ConstraintCreator Methods
The XPRSprob.ConstraintCreator type exposes the following members.
| Name | Description | |
|---|---|---|
 |
AddGeneralConstraint |
Add a general constraint in a single shot.
|
|
AddNonzero(Int32, Double) |
Add a single non-zero to the current row.
(Inherited from XPRSprob.RowCreator.) |
|
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 XPRSprob.RowCreator.) |
|
AddNonzeros |
Add coefficients to the current row.
(Inherited from XPRSprob.RowCreator.) |
|
AddPWL |
Add a piecewise linear constraint.
|
|
AddRhs |
Add a value to the right-hand side of the current row.
(Inherited from XPRSprob.RowCreator.) |
|
AddRow |
Add a row in a single shot.
(Inherited from XPRSprob.RowCreator.) |
|
AddSet |
Add a new SOS constraint.
|
|
AddToken |
Append a token to this extractor.
(Inherited from XPRSprob.RowCreator.) |
|
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 XPRSprob.RowCreator.) |
|
CheckForVariables |
Check whether referencing
Variable instances should raise an exception. If it should, then raise the required exception. The text in this exception is the
errorIfVariables field that was passed to the constructor.
(Inherited from XPRSprob.RowCreator.) |
|
Commit |
Flush all buffers.
(Overrides XPRSprob.RowCreator.Commit().) |
|
ConditionalCommit |
Check whether buffers are very big and need committing. If the buffer sizes exceed the thresholds then call
commit.
(Overrides XPRSprob.RowCreator.ConditionalCommit().) |
|
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 XPRSprob.RowCreator.) |
|
EndExpression |
Signal that a (sub)expression has been extracted.
(Inherited from XPRSprob.RowCreator.) |
|
Equals | (Inherited from Object.) |
|
FinishRow |
Tell this instance that all data for the current rows has been added. This calls
ConditionalCommit().
(Inherited from XPRSprob.RowCreator.) |
|
GetHashCode |
Serves as a hash function for a particular type.
(Inherited from Object.) |
|
GetPostfixExtractor |
Get a
IPostfixExtractor that can extract formulas into this
RowCreator.
(Inherited from XPRSprob.RowCreator.) |
|
GetRowCount |
Get the current row count, including buffered rows that are not yet committed.
(Inherited from XPRSprob.RowCreator.) |
|
GetType |
Gets the
Type of the current instance.
(Inherited from Object.) |
|
NormalizeCurrentRow |
Sort and merge duplicates in the current row. Must be called before FinishRow() is called.
(Inherited from XPRSprob.RowCreator.) |
|
SetName |
Set the name of the current row.
(Inherited from XPRSprob.RowCreator.) |
|
SetType |
Set the type of the current row.
(Inherited from XPRSprob.RowCreator.) |
|
StartExpression | (Inherited from XPRSprob.RowCreator.) |
|
ToString | (Inherited from Object.) |
|
Undo |
Undo all changes ever done by this instance. The creator should not be used after calling this function.
(Overrides XPRSprob.RowCreator.Undo().) |
