<P>
An implementation of this interface takes the responsibility of handling node
execute requests requests in a subtree of the DMT.
<p>
In an OSGi environment such implementations should be registered at the OSGi
service registry specifying the list of root node URIs in a
<code>String</code> array in the <code>execRootURIs</code> registration
parameter.

<DL>
<DD>Execute the given node with the given data. This operation corresponds to
the EXEC command in OMA DM.
<p>
The semantics of an execute operation and the data parameter it takes
depends on the definition of the managed object on which the command is
issued. Session information is given as it is needed for sending alerts
back from the plugin. If a correlation ID is specified, it should be used
as the <code>correlator</code> parameter for alerts sent in response to
this execute operation.
<p>
The <code>nodePath</code> parameter contains an array of path segments
identifying the node to be executed in the subtree of this plugin. This
is an absolute path, so the first segment is always ".".
Special characters appear escaped in the segments.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>session</CODE> - a reference to the session in which the operation was
issued, must not be <code>null</code><DD><CODE>nodePath</CODE> - the absolute path of the node to be executed, must not be
<code>null</code><DD><CODE>correlator</CODE> - an identifier to associate this operation with any
alerts sent in response to it, can be <code>null</code><DD><CODE>data</CODE> - the parameter of the execute operation, can be
<code>null</code>
<DT><B>Throws:</B>
<DD><CODE><A HREF="../../../info/dmtree/DmtException.html" title="class in info.dmtree">DmtException</A></CODE> - with the following possible error codes:
<ul>
<li><code>NODE_NOT_FOUND</code> if the node does not exist and
the plugin does not allow executing unexisting nodes
<li><code>METADATA_MISMATCH</code> if the command failed
because of meta-data restrictions
<li><code>DATA_STORE_FAILURE</code> if an error occurred while
accessing the data store
<li><code>COMMAND_FAILED</code> if some unspecified error is
encountered while attempting to complete the command
