Field Detail

protocolToFactoryMap

protected Map protocolToFactoryMap
The protocol map.


extensionToFactoryMap

protected Map extensionToFactoryMap
The extension map.

Constructor Detail

ResourceFactoryRegistryImpl

public ResourceFactoryRegistryImpl()
Creates an instance.

Method Detail

getFactory

public Resource.Factory getFactory(URI uri)
Returns the resource factory appropriate for the given URI.

This implementation does the typical thing. It will delegate to delegatedGetFactory(URI) in the case that the typical behaviour doesn't produce a result; clients are encouraged to override that method only.

Specified by:
getFactory in interface Resource.Factory.Registry
Parameters:
uri - the URI.
Returns:
the resource factory appropriate for the given URI.
See Also:
ResourceSet.createResource(URI)

delegatedGetFactory

protected Resource.Factory delegatedGetFactory(URI uri)
Returns the resource factory appropriate for the given URI, when standard alternatives fail.

This implementation returns null; clients are encouraged to override it.

Parameters:
uri - the URI.
Returns:
the resource factory appropriate for the given URI.
See Also:
getFactory(URI)

getExtensionToFactoryMap

public Map getExtensionToFactoryMap()
Description copied from interface: Resource.Factory.Registry
Returns a map from file extension to Resource.Factory or Resource.Factory.Descriptor.

The default file extension "*" can be registered as a default that matches any file extension. This is typically reserved for a default factory that supports XMI serialization; clients are strongly discouraged from using this feature in the global registry, particularly those that must function effectively within an Eclipse environment.

Specified by:
getExtensionToFactoryMap in interface Resource.Factory.Registry
Returns:
the file extension map.
See Also:
Resource.Factory.Registry.DEFAULT_EXTENSION

getProtocolToFactoryMap

public Map getProtocolToFactoryMap()
Description copied from interface: Resource.Factory.Registry
Returns a map from protocol to Resource.Factory or Resource.Factory.Descriptor.

Specified by:
getProtocolToFactoryMap in interface Resource.Factory.Registry
Returns:
the protocol map.
