Class Macro

java.lang.Object
  aQute.lib.osgi.Macro

All Implemented Interfaces:

Replacer

public class Macro
extends java.lang.Object
implements Replacer

Provide a macro processor. This processor can replace variables in strings based on a properties and a domain. The domain can implement functions that start with a "_" and take args[], the names of these functions are available as functions in the macro processor (without the _). Macros can nest to any depth but may not contain loops. Add POSIX macros: ${#parameter} String length. ${parameter%word} Remove smallest suffix pattern. ${parameter%%word} Remove largest suffix pattern. ${parameter#word} Remove smallest prefix pattern. ${parameter##word} Remove largest prefix pattern.
