◆ getNodeValue() [2/2]

std::string clang::diff::SyntaxTree::getNodeValue ( NodeId Id) const

Serialize the node attributes to a string representation.

This should uniquely distinguish nodes of the same kind. Note that this function just returns a representation of the node value, not considering descendants.
