Method Detail

isEmptyLoadPath

public boolean isEmptyLoadPath(@Nullable
                               LoadPath<?,?,?> path)

Returns true if the given LoadPath is the signal object returned from get(Class, Class, Class) that indicates that we've previously found that there are no available paths to load the requested resources and false otherwise.

get

@Nullable
public <Data,TResource,Transcode> LoadPath<Data,TResource,Transcode> get(java.lang.Class<Data> dataClass,
                                                                                                 java.lang.Class<TResource> resourceClass,
                                                                                                 java.lang.Class<Transcode> transcodeClass)

May return NO_PATHS_SIGNAL to indicate that we've previously found that there are 0 available load paths for the requested types. Callers must check using isEmptyLoadPath(LoadPath) before using any load path returned by this method.

put

public void put(java.lang.Class<?> dataClass,
                java.lang.Class<?> resourceClass,
                java.lang.Class<?> transcodeClass,
                @Nullable
                LoadPath<?,?,?> loadPath)
