Examples of bytecodeparser.analysis.stack.TrackableArray

bytecodeparser.analysis.stack.TrackableArray
A trackable Array is an array of known elements at compile time: its content can be "guessed" by the analyzer. When this array gets updated with a value that is unknown at compile-time, this value is an instance of WhateverElement. This is particularly useful to guess the names of the varargs, for example. If a trackable array contains some elements that cannot be guessed @author Stephane Godbillon
