Constructors Summary
public Jdk14RegexpMatcher() Constructor for JakartaOroRegexp

Methods Summary
protected java.util.regex.Pattern	getCompiledPattern(int options) Get a compiled representation of the regexp pattern param options the options return the compiled pattern throws BuildException on error int cOptions = getCompilerOptions(options); try { Pattern p = Pattern.compile(this.pattern, cOptions); return p; } catch (PatternSyntaxException e) { throw new BuildException(e); }
protected int	getCompilerOptions(int options) Convert the generic options to the regex compiler specific options. param options the generic options return the specific options // be strict about line separator int cOptions = Pattern.UNIX_LINES; if (RegexpUtil.hasFlag(options, MATCH_CASE_INSENSITIVE)) { cOptions |= Pattern.CASE_INSENSITIVE; } if (RegexpUtil.hasFlag(options, MATCH_MULTILINE)) { cOptions |= Pattern.MULTILINE; } if (RegexpUtil.hasFlag(options, MATCH_SINGLELINE)) { cOptions |= Pattern.DOTALL; } return cOptions;
public java.util.Vector	getGroups(java.lang.String argument) Returns a Vector of matched groups found in the argument using default options. Group 0 will be the full match, the rest are the parenthesized subexpressions . param argument the string to match against return the vector of groups throws BuildException on error return getGroups(argument, MATCH_DEFAULT);
public java.util.Vector	getGroups(java.lang.String input, int options) Returns a Vector of matched groups found in the argument. Group 0 will be the full match, the rest are the parenthesized subexpressions . param input the string to match against param options the regex options to use return the vector of groups throws BuildException on error Pattern p = getCompiledPattern(options); Matcher matcher = p.matcher(input); if (!matcher.find()) { return null; } Vector v = new Vector(); int cnt = matcher.groupCount(); for (int i = 0; i <= cnt; i++) { String match = matcher.group(i); // treat non-matching groups as empty matches if (match == null) { match = ""; } v.addElement(match); } return v;
public java.lang.String	getPattern() Get a String representation of the regexp pattern return the pattern throws BuildException on error return pattern;
public boolean	matches(java.lang.String argument) Does the given argument match the pattern using default options? param argument the string to match against return true if the pattern matches throws BuildException on error return matches(argument, MATCH_DEFAULT);
public boolean	matches(java.lang.String input, int options) Does the given argument match the pattern? param input the string to match against param options the regex options to use return true if the pattern matches throws BuildException on error try { Pattern p = getCompiledPattern(options); return p.matcher(input).find(); } catch (Exception e) { throw new BuildException(e); }
public void	setPattern(java.lang.String pattern) Set the regexp pattern from the String description. param pattern the pattern to match this.pattern = pattern;
