Interface ChunkParser

public interface ChunkParser

Chunk data parser. Implementations of this interface are used by a ChunkedInput instance for parsing response entity input stream into chunks.

Chunk parsers are expected to read data from the response entity input stream until a non-empty data chunk is fully read and then return the chunk data back to the ChunkedInput instance for further processing (i.e. conversion into a specific Java type).

Chunk parsers are typically expected to skip any empty chunks (the chunks that do not contain any data) or any control meta-data associated with chunks, however it is not a hard requirement to do so. The decision depends on the knowledge of which MessageBodyReader implementation is selected for de-serialization of the chunk data.
