Usage

From source file:com.quartercode.jtimber.rh.agent.util.ResourceLister.java

/**
 * Creates a new resource lister that lists all occurrences of the given classpath resource on the classpath as {@link Path}s.
 * It is possible that multiple paths are listed if multiple classpath entries (e.g. jars) contain the resource.
 * For example, if two jars contain the directory {@code /test1/test2}, this class lists both both.<br>
 * <br>//from  w ww  . j a v a2s  .  c  o  m
 * Note that this class uses a workaround to create path objects for files which are located inside a jar.
 * Because of that, each instance of this class should be closed after the paths have been used.
 * However, the paths might no longer be accessible after the lister has been closed.
 * 
 * @param resourcePath The path that defines the classpath resource whose occurrences should be listed.
 * @param throwAll Whether {@link IOException}s, which are thrown during the retrieval of one specific resource and would therefore also interrupt
 *        the retrieval of other resources, should be thrown.
 *        If this is {@code false}, the regarding exceptions are logged as errors.
 * @throws IOException Something goes wrong while retrieving the resource occurrences.
 *         If {@code throwAll} is {@code true} and an occurrence is located inside a jar, a jar reading exception is also possible.
 * @throws IllegalArgumentException The resource path doesn't start with "/" (this method cannot list relative resources).
 * @see #getResourcePaths()
