com.fasterxml.util.membuf.ChunkyBytesMemBuffer.readNextEntry()

Method for reading and removing next available entry from buffer and return length of the entry in bytes, if succesful; or, if buffer does not have enough space, return negative number as error code. If no entry is available, will block to wait for more data. @param buffer Buffer in which entry is to be read: must have enough spacefor read to succeed @param offset Offset in buffer to use for storing results @return Length of the entry (non-negative) if read succeeds;or, negative number that indicates length of the entry in case of failures: for example, if buffer only had space for 4 bytes, and entry length was 6, would return -6.


       chunk = buffer.peekNextEntry();
       Assert.assertArrayEquals(buildBytesChunk(6), chunk);
       assertEquals(6, buffer.getNextEntryLength());
       byte[] buf = new byte[6];
       assertEquals(6, buffer.readNextEntry(buf, 0));
       Assert.assertArrayEquals(chunk, buf);


       // and when empty, nothing more:
       assertEquals(-1, buffer.skipNextEntry());
       assertTrue(buffer.isEmpty());
