Class Summary |
| Matcher |
Matcher instance is an automaton that actually performs matching. |
| Optimizer |
|
| Pattern |
A handle for a precompiled regular expression.
To match a regular expression myExpr against a text myString one should first create a Pattern object:
Pattern p=new Pattern(myExpr);
then obtain a Matcher object:
Matcher matcher=p.matcher(myText);
The latter is an automaton that actually performs a search. |
| PerlSubstitution |
An implementation of the Substitution interface. |
| Replacer |
The Replacer class suggests some methods to replace occurences of a pattern
either by a result of evaluation of a perl-like expression, or by a plain string,
or according to a custom substitution model, provided as a Substitution interface implementation.
A Replacer instance may be obtained either using Pattern.replacer(...) method, or by constructor:
Pattern p=new Pattern("\\w+");
Replacer perlExpressionReplacer=p.replacer("[$&]");
//or another way to do the same
Substitution myOwnModel=new Substitution(){
public void appendSubstitution(MatchResult match,TextBuffer tb){
tb.append('[');
match.getGroup(MatchResult.MATCH,tb);
tb.append(']');
}
}
Replacer myVeryOwnReplacer=new Replacer(p,myOwnModel);
The second method is much more verbose, but gives more freedom.

| RETokenizer |
The Tokenizer class suggests a methods to break a text into tokens using
occurences of a pattern as delimiters.

| WildcardPattern |
Simpified, command-prompt style pattern:
