lang.String nsURI)

Returns the package from the delegate registry, if there is one.

Returns:

the package from the delegate registry.

delegatedGetEFactory

protected EFactory delegatedGetEFactory(java.lang.String nsURI)

Returns the factory from the delegate registry, if there is one.

Returns:

the factory from the delegate registry.

containsKey

public boolean containsKey(java.lang.Object key)

Returns whether this map or the delegate map contains this key. Note that if there is a delegate map, the result of this method may not be the same as keySet().contains(key).

Specified by:

containsKey in interface java.util.Map<java.lang.String,java.lang.Object>

Overrides:

containsKey in class java.util.HashMap<java.lang.String,java.lang.Object>

Parameters:

key - the key whose presence in this map is to be tested.

Returns:

whether this map or the delegate map contains this key.

getRegistry

public static EPackage.Registry getRegistry(java.lang.ClassLoader classLoader)

Returns the package registry associated with the given class loader.

Parameters:

classLoader - the class loader.

Returns:

the package registry associated with the given class loader.
