java.lang.Object
  java.util.regex.Pattern.Node
      java.util.regex.Pattern.Loop

Direct Known Subclasses:

Pattern.LazyLoop

Enclosing class:

Pattern

static class Pattern.Loop

extends Pattern.Node

Handles the repetition count for a greedy Curly. The matchInit is called from the Prolog to save the index of where the group beginning is stored. A zero length group check occurs in the normal match but is skipped in the matchInit.
