Constructor Details

ChannelMapper

public ChannelMapper(IntFunction<Channel> channelGetter,
 IntFunction<Optional<ChannelConverterAttached<Channel,UnsignedByteBuffer>>> converterGetter)

Creates a new ChannelMapper instance.

Parameters:

channelGetter - Gets a Channel corresponding to a particular index (zero-indexed).

converterGetter - Gets a converter corresponding to a channel at a particular index (zero-indexed).

Method Details

mapChannelIfSupported

public <T> T mapChannelIfSupported(int channelIndex,
 BiFunction<Channel,ChannelConverterAttached<Channel,UnsignedByteBuffer>,T> mapFunction,
 Function<Channel,T> fallback)

Maps a Channel with mapFunction if a corresponding converter exists, otherwise with fallback.

Type Parameters:

T - the destination type to map to.

Parameters:

channelIndex - the index of the channel to map, as well as the corresponding converter.

mapFunction - used for the mapping, if a corresponding converter for channelIndex exists.

fallback - used for the mapping, if a corresponding converter for channelIndex does not exist.

Returns:

the result of the mapping.

consumeChannelIfSupported

public void consumeChannelIfSupported(int channelIndex,
 BiConsumer<Channel,ChannelConverterAttached<Channel,UnsignedByteBuffer>> consumer,
 Consumer<Channel> fallback)

Like mapChannelIfSupported(int, BiFunction, Function) but the mapping has no return-type.

Parameters:

channelIndex - the index of the channel to consume, as well as the corresponding converter.

consumer - used for the consuming, if a corresponding converter for channelIndex exists.

fallback - used for the consuming, if a corresponding converter for channelIndex does not exist.
