</PRE>
<P>
Controls access to management objects in the Device Management Tree (DMT). It
is intended to control local access to the DMT. DmtPermission target string
identifies the management object URI and the action field lists the OMA DM
commands that are permitted on the management object. Example:
<pre>
DmtPermission("./OSGi/bundles", "Add,Replace,Get");
</pre>
This means that owner of this permission can execute Add, Replace and Get
commands on the ./OSGi/bundles management object. It is possible to use
wildcards in both the target and the actions field. Wildcard in the target
field means that the owner of the permission can access children nodes of the
target node. Example:
<pre>
DmtPermission("./OSGi/bundles/*", "Get");
</pre>
This means that owner of this permission has Get access on every child node
of ./OSGi/bundles. The asterix does not necessarily have to follow a '/'
character. For example the <code>&quot;./OSGi/a*&quot;</code> target matches
the <code>./OSGi/applications</code> subtree.
<p>
If wildcard is present in the actions field, all legal OMA DM commands are
allowed on the designated nodes(s) by the owner of the permission. Action
names are interpreted case-insensitively, but the canonical action string
returned by <A HREF="../../../info/dmtree/security/DmtPermission.html#getActions()"><CODE>getActions()</CODE></A> uses the forms defined by the action
constants.

public <B>DmtPermission</B>(java.lang.String dmtUri,

<DL>
<DD>Creates a new DmtPermission object for the specified DMT URI with the
specified actions. The given URI can be:
<ul>
<li> <code>"*"</code>, which matches all valid
(see <A HREF="../../../info/dmtree/Uri.html#isValidUri(java.lang.String)"><CODE>Uri.isValidUri(java.lang.String)</CODE></A>) absolute URIs;
<li> the prefix of an absolute URI followed by the <code>*</code>
character (for example <code>"./OSGi/L*"</code>), which matches all valid
absolute URIs beginning with the given prefix;
<li> a valid absolute URI, which matches itself.
</ul>
<p>
Since the <code>*</code> character is itself a valid URI character, it
can appear as the last character of a valid absolute URI. To distinguish
this case from using <code>*</code> as a wildcard, the <code>*</code>
character at the end of the URI must be escaped with the <code>\</code>
charater. For example the URI <code>"./a*"</code> matches
<code>"./a"</code>, <code>"./aa"</code>, <code>"./a/b"</code> etc. while
<code>"./a\*"</code> matches <code>"./a*"</code> only.
<p>
The actions string must either be "*" to allow all actions, or it must
contain a non-empty subset of the valid actions, defined as constants in
this class.

<A NAME="equals(java.lang.Object)"><!-- --></A><H3>
equals</H3>
<PRE>
public boolean <B>equals</B>(java.lang.Object obj)</PRE>
<DL>
<DD>Checks whether the given object is equal to this DmtPermission instance.
Two DmtPermission instances are equal if they have the same target string
and the same action mask. The "*" action mask is considered equal to a
mask containing all actions.

<DD><DL>
<DT><B>Parameters:</B><DD><CODE>obj</CODE> - the object to compare to this DmtPermission instance
<DT><B>Returns:</B><DD><code>true</code> if the parameter represents the same
permissions as this instance</DL>

<A NAME="getActions()"><!-- --></A><H3>
getActions</H3>
<PRE>
public java.lang.String <B>getActions</B>()</PRE>
<DL>
<DD>Returns the String representation of the action list. The allowed actions
are listed in the following order: Add, Delete, Exec, Get, Replace. The
wildcard character is not used in the returned string, even if the class
was created using the "*" wildcard.

<A NAME="hashCode()"><!-- --></A><H3>
hashCode</H3>
<PRE>
public int <B>hashCode</B>()</PRE>
<DL>
<DD>Returns the hash code for this permission object. If two DmtPermission
objects are equal according to the <A HREF="../../../info/dmtree/security/DmtPermission.html#equals(java.lang.Object)"><CODE>equals(java.lang.Object)</CODE></A> method, then calling
this method on each of the two DmtPermission objects must produce the

<A NAME="implies(java.security.Permission)"><!-- --></A><H3>
implies</H3>
<PRE>
public boolean <B>implies</B>(java.security.Permission p)</PRE>
<DL>
<DD>Checks if this DmtPermission object "implies" the specified
permission. This method returns <code>false</code> if and only if at
least one of the following conditions are fulfilled for the specified
permission:
<ul>
<li>it is not a DmtPermission
<li>its set of actions contains an action not allowed by this permission
