    public class DirectoryScanner
    extends java.lang.Object
    implements FileScanner, SelectorScanner, ResourceFactory
    Class for scanning a directory for files/directories which match certain criteria.

    These criteria consist of selectors and patterns which have been specified. With the selectors you can select which files you want to have included. Files which are not selected are excluded. With patterns you can include or exclude files based on their filename.

    The idea is simple. A given directory is recursively scanned for all files and directories. Each file/directory is matched against a set of selectors, including special support for matching against filenames with include and and exclude patterns. Only files/directories which match at least one pattern of the include pattern list or other file selector, and don't match any pattern of the exclude pattern list or fail to match against a required selector will be placed in the list of files/directories found.

    When no list of include patterns is supplied, "**" will be used, which means that everything will be matched. When no list of exclude patterns is supplied, an empty list is used, such that nothing will be excluded. When no selectors are supplied, none are applied.

    The filename pattern matching is done as follows: The name to be matched is split up in path segments. A path segment is the name of a directory or file, which is bounded by File.separator ('/' under UNIX, '\' under Windows). For example, "abc/def/ghi/xyz.java" is split up in the segments "abc", "def","ghi" and "xyz.java". The same is done for the pattern against which should be matched.

    The segments of the name and the pattern are then matched against each other. When '**' is used for a path segment in the pattern, it matches zero or more path segments of the name.

    There is a special case regarding the use of File.separators at the beginning of the pattern and the string to match:

    • When a pattern starts with a File.separator, the string to match must also start with a File.separator.
    • When a pattern does not start with a File.separator, the string to match may not start with a File.separator.
    • When one of the above rules is not obeyed, the string will not match.

    When a name path segment is matched against a pattern path segment, the following special characters can be used:
    '*' matches zero or more characters
    '?' matches one character.

    Examples:

    "**\*.class" matches all .class files/dirs in a directory tree.

    "test\a??.java" matches all files/dirs which start with an 'a', then two more characters and then ".java", in a directory called test.

    "**" matches everything in a directory tree.

    "**\test\**\XYZ*" matches all files/dirs which start with "XYZ" and where there is a parent directory called test (e.g. "abc\test\def\ghi\XYZ123").

    Case sensitivity may be turned off if necessary. By default, it is turned on.

    Example of usage:

       String[] includes = {"**\\*.class"};
       String[] excludes = {"modules\\*\\**"};
       ds.setIncludes(includes);
       ds.setExcludes(excludes);
       ds.setBasedir(new File("test"));
       ds.setCaseSensitive(true);
       ds.scan();
    
       System.out.println("FILES:");
       String[] files = ds.getIncludedFiles();
       for (int i = 0; i < files.length; i++) {
         System.out.println(files[i]);
       }
     
    This will scan a directory called test for .class files, but excludes all files in all proper subdirectories of a directory called "modules".

        setIncludes in interface FileScanner
        Parameters:
        includes - A list of include patterns. May be null, indicating that all files should be included. If a non-null list is given, all elements must be non-null.
      • setExcludes

        public void setExcludes​(java.lang.String[] excludes)
        Set the list of exclude patterns to use. All '/' and '\' characters are replaced by File.separatorChar, so the separator used need not match File.separatorChar.

        When a pattern ends with a '/' or '\', "**" is appended.

        Specified by:
        setExcludes in interface FileScanner
        Parameters:
        excludes - A list of exclude patterns. May be null, indicating that no files should be excluded. If a non-null list is given, all elements must be non-null.
      • addExcludes

        public void addExcludes​(java.lang.String[] excludes)
        Add to the list of exclude patterns to use. All '/' and '\' characters are replaced by File.separatorChar, so the separator used need not match File.separatorChar.

        When a pattern ends with a '/' or '\', "**" is appended.

        Parameters:
        excludes - A list of exclude patterns. May be null, in which case the exclude patterns don't get changed at all.
        Since:
        Ant 1.6.3
      • setSelectors

        public void setSelectors​(FileSelector[] selectors)
        Set the selectors that will select the filelist.
        Specified by:
        setSelectors in interface SelectorScanner
        Parameters:
        selectors - specifies the selectors to be invoked on a scan.
      • isEverythingIncluded

        public boolean isEverythingIncluded()
        Return whether or not the scanner has included all the files or directories it has come across so far.
        Returns:
        true if all files and directories which have been found so far have been included.
      • scan

        public void scan()
                  throws java.lang.IllegalStateException
        Scan for files which match at least one include pattern and don't match any exclude patterns. If there are selectors then the files must pass muster there, as well. Scans under basedir, if set; otherwise the include patterns without leading wildcards specify the absolute paths of the files that may be included.
        Specified by:
        scan in interface FileScanner
        Throws:
        java.lang.IllegalStateException - if the base directory was set incorrectly (i.e. if it doesn't exist or isn't a directory).
      • clearResults

        protected void clearResults()
        Clear the result caches for a scan.
      • slowScan

        protected void slowScan()
        Top level invocation for a slow scan. A slow scan builds up a full list of excluded/included files/directories, whereas a fast scan will only have full results for included files, as it ignores directories which can't possibly hold any included files/directories.

        Returns immediately if a slow scan has already been completed.

      • scandir

        protected void scandir​(java.io.File dir,
                               java.lang.String vpath,
                               boolean fast)
        Scan the given directory for files and directories. Found files and directories are placed in their respective collections, based on the matching of includes, excludes, and the selectors. When a directory is found, it is scanned recursively.
        Parameters:
        dir - The directory to scan. Must not be null.
        vpath - The path relative to the base directory (needed to prevent problems with an absolute path when using dir). Must not be null.
        fast - Whether or not this call is part of a fast scan.
