| * |
| * Implementations of this interface are used by a {@link org.glassfish.jersey.client.ChunkedInput} |
| * instance for parsing response entity input stream into chunks. |
| * <p> |
| * 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 {@link org.glassfish.jersey.client.ChunkedInput} instance for further |
| * processing (i.e. conversion into a specific Java type). |
| * </p> |
| * <p> |
| * 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 |
| * {@link javax.ws.rs.ext.MessageBodyReader} implementation is selected for de-serialization |
| * of the chunk data. |
