Returns a map of input channels accepting the input data identified by the specified indexes.
Note that the returned channels must be closed in order to ensure the completion of the invocation lifecycle.

Type Parameters:

DATA - the channel data type.

IN - the input data type.

Parameters:

channel - the selectable channel.

indexes - the collection of indexes.

Returns:

the map of indexes and output channels.

Returns a map of input channels accepting the input data identified by the specified indexes.
Note that the returned channels must be closed in order to ensure the completion of the invocation lifecycle.

Type Parameters:

DATA - the channel data type.

IN - the input data type.

Parameters:

channel - the selectable channel.

indexes - the array of indexes.

Returns:

the map of indexes and output channels.

mapParcelable

@Nonnull
public static <DATA,IN extends DATA> SparseArrayCompat<TransportChannel<IN>> mapParcelable(int startIndex,
                                                                                   int rangeSize,
                                                                                   @Nonnull

Returns a map of input channels accepting the input data identified by the specified indexes.
Note that the returned channels must be closed in order to ensure the completion of the invocation lifecycle.

Type Parameters:

DATA - the channel data type.

IN - the input data type.

Parameters:

startIndex - the selectable start index.

rangeSize - the size of the range of indexes (must be positive).

channel - the selectable channel.

Returns:

the map of indexes and output channels.

Throws:

IllegalArgumentException - if the specified range size is negative or 0.

mergeParcelable

@Nonnull
public static <OUT> OutputChannel<? extends Channels.ParcelableSelectable<OUT>> mergeParcelable(@Nonnull
                                                                                        SparseArrayCompat<? extends OutputChannel<? extends OUT>> channelMap)

Merges the specified channels into a selectable one.

Note that the channels will be bound as a result of the call.

Type Parameters:

OUT - the output data type.

Parameters:

channelMap - the map of indexes and output channels.

Returns:

the selectable output channel.

Throws:

IllegalArgumentException - if the specified map is empty.
