|
ResourceKey |
deserialize(ResourceKey bundleKey,
java.lang.String stringKey)
Creates a
ResourceKey based off the String representation
of the key. |
boolean |
isSupportedDeserializer(java.lang.String data)

serialized version of the ResourceKey.
|
boolean |
isSupportedKey(ResourceKey key)
Checks, whether this resource loader implementation was responsible for
creating this key.
|
ResourceData |
load(ResourceKey key)
Loads the binary data represented by this key.
|
java.lang.String |
serialize(ResourceKey bundleKey,
ResourceKey key)
Serializes the resource key to a String representation which can be recreated
using the
deserialize(ResourceKey) |
