Method Detail

create

Resource create(ResourceManager manager,
                ResourceData data,
                ResourceKey context)
                throws ResourceCreationException,
                       ResourceLoadingException
Creates a resource by interpreting the data given in the resource-data object. If additional datastreams need to be parsed, the provided resource manager should be used.

Parameters:
manager - the resource manager used for all resource loading.
data - the resource-data from where the binary data is read.
context - the resource context used to resolve relative resource paths.
Returns:
the parsed result, never null.
Throws:
ResourceCreationException - if the resource could not be parsed due to syntaxctial or logical errors in the data.
ResourceLoadingException - if the resource could not be accessed from the physical storage.

getFactoryType

Class getFactoryType()
Returns the expected result type.

Returns:
the result type.

initializeDefaults

void initializeDefaults()
Initializes the resource factory. This usually loads all system resources from the environment and maybe sets up and initializes any factories needed during the parsing.
