ConstraintCreator Methods

The XPRSprobConstraintCreator type exposes the following members.

Methods
  Name Description
Public method AddGeneralConstraint Add a general constraint in a single shot.
Public method AddNonzero(Int32, Double) Add a single non-zero to the current row.
(Inherited from XPRSprobRowCreator)
Public method AddNonzero(Int32, Int32, Double) Add a single quadratic non-zero to the current row. Note: The information is passed to the low-level API as is! Check the C reference documentation for how constraints are represented there. In particular, check whether off-diagonal elements may have to be doubled or halved.
(Inherited from XPRSprobRowCreator)
Public method AddNonzeros Add coefficients to the current row.
(Inherited from XPRSprobRowCreator)
Public method AddPWL Add a piecewise linear constraint.
Public method AddRhs Add a value to the right-hand side of the current row.
(Inherited from XPRSprobRowCreator)
Public method AddRow Add a row in a single shot.
(Inherited from XPRSprobRowCreator)
Public method AddSet Add a new SOS constraint.
Public method AddToken Append a token to this extractor.
(Inherited from XPRSprobRowCreator)
Public method ApplyRange Apply a range constraint to the row that is currently built. The function assumes that the right-hand side has already been setup. It is an error to modify type or right-hand side of the current row after calling this function.
(Inherited from XPRSprobRowCreator)
Public method CheckForVariables Check whether referencing Variable instances should raise an exception. If it should, then raise the required exception.
(Inherited from XPRSprobRowCreator)
Public method Commit Flush all buffers.
(Overrides XPRSprobRowCreatorCommit)
Public method ConditionalCommit Check whether buffers are very big and need committing. If the buffer sizes exceed the thresholds then call commit.
(Overrides XPRSprobRowCreatorConditionalCommit)
Public method DereferenceVariable Derefence a value. Converts a variable object into a variable index. This is different from x.GetIndex() as it also checks whether the problem for which we are extracting the current formula is currently in a state in which variables can be Dereferenced (i.e. not in a callback and not in a presolved state). If it is not then an exception is raised.
(Inherited from XPRSprobRowCreator)
Public method EndExpression Signal that a (sub)expression has been extracted.
(Inherited from XPRSprobRowCreator)
Public method Equals Determines whether the specified object is equal to the current object.
(Inherited from Object)
Public method FinishRow Tell this instance that all data for the current rows has been added. This calls ConditionalCommit().
(Inherited from XPRSprobRowCreator)
Public method GetHashCode Serves as the default hash function.
(Inherited from Object)
Public method GetPostfixExtractor Get a IPostfixExtractor that can extract formulas into this RowCreator.
(Inherited from XPRSprobRowCreator)
Public method GetRowCount Get the current row count, including buffered rows that are not yet committed.
(Inherited from XPRSprobRowCreator)
Public method GetType Gets the Type of the current instance.
(Inherited from Object)
Public method NormalizeCurrentRow Sort and merge duplicates in the current row. Must be called before FinishRow() is called.
(Inherited from XPRSprobRowCreator)
Public method SetName Set the name of the current row.
(Inherited from XPRSprobRowCreator)
Public method SetType Set the type of the current row.
(Inherited from XPRSprobRowCreator)
Public method StartExpression
(Inherited from XPRSprobRowCreator)
Public method ToString Returns a string that represents the current object.
(Inherited from Object)
Public method Undo Undo all changes ever done by this instance. The creator should not be used after calling this function.
(Overrides XPRSprobRowCreatorUndo)
