Constructor Detail

QEdge

public QEdge(org.plasma.query.dsl.PathNode source,
             String sourceProperty)

Constructor which instantiates a domain query path node. A path may span multiple namespaces and therefore Java inplementation packages based on the Condiguration. Note: while this constructor is public, it is not for application use!

Parameters:

source - the source path node

sourceProperty - the source property logical name
