Class IloXmlContext

An instance of IloXmlContext allows you to serialize an IloModel or an IloSolution in XML.

You can write an IloModel using IloXmlContext::writeModel, write an IloSolution using IloXmlContext::writeSolution, or write both using IloXmlContext::writeModelAndSolution.

You can read an IloModel in XML using IloXmlContext::readModel, read an IloSolution in XML using IloXmlContext::readSolution, or read both using IloXmlContext::readModelAndSolution.

Other products should add their own serialization class and add them to the plug-in using the member functions IloXmlContext::registerXML and IloXmlContext::registerXMLArray.

For example, you can write:

  IloModel model(env);
	IloSolution solution(env);
   ...;
  IloXmlContext context(env);
  context.writeModel(model, "model.xml");
  context.writeSolution(solution, "solution.xml");
 

or you can write

  IloModel model(env);
	IloSolution solution(env);
	IloXmlContext context(env);
	context.readModel(model, "model.xml");
	context.readSolution(solution, "solution.xml");
 

This constructor creates an XML context and makes it part of the environment env.

This constructor creates a XML context from its implementation object.

This member function deletes the invoking XML context.

This member function returns the XML ID of the child unparsed XML element in cases where a problem occurs when reading an IloModel.

This member function returns the XML tag of the child unparsed XML element in cases where a problem occurs when reading an IloModel

This member function returns the XML ID list of the unparsed XML elements in cases where a problem occurs when reading an IloModel. The list is composed of the tags from the parent to the child elements.

This member function returns the IloXmlContextI implementation.

This member function returns the XML ID of the parent unparsed XML element in cases where a problem occurs when reading an IloModel.

This member function returns the XML tag of the parent unparsed XML element in cases where a problem occurs when reading an IloModel.

This member function returns the XML tag list of the unparsed XML elements in cases where a problem occurs when reading an IloModel. The list is composed of the tags from the parent to the child elements.

This member function returns the name of the extractable called in cases where a problem occurs when reading an IloModel.

This member function returns the write precision for floats

This member function reads model from an XML stream.

This member function reads model from the XML file fileName.

This member function reads model and solution from their respective XML files, modelFileName and solutionFileName.

This member function tries to read all extractables from the XML element.

This member function reads solution from an XML stream.

This member function reads solution from the XML file fileName.

This member function reads an IloSolution object from an XML element.

This member function registers the serialization class of an extractable with a linked ID, usually its RTTI index. In write mode, the RTTI index is used to catch the correct serialization class.

In read mode, IloXmlInfo::getTagName is used to link the correct serialization class to the correct tag.

   IlpXmlContext context(env);
	  context.registerXML(IloAllDiffI::GetTypeIndex(), new (env) IloXmlInfo_AllDiff(context));
 

This member function registers the serialization class of an array of extractables with a linked ID.

   context.registerXMLArray(new (env) IloXmlInfo_SOS2Array(context));
 

This member function sets the write mode. The write mode can be set to NoUnknown or EvenUnknown. NoUnknown throws an exception if an attempt is made to serialize an unknown extractable. EvenUnknown writes a Unknown tag with the name of the extractable in a type attribute.

This member function sets the write precision for floats. By default, there is no rounding mode on an IloNum or an IloNumArray. You can also choose the no rounding mode with the IloNoRoundingMode constant.

This member function writes model to the file fileNamein XML format.

This member function writes model to the file modelFileName and solution to the file solutionFileName in XML format.

This member function writes a specified extractable. It is used from the serialization class of an extractable to write a embedded extractable.

The IloOr object calls this method on its constrained vars.

This member function writes solution to the file fileName in XML format.

This member function writes a specified extractable of a solution in XML. It is used from the serialization class of an extractable to write an embedded extractable.
