Detailed Description

LTK LLRP Decoder class.

By way of example, this is how the CDecoder and CDecoderStream classes work. This example is for decoding a binary frame.

|_________________| Nested TLVs |________________||___________________________| Nested TLVs |_________________________________________________| Message

In the case of binary frame the references are to bytes within the buffer. Lookups are by type number.

In the case of an XML DOM tree, the references are to nodes in the DOM tre. Lookups are by string name.
