Class SelectorUtils
java.lang.Object
org.apache.tools.ant.types.selectors.SelectorUtils
This is a utility class used by selectors and DirectoryScanner. The functionality more properly belongs just to selectors, but unfortunately DirectoryScanner exposed these as protected methods. Thus we have to support any subclasses of DirectoryScanner that may access these methods.
This is a Singleton.

matchPatternStartTests whether or not a given path matches the start of a given pattern up to the first "**".This is not a general purpose test and should only be used if you can live with false positives. For example, pattern=**\aandstr=bwill yieldtrue.- Parameters:
- pattern- The pattern to match against. Must not be- null.
- str- The path to match, as a String. Must not be- null.
- Returns:
- whether or not a given path matches the start of a given pattern up to the first "**".

matchPatternStartTests whether or not a given path matches the start of a given pattern up to the first "**".This is not a general purpose test and should only be used if you can live with false positives. For example, pattern=**\aandstr=bwill yieldtrue.- Parameters:
- pattern- The pattern to match against. Must not be- null.
- str- The path to match, as a String. Must not be- null.
- isCaseSensitive- Whether or not matching should be performed case sensitively.
- Returns:
- whether or not a given path matches the start of a given pattern up to the first "**".
 
- 
matchPathTests whether or not a given path matches a given pattern. If you need to call this method multiple times with the same pattern you should rather use TokenizedPath- Parameters:
- pattern- The pattern to match against. Must not be- null.
- str- The path to match, as a String. Must not be- null.
- Returns:
- trueif the pattern matches against the string, or- falseotherwise.

matchTests whether or not a string matches against a pattern. The pattern may contain two special characters:
 '*' means zero or more characters
 '?' means one and only one character- Parameters:
- pattern- The pattern to match against. Must not be- null.
- str- The string which must be matched against the pattern. Must not be- null.
- Returns:
- trueif the string matches against the pattern, or- falseotherwise.

tokenizePathBreaks a path up into a Vector of path elements, tokenizing onFile.separator.- Parameters:
- path- Path to tokenize. Must not be- null.
- Returns:
- a Vector of path elements from the tokenized path
 
- 
tokenizePathBreaks a path up into a Vector of path elements, tokenizing on- Parameters:
- path- Path to tokenize. Must not be- null.
- separator- the separator against which to tokenize.
- Returns:
- a Vector of path elements from the tokenized path

- 
isOutOfDateReturns dependency information on these two files. If src has been modified later than target, it returns true. If target doesn't exist, it likewise returns true. Otherwise, target is newer than src and is not out of date, thus the method returns false. It also returns false if the src file doesn't even exist, since how could the target then be out of date.- Parameters:
- src- the original file
- target- the file being compared against
- granularity- the amount in milliseconds of slack we will give in determining out of dateness
- Returns:
- whether the target is out of date

Otherwise, target is newer than src and is not out of date, thus the method returns false. It also returns false if the src file doesn't even exist, since how could the target then be out of date.- Parameters:
- src- the original resource
- target- the resource being compared against
- granularity- the int amount in milliseconds of slack we will give in determining out of dateness
- Returns:
- whether the target is out of date

It also returns false if the src file doesn't even exist, since how could the target then be out of date.- Parameters:
- src- the original resource
- target- the resource being compared against
- granularity- the long amount in milliseconds of slack we will give in determining out of dateness
- Returns:
- whether the target is out of date
 
- 
removeWhitespace"Flattens" a string by removing all whitespace (space, tab, linefeed, carriage return, and formfeed). This uses StringTokenizer and the default set of tokens as documented in the single argument constructor.- Parameters:
- input- a String to remove all whitespace.
- Returns:
- a String that has had all whitespace removed.
 
- 
hasWildcardsTests if a string contains stars or question marks- Parameters:
- input- a String which one wants to test for containing wildcard
- Returns:
- true if the string contains at least a star or a question mark
 
- 
rtrimWildcardTokensremoves from a pattern all tokens to the right containing wildcards- Parameters:
- input- the input string
- Returns:
- the leftmost part of the pattern without wildcards
