<PRE>
public void <B>add</B>(<A HREF="../../java/security/Permission.html">Permission</A>&nbsp;permission)</PRE>
<DL>
<DD>Adds a permission object to the PermissionCollection for the class the
 permission belongs to. For example, if <i>permission</i> is a FilePermission,
 it is added to the FilePermissionCollection stored in this
 Permissions object. 
 
 This method creates
 a new PermissionCollection object (and adds the permission to it)
 if an appropriate collection does not yet exist. <p><DD><DL>

implies</H3>
<PRE>
public boolean <B>implies</B>(<A HREF="../../java/security/Permission.html">Permission</A>&nbsp;permission)</PRE>
<DL>
<DD>Checks to see if this object's PermissionCollection for permissions of the
 specified permission's type implies the permissions 
 expressed in the <i>permission</i> object. Returns true if the combination
 of permissions in the appropriate PermissionCollection (e.g., a
 FilePermissionCollection for a FilePermission) together imply the
 specified permission.
 
 <p>For example, suppose there is a FilePermissionCollection in this Permissions
 object, and it contains one FilePermission that specifies "read" access for
 all files in all subdirectories of the "/tmp" directory, and another
 FilePermission that specifies "write" access for all files in the
 "/tmp/scratch/foo" directory. Then if the <code>implies</code> method
 is called with a permission specifying both "read" and "write" access
 to files in the "/tmp/scratch/foo" directory, <code>true</code> is returned.
 <p>Additionally, if this PermissionCollection contains the
 AllPermission, this method will always return true.
