Parameters:

dis - The input stream from which the WPCodes will be read.

Throws:

AcePacketException - If there is a problem reading the codes.

getWPCode

public int getWPCode(int wpCodeIndex)

Gets a WPCode. This is passed a value from 1 to MAX_WPCODES and returns the code requested. Returns 0 if the index is out of range.
