<div class="block">DmtSession provides concurrent access to the DMT. All DMT manipulation
commands for management applications are available on the <code>DmtSession</code>
interface. The session is associated with a root node which limits the
subtree in which the operations can be executed within this session.
<p>
Most of the operations take a node URI as parameter, which can be either an
absolute URI (starting with "./") or a URI relative to the root
node of the session. The empty string as relative URI means the root URI the
session was opened with. All segments of a URI must be within the segment
length limit of the implementation, and the special characters '/' and '\'
must be escaped (preceded by a '\').
<p>
See the <a href="../../../../org/osgi/service/dmt/Uri.html#encode-java.lang.String-"><code>Uri.encode(String)</code></a> method for support on escaping invalid
characters in a URI.
<p>
If the URI specified does not correspond to a legitimate node in the tree an
exception is thrown. The only exception is the <a href="../../../../org/osgi/service/dmt/DmtSession.html#isNodeUri-java.lang.String-"><code>isNodeUri(String)</code></a>
method which returns <code>false</code> in case of an invalid URI.
<p>
Each method of <code>DmtSession</code> that accesses the tree in any way can throw
<code>DmtIllegalStateException</code> if the session has been closed or
invalidated (due to timeout, fatal exceptions, or unexpectedly unregistered
plugins).</div>

<p>
This method can fail even if all operations were successful. This can
happen due to some multi-node semantic constraints defined by a specific
implementation. For example, node A can be required to always have
children A/B, A/C and A/D. If this condition is broken when
<code>commit()</code> is executed, the method will fail, and throw a
<code>METADATA_MISMATCH</code> exception.
<p>
An error situation can arise due to the lack of a two phase commit
mechanism in the underlying plugins. As an example, if plugin A has
committed successfully but plugin B failed, the whole session must fail,
but there is no way to undo the commit performed by A. To provide
predictable behaviour, the commit operation should continue with the
remaining plugins even after detecting a failure. All exceptions received
from failed commits are aggregated into one <code>TRANSACTION_ERROR</code>
exception thrown by this method.
<p>
In many cases the tree is not the only way to manage a given part of the
system. It may happen that while modifying some nodes in an atomic
session, the underlying settings are modified in parallel outside the
scope of the DMT. If this is detected during commit, an exception with
the code <code>CONCURRENT_ACCESS</code> is thrown.</div>

The copy method is essentially a convenience method that could be
substituted with a sequence of retrieval and update operations. This
determines the permissions required for copying. However, some
optimization can be possible if the source and target nodes are all
handled by DmtAdmin or by the same plugin. In this case, the handler
might be able to perform the underlying management operation more
efficiently: for example, a configuration table can be copied at once
instead of reading each node for each entry and creating it in the new
tree.

document.
<p>
For interior nodes, a <code>null</code> type string means that there is no DDF
document overriding the tree structure defined by the ancestors. For leaf
nodes, it requests that the default MIME type is used for the given node.
If the node does not have a default MIME type this method will throw a
<code>DmtException</code> with error code <code>METADATA_MISMATCH</code>. Note that
a node might have a default MIME type even if there is no meta-data for
the node or its meta-data does not specify the default.
<p>
MIME types must conform to the definition in RFC 2045. Interior node type
identifiers must follow the format defined in section 7.7.7.2 of the OMA
Device Management Tree and Description document. Checking the validity of
the type string does not have to be done by the DmtAdmin, this can be
left to the plugin handling the node (if any), to avoid unnecessary
double-checks.</div>
