BasicPermission</H3>
<PRE>
public <B>BasicPermission</B>(<A HREF="../../java/lang/String.html">String</A>&nbsp;name)</PRE>
<DL>
<DD>Creates a new BasicPermission with the specified name.
 Name is the symbolic name of the permission, such as
 "setFactory",
 "print.queueJob", or "topLevelWindow", etc. An asterisk
 may appear at the end of the name, following a ".", or by itself, to
 signify a wildcard match.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>name</CODE> - the name of the BasicPermission.<DT><B>Throws:</B><DD><CODE><A HREF="../../java/lang/NullPointerException.html">NullPointerException</A></CODE> - if <code>name</code> is <code>null</code>.<DD><CODE><A HREF="../../java/lang/IllegalArgumentException.html">IllegalArgumentException</A></CODE> - if <code>name</code> is empty.</DL>

<DL>
<DD>Creates a new BasicPermission object with the specified name.
 The name is the symbolic name of the BasicPermission, and the
 actions String is currently unused. This
 constructor exists for use by the <code>Policy</code> object
 to instantiate new Permission objects.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>name</CODE> - the name of the BasicPermission.<DD><CODE>actions</CODE> - ignored.<DT><B>Throws:</B><DD><CODE><A HREF="../../java/lang/NullPointerException.html">NullPointerException</A></CODE> - if <code>name</code> is <code>null</code>.<DD><CODE><A HREF="../../java/lang/IllegalArgumentException.html">IllegalArgumentException</A></CODE> - if <code>name</code> is empty.</DL>

implies</H3>
<PRE>
public boolean <B>implies</B>(<A HREF="../../java/security/Permission.html">Permission</A>&nbsp;p)</PRE>
<DL>
<DD>Checks if the specified permission is "implied" by
 this object.
 <P>
 More specifically, this method returns true if:<p>
 <ul>
 <li> <i>p</i>'s class is the same as this object's class, and<p>
 <li> <i>p</i>'s name equals or (in the case of wildcards)
      is implied by this object's
      name. For example, "a.b.*" implies "a.b.c".

<DT><B>Parameters:</B><DD><CODE>p</CODE> - the permission to check against.<DT><B>Returns:</B><DD>true if the passed permission is equal to or

 and has the same name as this object.

<DT><B>Parameters:</B><DD><CODE>obj</CODE> - the object we are testing for equality with this object.<DT><B>Returns:</B><DD>true if <i>obj</i> is a BasicPermission, and has the same name

<A NAME="hashCode()"><!-- --></A><H3>
hashCode</H3>
<PRE>
public int <B>hashCode</B>()</PRE>
<DL>
<DD>Returns the hash code value for this object.
 The hash code used is the hash code of the name, that is,
 <code>getName().hashCode()</code>, where <code>getName</code> is
 from the Permission superclass.<DD><DL>
<DT><B>Overrides:</B><DD><CODE><A HREF="../../java/security/Permission.html#hashCode()">hashCode</A></CODE> in class <CODE><A HREF="../../java/security/Permission.html">Permission</A></CODE></DL>

<PRE>
public <A HREF="../../java/lang/String.html">String</A> <B>getActions</B>()</PRE>
<DL>
<DD>Returns the canonical string representation of the actions,

newPermissionCollection</H3>
<PRE>
public <A HREF="../../java/security/PermissionCollection.html">PermissionCollection</A> <B>newPermissionCollection</B>()</PRE>
<DL>
<DD>Returns a new PermissionCollection object for storing BasicPermission
 objects.
 <p>
 A BasicPermissionCollection stores a collection of
 BasicPermission permissions.

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