public abstract class AuxvBuilder
extends Object

The build an auxiliary vector using the contents of the file /proc/PID/auxv. While this isn't a pure builder pattern, it is close enough.

Constructor Summary

protected

AuxvBuilder() Create a AuxvBuilder; can only extend.

Method Summary

abstract void	buildAuxiliary(int index, int type, long value) Called with each auxiliary vector entry.
abstract void	buildDimensions(int wordSize, boolean bigEndian, int numberElements) Called with the wordSize, byte order, and number of elements.
boolean	construct(byte[] auxv) Scan the auxiliary vector found in the AUXV byte array.
private boolean	construct(int pid)
boolean	construct(ProcessIdentifier pid) Scan the auxiliary vector found in /proc/PID/auxv building up an auxv.
