delete

Member Function Documentation

◆ Clear()

void operations_research::glop::RowDeletionHelper::Clear ( )

Restores the class to its initial state.

RowDeletionHelper

Definition at line 301 of file preprocessor.cc.

◆ GetMarkedRows()

const DenseBooleanColumn & operations_research::glop::RowDeletionHelper::GetMarkedRows ( ) const

Returns a Boolean vector of the row to be deleted.

Definition at line 316 of file preprocessor.cc.

◆ IsEmpty()

bool operations_research::glop::RowDeletionHelper::IsEmpty ( ) const
inline

Returns true if no rows have been marked for deletion.

Definition at line 247 of file preprocessor.h.

◆ IsRowMarked()

bool operations_research::glop::RowDeletionHelper::IsRowMarked ( RowIndex row) const
inline

Returns whether or not the given row is marked for deletion.

Definition at line 262 of file preprocessor.h.

◆ MarkRowForDeletion()

void operations_research::glop::RowDeletionHelper::MarkRowForDeletion ( RowIndex row)

Adds a deleted row to the helper.

Definition at line 303 of file preprocessor.cc.

◆ operator=()

RowDeletionHelper & operations_research::glop::RowDeletionHelper::operator= ( const RowDeletionHelper & )
delete

◆ RestoreDeletedRows()

void operations_research::glop::RowDeletionHelper::RestoreDeletedRows ( ProblemSolution * solution) const

From a solution without the deleted rows, expand it by restoring the deleted rows to a VariableStatus::BASIC status with 0.0 value. This latter value is important, many preprocessors rely on it.

Copy the end of the vectors and swap them with the ones in solution.

Definition at line 320 of file preprocessor.cc.

◆ UnmarkRow()

void operations_research::glop::RowDeletionHelper::UnmarkRow ( RowIndex row)

If the given row was marked for deletion, unmark it.

Definition at line 311 of file preprocessor.cc.
