Class FamilyVersionPreprocessor

java.lang.Object
  FamilyVersionPreprocessor

All Implemented Interfaces:

SnacPreprocessor

public final class FamilyVersionPreprocessor

extends java.lang.Object

implements SnacPreprocessor

A SNAC preprocessor to filter out some recent strangeness in the protocol. If a certain SSI (family 0x13) SNAC family version is sent, the server begins certain packets with a TLV block containing that family version. Don't ask me why. Either way, I think the AOL developers might have some sympathy for third-party developers, because a 0x80 bit mask is applied to the SNAC's first "flag" byte when this TLV block has been prepended to a packet. This makes filtering it out very easy.
