toString</H3>
<PRE>
public <A HREF="../../java/lang/String.html">String</A> <B>toString</B>()</PRE>
<DL>
<DD>Returns a string describing this PermissionCollection object,
 providing information about all the permissions it contains.
 The format is:
 <pre>
 super.toString() (
   // enumerate all the Permission
   // objects and call toString() on them,
   // one per line..
 )</pre>

 <code>super.toString</code> is a call to the <code>toString</code>
 method of this
 object's superclass, which is Object. The result is
 this PermissionCollection's type name followed by this object's
 hashcode, thus enabling clients to differentiate different
 PermissionCollections object, even if they contain the same permissions.<DD><DL>
