@deftypemethod BasicPermission {public boolean} implies (java.security.Permission@w{ }@var{perm}) 
This method tests to see if the specified permission is implied by 
 this permission.  This will be true if the following conditions are met:
 


 
@itemize @bullet

 
@item
The specified object is an instance of @code{BasicPermission}, 
 or a subclass.
 
@item
The name of the specified permission is identical to this permission's
 name or the name of the specified permission satisfies a wildcard match 
 on this permission.
 
@end itemize

@end deftypemethod
@deftypemethod BasicPermission {public boolean} equals (java.lang.Object@w{ }@var{obj}) 
This method tests to see if this object is equal to the specified
 @code{Object}.  This will be true if and only if the specified
 object meets the following conditions:
 


 
@itemize @bullet

 
@item
It is an instance of @code{BasicPermission}, or a subclass.
 
@item
It has the same name as this permission.
 
@end itemize

@end deftypemethod
@deftypemethod BasicPermission {public int} hashCode () 
This method returns a hash code for this permission object.  The hash
 code returned is the value returned by calling the @code{hashCode}
 method on the @code{String} that is the name of this permission.
@end deftypemethod
@deftypemethod BasicPermission {public String} getActions () 
This method returns a list of the actions associated with this 
 permission.  This method always returns the empty string ("") since
 this class ignores actions.
@end deftypemethod
@deftypemethod BasicPermission {public PermissionCollection} newPermissionCollection () 
This method returns an instance of @code{PermissionCollection}
 suitable for storing @code{BasicPermission} objects.  This returns
 be a sub class of @code{PermissionCollection}
 that allows for an efficient and consistent implementation of
 the @code{implies} method.  The collection doesn't handle subclasses
 of BasicPermission correctly; they must override this method.

the underlying output stream.
@end deftypemethod
@deftypemethod DigestOutputStream {public void} write (byte[]@w{ }@var{b}, int@w{ }@var{off}, int@w{ }@var{len}) @*throws IOException
Updates the hash if the on flag is true and then writes the bytes
to the underlying output stream.
@end deftypemethod
@deftypemethod DigestOutputStream {public void} on (boolean@w{ }@var{on}) 
Sets the flag specifying if this DigestOutputStream updates the
digest in the write() methods. The default is on;
@end deftypemethod
@deftypemethod DigestOutputStream {public String} toString () 
Converts the output stream and underlying message digest to a string.
@end deftypemethod
@deftypemethod Guard {public void} checkGuard (java.lang.Object@w{ }@var{obj}) @*throws SecurityException
This method tests whether or not access is allowed to the specified
 guarded object.  Access is allowed if this method returns silently.  If
 access is denied, an exception is generated.
