Method Detail

• implies

  public boolean implies(Permission p)

  Checks if the specified permission is "implied" by this object.

  More specifically, this method returns true if:

  • p's class is the same as this object's class, and

  • p's name equals or (in the case of wildcards) is implied by this object's name. For example, "a.b.*" implies "a.b.c".

  Specified by:

  implies in class Permission

  Parameters:

  p - the permission to check against.

  Returns:

  true if the passed permission is equal to or implied by this permission, false otherwise.

• equals

  public boolean equals(Object obj)

  Checks two BasicPermission objects for equality. Checks that obj's class is the same as this object's class and has the same name as this object.

  Specified by:

  equals in class Permission

  Parameters:

  obj - the object we are testing for equality with this object.

  Returns:

  true if obj's class is the same as this object's class and has the same name as this BasicPermission object, false otherwise.

  Object.hashCode(), HashMap

• hashCode

  public int hashCode()

  Returns the hash code value for this object. The hash code used is the hash code of the name, that is, getName().hashCode(), where getName is from the Permission superclass.

  Specified by:

  hashCode in class Permission

  Returns:

  a hash code value for this object.

  See Also:

  Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

• getActions

  public String getActions()

  Returns the canonical string representation of the actions, which currently is the empty string "", since there are no actions for a BasicPermission.

  Specified by:

  getActions in class Permission

  Returns:

  the empty string "".

• newPermissionCollection

  public PermissionCollection newPermissionCollection()

  Returns a new PermissionCollection object for storing BasicPermission objects.

  BasicPermission objects must be stored in a manner that allows them to be inserted in any order, but that also enables the PermissionCollection implies method to be implemented in an efficient (and consistent) manner.

  Overrides:

  newPermissionCollection in class Permission

  Returns:

  a new PermissionCollection object suitable for storing BasicPermissions.
