Method Details

isSupportedKey

public boolean isSupportedKey(ResourceKey key)

Checks, whether this resource loader implementation was responsible for creating this key.

Specified by:

isSupportedKey in interface ResourceLoader

Parameters:

key -

Returns:

createKey

public ResourceKey createKey(Object value,
 Map factoryKeys)
                      throws ResourceKeyCreationException

Creates a new resource key from the given object and the factory keys.

Specified by:

createKey in interface ResourceLoader

Parameters:

value -

factoryKeys -

Returns:

the created key.

Throws:

ResourceKeyCreationException - if creating the key failed.

deriveKey

public ResourceKey deriveKey(ResourceKey parent,
 String path,
 Map factoryKeys)
                      throws ResourceKeyCreationException

Derives a new resource key from the given key. If neither a path nor new factory-keys are given, the parent key is returned.

Specified by:

deriveKey in interface ResourceLoader

Parameters:

parent - the parent

path - the derived path (can be null).

factoryKeys - the optional factory keys (can be null).

Returns:

the derived key.

Throws:

ResourceKeyCreationException - if the key cannot be derived for any reason.

toURL

public URL toURL(ResourceKey key)

Description copied from interface: ResourceLoader

Generates a URL version of the supplied ResourceKey.

Specified by:

toURL in interface ResourceLoader

Parameters:

key - the ResourceKey from which a URL will be created

Returns:

the URL representation of the ResourceKey

load

public ResourceData load(ResourceKey key)
                  throws ResourceLoadingException

Description copied from interface: ResourceLoader

Loads the binary data represented by this key.

Specified by:

load in interface ResourceLoader

Returns:

Throws:

ResourceLoadingException

serialize

public String serialize(ResourceKey bundleKey,
 ResourceKey key)
                 throws ResourceException

Creates a String version of the resource key that can be used to generate a new ResourceKey object via deserialization

Specified by:

serialize in interface ResourceLoader

Parameters:

bundleKey -

key -

Returns:

a String which is a serialized version of the ResourceKey

Throws:

ResourceException - indicates an error serializing the resource key

deserialize

public ResourceKey deserialize(ResourceKey bundleKey,
 String stringKey)
                        throws ResourceKeyCreationException

Parses the input string and returns a newly created ResourceKey based on the string data

Specified by:

deserialize in interface ResourceLoader

stringKey - the String representation of the ResourceKey @return a ResourceKey which matches the String representation

Throws:

ResourceKeyCreationException - indicates an error occurred in the creation or deserialization of the ResourceKey

isSupportedDeserializer

public boolean isSupportedDeserializer(String data)

Description copied from interface: ResourceLoader

Determines if the resource loader is capable of deserializing the serialized version of the ResourceKey.

Specified by:

isSupportedDeserializer in interface ResourceLoader

Parameters:

data - the serialized version of the resource key

Returns:

true if this ResourceLoader is capable of deserializing the serialized version of this resource key, false otherwise.
