Class ByteArrayLoader<Data>

java.lang.Object

com.bumptech.glide.load.model.ByteArrayLoader<Data>

Type Parameters:

Data - The type of data that will be loaded from a given byte array.

All Implemented Interfaces:

ModelLoader<byte[],Data>

public class ByteArrayLoader<Data>
extends java.lang.Object
implements ModelLoader<byte[],Data>

A base class to convert byte arrays to input streams so they can be decoded. This class is abstract because there is no simple/quick way to generate an id from the bytes themselves, so subclass must include an id.

buildLoadData

public ModelLoader.LoadData<Data> buildLoadData(@NonNull
                                                byte[] model,
                                                int width,
                                                int height,

                                                Options options)

Description copied from interface: ModelLoader

Returns a ModelLoader.LoadData containing a DataFetcher required to decode the resource represented by this model, as well as a set of Keys that identify the data loaded by the DataFetcher as well as an optional list of alternate keys from which equivalent data can be loaded. The DataFetcher will not be used if the resource is already cached.

Note - If no valid data fetcher can be returned (for example if a model has a null URL), then it is acceptable to return a null data fetcher from this method.

Specified by:

buildLoadData in interface ModelLoader<byte[],Data>

Parameters:

model - The model representing the resource.

width - The width in pixels of the view or target the resource will be loaded into, or Target.SIZE_ORIGINAL to indicate that the resource should be loaded at its original width.

height - The height in pixels of the view or target the resource will be loaded into, or Target.SIZE_ORIGINAL to indicate that the resource should be loaded at its original height.

handles

public boolean handles(@NonNull
                       byte[] model)

Description copied from interface: ModelLoader

Returns true if the given model is a of a recognized type that this loader can probably load.

For example, you may want multiple Uri -> InputStream loaders. One might handle media store Uris, another might handle asset Uris, and a third might handle file Uris etc.

This method is generally expected to do no I/O and complete quickly, so best effort results are acceptable. ModelLoaders that return true from this method may return null from ModelLoader.buildLoadData(Object, int, int, Options)

Specified by:

handles in interface ModelLoader<byte[],Data>
