ModelLoader

A factory interface for translating an arbitrarily complex data model into a concrete data type that can be used by an DataFetcher to obtain the data for a resource represented by the model.

This interface has two objectives: 1. To translate a specific model into a data type that can be decoded into a resource.

2. To allow a model to be combined with the dimensions of the view to fetch a resource of a specific size.

This not only avoids having to duplicate dimensions in xml and in your code in order to determine the size of a view on devices with different densities, but also allows you to use layout weights or otherwise programmatically put the dimensions of the view without forcing you to fetch a generic resource size.

The smaller the resource you fetch, the less bandwidth and battery life you use, and the lower your memory footprint per resource.

Parameters

<Model>

The type of the model.

<Data>

The type of the data that can be used by a to decode a resource.

Types

LoadData

open class LoadData<Data>

Contains a set of Keys identifying the source of the load, alternate cache keys pointing to equivalent data, and a that can be used to fetch data not found in cache.

Functions

buildLoadData

abstract fun buildLoadData( model: Model, width: Int, height: Int, options: Options): ModelLoader.LoadData<Data>

Returns a com.bumptech.glide.load.model.ModelLoader.LoadData containing a required to decode the resource represented by this model, as well as a set of Keys that identify the data loaded by the com.bumptech.glide.load.data.DataFetcher as well as an optional list of alternate keys from which equivalent data can be loaded.
