Method Detail

tokenizeToStringArray

public static String[] tokenizeToStringArray(String str,
                                             String delimiters)

Tokenize the given String into a String array via a StringTokenizer. Trims tokens and omits empty tokens.

The given delimiters string is supposed to consist of any number of delimiter characters. Each of those characters can be used to separate tokens. A delimiter is always a single character; for multi-character delimiters, consider using delimitedListToStringArray

Parameters:

str - the String to tokenize

delimiters - the delimiter characters, assembled as String (each of those characters is individually considered as delimiter).

Returns:

an array of the tokens

StringTokenizer, String.trim()

setPathSeparator

public void setPathSeparator(String pathSeparator)

Set the path separator to use for pattern parsing. Default is "/", as in Ant.

isPattern

public boolean isPattern(String path)

match

public boolean match(String pattern,
                     String path)

matchStart

public boolean matchStart(String pattern,
                          String path)

doMatch

protected boolean doMatch(String pattern,
                          String path,
                          boolean fullMatch)

Actually match the given path against the given pattern.

Parameters:

pattern - the pattern to match against

path - the path String to test

fullMatch - whether a full pattern match is required (else a pattern match as far as the given base path goes is sufficient)

Returns:

true if the supplied path matched, false if it didn't

extractPathWithinPattern

public String extractPathWithinPattern(String pattern,
                                       String path)

Given a pattern and a full path, determine the pattern-mapped part.

For example:

• '/docs/cvs/commit.html' and ' /docs/cvs/commit.html -> ''
• '/docs/*' and '/docs/cvs/commit -> ' cvs/commit'
• '/docs/cvs/*.html' and ' /docs/cvs/commit.html -> 'commit.html'
• '/docs/**' and '/docs/cvs/commit -> ' cvs/commit'
• '/docs/**\/*.html' and ' /docs/cvs/commit.html -> 'cvs/commit.html'
• '/*.html' and '/docs/cvs/commit.html -> ' docs/cvs/commit.html'
• '*.html' and '/docs/cvs/commit.html -> ' /docs/cvs/commit.html'
• '*' and '/docs/cvs/commit.html -> ' /docs/cvs/commit.html'

Assumes that match(java.lang.String, java.lang.String) returns true for ' pattern' and 'path', but does not enforce this.
