Interface Chunker

All Superinterfaces:

AutoCloseable, Closeable

All Known Implementing Classes:

CharReadableChunker, ClosestNewLineChunker

public interface Chunker
extends Closeable

Takes a bigger stream of data and chunks it up into smaller chunks. The chunks are allocated explicitly and are passed into #nextChunk(Chunk) to be filled/assigned with data representing next chunk from the stream. This design allows for efficient reuse of chunks when there are multiple concurrent processors, each processing chunks of data.

Method Detail

newChunk

Source.Chunk newChunk()

Returns:

a new allocated Source.Chunk which is to be later passed into #nextChunk(Chunk) to fill it with data. When a Source.Chunk has been fully processed then it can be passed into #nextChunk(Chunk) again to get more data.

nextChunk

boolean nextChunk(Source.Chunk chunk)
           throws IOException

Fills a previously allocated chunk with data to be processed after completion of this call.

Parameters:

chunk - Source.Chunk to fill with data.

Returns:

true if at least some amount of data was passed into the given Source.Chunk, otherwise false denoting the end of the stream.

Throws:

IOException - on I/O error.

position

long position()

Returns:

byte position of how much data has been returned from #nextChunk(Chunk).
