TESERIALIZATIONEXPORT te::se::ParameterValue * ReadParameterValue(te::xml::Reader &reader)
Utility methods for Symbology serialization.
They are used to define a graph of points.
This class models a XML reader object.

virtual bool next()=0
It gets the next event to be read.
virtual double getElementValueAsDouble() const
It returns the element data value in the case of VALUE node.

They are used to define a graph of points.
ParameterValue * getValue() const
virtual NodeType getNodeType() const =0
It return the type of node read.
virtual std::string getElementLocalName() const =0
It returns the local part of the element name in the case of an element node.
