Class RegexPlaceholderMatcher

java.lang.Object

com.winterhavenmc.library.messagebuilder.adapters.pipeline.matchers.RegexPlaceholderMatcher

All Implemented Interfaces:

PlaceholderMatcher

public class RegexPlaceholderMatcher
extends Object
implements PlaceholderMatcher

Default implementation of the PlaceholderMatcher interface that uses Java’s built-in Pattern and MatchResult APIs to extract macro keys from an input string.

This class transforms matching groups into ValidMacroKey instances using MacroKey.of(...), and silently skips any invalid results.

It is designed for use in both the resolution and replacement stages of the pipeline, depending on whether base keys or full macro keys are being matched.
