Field Detail

text

protected final java.util.List text

The text to be printed. Since the code of methods is not necessarily visited in sequential order, one method after the other, but can be interlaced (some instructions from method one, then some instructions from method two, then some instructions from method one again...), it is not possible to print the visited instructions directly to a sequential stream. A class is therefore printed in a two steps process: a string tree is constructed during the visit, and printed to a sequential stream at the end of the visit. This string tree is stored in this field, as a string list that can contain other string lists, which can themselves contain other string lists, and so on.

buf

protected final java.lang.StringBuffer buf

A buffer that can be used to create strings.

pw

protected final java.io.PrintWriter pw

The print writer to be used to print the class.
