Class LazyHeaders.Builder

java.lang.Object

com.bumptech.glide.load.model.LazyHeaders.Builder

Enclosing class:

LazyHeaders

public static final class LazyHeaders.Builder
extends Object

Adds an LazyHeaderFactory that will be used to construct a value for the given key* lazily on a background thread.

This class is not thread safe.

This class may include default values for User-Agent and Accept-Encoding headers. These will be replaced by calls to either setHeader(String, LazyHeaderFactory) or addHeader(String, String), even though addHeader(String, LazyHeaderFactory) would usually append an additional value.

Method Details

addHeader

public LazyHeaders.Builder addHeader(@NonNull
 String key,
 @NonNull
 String value)

Adds a value for the given header and returns this builder.

Use addHeader(String, LazyHeaderFactory) if obtaining the value requires I/O (i.e. an OAuth token).

• addHeader(String, LazyHeaderFactory)

addHeader

public LazyHeaders.Builder addHeader(@NonNull
 String key,
 @NonNull
 LazyHeaderFactory factory)

Adds an LazyHeaderFactory that will be used to construct a value for the given key lazily on a background thread.

Headers may have multiple values whose order is defined by the order in which this method is called.

This class does not prevent you from adding the same value to a given key multiple times

setHeader

public LazyHeaders.Builder setHeader(@NonNull
 String key,
 @Nullable
 String value)

Replaces all existing LazyHeaderFactorys for the given key with the given LazyHeaderFactory.

If the given value is null, the header at the given key will be removed.

Use setHeader(String, LazyHeaderFactory) if obtaining the value requires I/O (i.e. an OAuth token).

setHeader

public LazyHeaders.Builder setHeader(@NonNull
 String key,
 @Nullable
 LazyHeaderFactory factory)

Replaces all existing LazyHeaderFactorys for the given key with the given LazyHeaderFactory.

If the given value is null, the header at the given key will be removed.

build

public LazyHeaders build()

Returns a new immutable LazyHeaders object.
