Interface Resource<Z>

Type Parameters:

Z - The type of resource wrapped by this class.

All Known Implementing Classes:

BitmapDrawableResource, BitmapResource, BytesResource, EngineResource, FileResource, GifBitmapWrapperResource, GifDrawableResource, GlideBitmapDrawableResource

public interface Resource<Z>

A resource interface that wraps a particular type so that it can be pooled and reused.

Method Summary

Z	get() Returns an instance of the wrapped resource.
int	getSize() Returns the size in bytes of the wrapped resource to use to determine how much of the memory cache this resource uses.
void	recycle() A method that can be used to clean up or reuse inner resources when this resource is about to be destroyed.

Method Detail

get

Z get()

Returns an instance of the wrapped resource.

Note - This does not have to be the same instance of the wrapped resource class and in fact it is often appropriate to return a new instance for each call. For example, Drawables should only be used by a single View at a time so each call to this method for Resources that wrap Drawables should always return a new Drawable.

getSize

int getSize()

Returns the size in bytes of the wrapped resource to use to determine how much of the memory cache this resource uses.

recycle

void recycle()

A method that can be used to clean up or reuse inner resources when this resource is about to be destroyed.

Must not be called directly and otherwise is guaranteed to only be called at most once. May also never be called.
