Example 27 with PathMatcher

use of java.nio.file.PathMatcher in project jetty.project by eclipse.

the class BaseHome method getPaths.

/**
     * Get a List of {@link Path}s from a provided pattern.
     * <p>
     * Resolution Steps:
     * <ol>
     * <li>If the pattern starts with "regex:" or "glob:" then a standard {@link PathMatcher} is built using
     * {@link java.nio.file.FileSystem#getPathMatcher(String)} as a file search.</li>
     * <li>If pattern starts with a known filesystem root (using information from {@link java.nio.file.FileSystem#getRootDirectories()}) then this is assumed to
     * be a absolute file system pattern.</li>
     * <li>All other patterns are treated as relative to BaseHome information:
     * <ol>
     * <li>Search ${jetty.home} first</li>
     * <li>Search ${jetty.base} for overrides</li>
     * </ol>
     * </li>
     * </ol>
     * <p>
     * Pattern examples:
     * <dl>
     * <dt><code>lib/logging/*.jar</code></dt>
     * <dd>Relative pattern, not recursive, search <code>${jetty.home}</code> then <code>${jetty.base}</code> for lib/logging/*.jar content</dd>
     * 
     * <dt><code>lib/**&#47;*-dev.jar</code></dt>
     * <dd>Relative pattern, recursive search <code>${jetty.home}</code> then <code>${jetty.base}</code> for files under <code>lib</code> ending in
     * <code>-dev.jar</code></dd>
     * 
     * <dt><code>etc/jetty.xml</code></dt>
     * <dd>Relative pattern, no glob, search for <code>${jetty.home}/etc/jetty.xml</code> then <code>${jetty.base}/etc/jetty.xml</code></dd>
     * 
     * <dt><code>glob:/opt/app/common/*-corp.jar</code></dt>
     * <dd>PathMapper pattern, glob, search <code>/opt/app/common/</code> for <code>*-corp.jar</code></dd>
     * 
     * </dl>
     * 
     * <p>
     * Notes:
     * <ul>
     * <li>FileSystem case sensitivity is implementation specific (eg: linux is case-sensitive, windows is case-insensitive).<br>
     * See {@link java.nio.file.FileSystem#getPathMatcher(String)} for more details</li>
     * <li>Pattern slashes are implementation neutral (use '/' always and you'll be fine)</li>
     * <li>Recursive searching is limited to 30 levels deep (not configurable)</li>
     * <li>File System loops are detected and skipped</li>
     * </ul>
     * 
     * @param pattern
     *            the pattern to search.
     * @return the collection of paths found
     * @throws IOException
     *             if error during search operation
