Interface ViewHandler

All Known Subinterfaces:

BERTLVEditHandler, BERTLVViewHandler, EditHandler, EnvelopeHandler, EnvelopeResponseHandler, ProactiveHandler, ProactiveResponseHandler

public interface ViewHandler

The ViewHandler class offers basic services and contains basic methods to handle a Comprehension TLV List, such as in a Terminal Response data field or in a BER-TLV element (Envelope data field or Proactive command). The byte at offset 0 of a handler is the tag of the first Comprehension TLV.

Returns:

length in bytes

Throws:

ToolkitException - with the following reason codes:

                  ToolkitException

Copies the Comprehension TLV list contained in the handler to the destination byte array.

Parameters:

dstBuffer - a reference to the destination buffer

dstOffset - the position in the destination buffer

dstLength - the data length to be copied

Returns:

dstOffset+dstLength

Throws:
