XmlQueryContext::getVariableValue

APIRef

#include <DbXml.hpp>

XmlValue XmlQueryContext::getVariableValue(const std::string &name);

Description

The XmlQueryContext::getVariableValue method returns the value bound to the variable name.

If there is no value, the XmlQueryContext::getVariableValue method will return DB_NOTFOUND. Otherwise, the XmlQueryContext::getVariableValue method throws an exception that encapsulates a non-zero error value on failure.

Errors

The XmlQueryContext::getVariableValue method may fail and throw an exception encapsulating a non-zero error for the following conditions:

EINVAL
An invalid flag value or parameter was specified.

The XmlQueryContext::getVariableValue method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the XmlQueryContext::getVariableValue method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
