40 | /**
|
---|
41 | * Class for scanning a directory for files/directories which match certain
|
---|
42 | * criteria.
|
---|
43 | * <p>
|
---|
44 | * These criteria consist of selectors and patterns which have been specified.
|
---|
45 | * With the selectors you can select which files you want to have included.
|
---|
46 | * Files which are not selected are excluded. With patterns you can include
|
---|
47 | * or exclude files based on their filename.
|
---|
48 | * <p>
|
---|
49 | * The idea is simple. A given directory is recursively scanned for all files
|
---|
50 | * and directories. Each file/directory is matched against a set of selectors,
|
---|
51 | * including special support for matching against filenames with include and
|
---|
52 | * and exclude patterns. Only files/directories which match at least one
|
---|
53 | * pattern of the include pattern list or other file selector, and don't match
|
---|
54 | * any pattern of the exclude pattern list or fail to match against a required
|
---|
55 | * selector will be placed in the list of files/directories found.
|
---|
56 | * <p>
|
---|
57 | * When no list of include patterns is supplied, "**" will be used, which
|
---|
58 | * means that everything will be matched. When no list of exclude patterns is
|
---|
59 | * supplied, an empty list is used, such that nothing will be excluded. When
|
---|
60 | * no selectors are supplied, none are applied.
|
---|
61 | * <p>
|
---|
62 | * The filename pattern matching is done as follows:
|
---|
63 | * The name to be matched is split up in path segments. A path segment is the
|
---|
64 | * name of a directory or file, which is bounded by
|
---|
65 | * <code>File.separator</code> ('/' under UNIX, '\' under Windows).
|
---|
66 | * For example, "abc/def/ghi/xyz.java" is split up in the segments "abc",
|
---|
67 | * "def","ghi" and "xyz.java".
|
---|
68 | * The same is done for the pattern against which should be matched.
|
---|
69 | * <p>
|
---|
70 | * The segments of the name and the pattern are then matched against each
|
---|
71 | * other. When '**' is used for a path segment in the pattern, it matches
|
---|
72 | * zero or more path segments of the name.
|
---|
73 | * <p>
|
---|
74 | * There is a special case regarding the use of <code>File.separator</code>s
|
---|
75 | * at the beginning of the pattern and the string to match:<br>
|
---|
76 | * When a pattern starts with a <code>File.separator</code>, the string
|
---|
77 | * to match must also start with a <code>File.separator</code>.
|
---|
78 | * When a pattern does not start with a <code>File.separator</code>, the
|
---|
79 | * string to match may not start with a <code>File.separator</code>.
|
---|
80 | * When one of these rules is not obeyed, the string will not
|
---|
81 | * match.
|
---|
82 | * <p>
|
---|
83 | * When a name path segment is matched against a pattern path segment, the
|
---|
84 | * following special characters can be used:<br>
|
---|
85 | * '*' matches zero or more characters<br>
|
---|
86 | * '?' matches one character.
|
---|
87 | * <p>
|
---|
88 | * Examples:
|
---|
89 | * <p>
|
---|
90 | * "**\*.class" matches all .class files/dirs in a directory tree.
|
---|
91 | * <p>
|
---|
92 | * "test\a??.java" matches all files/dirs which start with an 'a', then two
|
---|
93 | * more characters and then ".java", in a directory called test.
|
---|
94 | * <p>
|
---|
95 | * "**" matches everything in a directory tree.
|
---|
96 | * <p>
|
---|
97 | * "**\test\**\XYZ*" matches all files/dirs which start with "XYZ" and where
|
---|
98 | * there is a parent directory called test (e.g. "abc\test\def\ghi\XYZ123").
|
---|
99 | * <p>
|
---|
100 | * Case sensitivity may be turned off if necessary. By default, it is
|
---|
101 | * turned on.
|
---|
102 | * <p>
|
---|
103 | * Example of usage:
|
---|
104 | * <pre>
|
---|
105 | * String[] includes = {"**\\*.class"};
|
---|
106 | * String[] excludes = {"modules\\*\\**"};
|
---|
107 | * ds.setIncludes(includes);
|
---|
108 | * ds.setExcludes(excludes);
|
---|
109 | * ds.setBasedir(new File("test"));
|
---|
110 | * ds.setCaseSensitive(true);
|
---|
111 | * ds.scan();
|
---|
112 | *
|
---|
113 | * System.out.println("FILES:");
|
---|
114 | * String[] files = ds.getIncludedFiles();
|
---|
115 | * for (int i = 0; i < files.length; i++) {
|
---|
116 | * System.out.println(files[i]);
|
---|
117 | * }
|
---|
118 | * </pre>
|
---|
119 | * This will scan a directory called test for .class files, but excludes all
|
---|
120 | * files in all proper subdirectories of a directory called "modules"
|
---|
121 | *
