RegEx

public RegEx(String pattern)

Creates and store a new Pattern, calling Pattern.compile(String)

RegEx

public RegEx(String pattern,
 int flags)

Creates and store a new Pattern, calling Pattern.compile(String, int)

Method Details

matcher

public Matcher matcher(CharSequence input)

Gets a new matcher for the input sequence

groups

public String[] groups(CharSequence input)

Returns all the groups in the input, see Java documentation for details

matches

public boolean matches(CharSequence input)

Calls matcher(input).Matcher.matches()

matchesAny

public boolean matchesAny(CharSequence... inputs)

Matches multiple strings. TODO: tests

matchesAny

public <C extends Collection<? extends CharSequence>>
boolean matchesAny(C inputs)

Matches multiple strings. TODO: tests

getPattern

public String getPattern()

matchesAny

public static boolean matchesAny(String target,
 Pattern... patterns)

Matches the string against any of the patterns, returns true at the first pattern that matches

toString

public String toString()

Overrides:

toString in class Object

of

public static RegEx of(String pattern,
 int flags)

This returns a RegEx that is cached, together with its compiled pattern. Caching is a very good idea when you need to reuse the same pattern many times, since compiling RE patterns is rather time-consuming.
