Class ReplacerAdapter

java.lang.Object

aQute.libg.reporter.ReporterAdapter

aQute.libg.sed.ReplacerAdapter

All Implemented Interfaces:

Replacer, Report, Reporter, Runnable

public class ReplacerAdapter
extends ReporterAdapter
implements Replacer

Provide a macro Domain. This Domain 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 Domain (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.
