#include <DbXml.hpp>
void XmlContainer::updateDocument(
DbTxn *txn, XmlDocument &document, XmlUpdateContext *context= 0);
Description: XmlContainer::updateDocument
The XmlContainer::updateDocument method updates a XmlDocument in
the container. The document must have been retrieved from the container
using the XmlContainer::getDocument or XmlContainer::queryWithXPath
methods, and must still exist within the container. The document content
is indexed according to the container indexing specification, with index
keys being removed for the previous document content, and added for the
updated document content.
Parameters
- txn
-
If the operation is to be transaction-protected, the
txn parameter is a transaction handle returned from
DbEnv::txn_begin, otherwise, NULL.
- document
-
The XmlDocument to be inserted into the
XmlContainer.
- context
-
The optional XmlUpdateContext object provides
a performance improvement by caching internal objects over multiple
calls to the container update methods.
Errors
The XmlContainer::updateDocument method
may fail and throw
XmlException,
encapsulating one of the following non-zero errors:
- CONTAINER_CLOSED
- The container is closed.
- DATABASE_ERROR
- An error occurred in an underlying Berkeley DB database. The
XmlException::getDbError method will return the error code for the
error.
- DOCUMENT_NOT_FOUND
- The specified document is not in the XmlContainer.
- INDEXER_PARSER_ERROR
- The XML Indexer could not parse the document.
