Class DPTPCodec

java.lang.Object
  com.bankframe.ei.channel.codec.DPTPCodec

All Implemented Interfaces:

Codec

Direct Known Subclasses:

DPTPPaddingCodec

public class DPTPCodec
extends Object
implements Codec

This class converts DataPackets or Vectors of DataPackets to/from a compact XML representation. The aim of this class is to define a standard means of representing a DataPacket as a String. Secondly the class is designed to be lightweight and fast, therefore this class does all the xml encoding and decoding itself, it does not rely on third party XML packages such as Xerces or JAXP. This class is not as robust as fully fledged XML parsers, it can only handle the defined DataPacket xml reprensentation and it cannot handle xml strings that are not well formed.
