Examples of java.io.FilePermission.implies()

java.io.FilePermission.implies()
Checks if this FilePermission object "implies" the specified permission.
More specifically, this method returns true if:
- p is an instanceof FilePermission,
- p's actions are a proper subset of this object's actions, and
- p's pathname is implied by this object's pathname. For example, "/tmp/*" implies "/tmp/foo", since "/tmp/*" encompasses all files in the "/tmp" directory, including the one named "foo".
@param p the permission to check against. @return true if the specified permission is notnull and is implied by this object, false otherwise.

    p.add(new FilePermission("/tmp/p", "read"));
    p.add(new FilePermission("/tmp/p", "read"));


    // Classpath didn't handle dirs without a file separator correctly
    FilePermission fp1 = new FilePermission("/tmp", "read");
    harness.check(fp1.implies(fp1));


    // Test the constructor's checking of its arguments.
    harness.checkPoint("constructor file arg checking");
    try {
      harness.check(new FilePermission(null, "read") == null);
