Public class XPRSnamelist Obsolete
Public class XPRSobject  
Public class XPRSprob  
Public class XPRSprobAbstractUserFunction Base class for user functions. You will usually not have to create an instance of this class or its subclasses yourself. Instead the way to create an instance is to use an XPRSprob instance as factory:
C# 
MapFunction f = prob.NlpAddUserFunction("myf", 0, d -> 2 * d);
That is, you create an instance of XPRSprobMapFunctor, XPRSprobVecMapFunctor, XPRSprobMultiMapFunctor, XPRSprobMapDeltaFunctor, XPRSprobVecMapDeltaFunctor, or XPRSprobMultiMapDeltaFunctor and then pass that to the appropriate overload of nlpAddUserFunction. This will register the function with the Xpress problem object and return a user function instance that can then be used in the code to build formulas.
Public class XPRSprobCannotPerformOperationException Exception raised when an operation is attempted for which the model cannot be in a presolved state or in a callback.
Public class XPRSprobCannotReferenceVariablesException Exception raised when a constraint references Variable instances while it should only reference indices.
Protected class XPRSprobColumnCreator Create columns in chunks. Collects column data internally and commits data from time to time. Assumes that columns are not created in other ways while this instance is active.
Public class XPRSprobConstraintCreator Class to buffer constraints and create them in chunks.
Public class XPRSprobGeneralConstraintInfo Return value for [!:.GetGenCons(int, int)].
Public class XPRSprobIISData Return value for [!:.GetIISData(int)];
Public class XPRSprobIISStatusInfo Return value for [!:.IISStatus()].
Public class XPRSprobInvalidStateException Exception that is raised if the problem is not in the correct state. A number of operations cannot be performed using Variable, Inequality etc. instances if the problem is in a presolved state or if they are invoked from a callback. This Exception (or a subclass of it) is used to signal this kind of error.
Public class XPRSprobMapDeltaFunction An R -> R function that also provides the derivative.
Public class XPRSprobMapFunction An R -> R function.
Public class XPRSprobMatrixInfo Return value for [!:.GetCols(int, int)], [!:.GetRows(int, int)], [!:.GetMQObj(int, int)]. Instances of this class can represent row-wise or column-wise representations of a matrix. The type of representation is specified by the function that returned the instance.
Public class XPRSprobMIPEntityInfo Return value for [!:.GetMIPEntities()], [!:.GetDiscreteCols()], [!:.GetSetDefinitions()].
Public class XPRSprobMultiMapDeltaFunction An R^n -> R^m function that also provides partial derivatives.
Public class XPRSprobMultiMapFunction An R^n -> R^m function.
Public class XPRSprobRowCreator Create rows in chunks. Collects row data internally and commits data from time to time. Assumes that rows are not created in other ways while this instance is active.
Public class XPRSprobRowInfo Sparse row information. The non-zero indices of variables in the row are given by the two arrays ind and val. The coefficient for variable ind[k] is val[k].
Public class XPRSprobSolution Solution data.
Public class XPRSprobStatusSolution Solution information that also contains a status value.
Public class XPRSprobVecMapDeltaFunction An R^n -> R function that also provides partial derivatives.
Public class XPRSprobVecMapFunction An R^n -> R function.
