Detailed Description

template<typename DOM_NODE_TYPE>
struct ddl::dd::DDFromXMLFactory< DOM_NODE_TYPE >

Factory to create a DataDefinition out of a XML based description.

This factory uses a template type DOM_NODE_TYPE which is design to follow the a concept class type definition of the a_util::DOMElement.

Template Parameters

DOM_NODE_TYPE

a DOMElement class must implement following funtions:

string getAttribute(const std::string& name) const;
string getData() const;
bool findNode(const std::string& node_name, DOM_NODE_TYPE& result_node) const;
bool findNodes(const std::string& node_names, std::list<DOM_NODE_TYPE>& result_nodes) const;
