| GetNext(ByteBuffer) |
Returns the next frame of type 3 from the start of rawData. Procedure skips any starting bytes before starting flag (7E).
|
| GetNext(ByteBuffer, Int32) |
Returns the next frame of type 3 from the start of rawData. The terminating flag could not be returned if
multiple frames are linked together. Procedure skips any starting bytes before starting flag (7E).
|
| GetNext(ByteBuffer, Int32, String, Int32) |
Returns the next frame of type 3 from rawData, starting at index startIndex. The terminating flag could not be returned if
multiple frames are linked together. Procedure skips any starting bytes before starting flag (7E). Procedure updates startIndex to the beginning
of a next frame.
