Public Member Functions
	Base_swap ()
	Default constructor.
	Base_swap (unsigned int numberOfColumns)
	As default constructor, but reserves spaces for numberOfColumns columns.
	Base_swap (const Base_swap &matrixToCopy)
	Copy constructor.
	Base_swap (Base_swap &&other) noexcept
	Move constructor.
void	swap_columns (index columnIndex1, index columnIndex2)
	Swaps the two columns at given indices in the column container. Does not updates the column index value, potentially stored in the cells. This will be done when calling _orderRows().
void	swap_rows (id_index rowIndex1, id_index rowIndex2)
	Swaps the two rows at the given indices, but in a lazy manner. That is, the swap is registered but not executed. The reordering will be done when calling _orderRows().
Base_swap &	operator= (Base_swap other)
	Assign operator.

Friends
void	swap (Base_swap &base1, Base_swap &base2)
	Swap operator.

Constructor & Destructor Documentation

Base_swap() [1/3]

template<class Master_matrix , class Base_matrix >

Gudhi::persistence_matrix::Base_swap< Master_matrix, Base_matrix >::Base_swap ( unsigned int  numberOfColumns )

inline

As default constructor, but reserves spaces for numberOfColumns columns.

Parameters

numberOfColumns

Number of columns to reserve space for.

Base_swap() [2/3]

template<class Master_matrix , class Base_matrix >

Gudhi::persistence_matrix::Base_swap< Master_matrix, Base_matrix >::Base_swap

(

const Base_swap< Master_matrix, Base_matrix > &

matrixToCopy

)

Copy constructor.

Parameters

matrixToCopy

Matrix to copy.

Base_swap() [3/3]

template<class Master_matrix , class Base_matrix >

Gudhi::persistence_matrix::Base_swap< Master_matrix, Base_matrix >::Base_swap ( Base_swap< Master_matrix, Base_matrix > &&  other )

noexcept

Move constructor.

Parameters

other

Matrix to move.

Member Function Documentation

swap_columns()

template<class Master_matrix , class Base_matrix >

void Gudhi::persistence_matrix::Base_swap< Master_matrix, Base_matrix >::swap_columns ( index  columnIndex1, index  columnIndex2  )

inline

Swaps the two columns at given indices in the column container. Does not updates the column index value, potentially stored in the cells. This will be done when calling _orderRows().

Parameters

columnIndex1	First MatIdx column index.
columnIndex2	Second MatIdx column index.

swap_rows()

template<class Master_matrix , class Base_matrix >

void Gudhi::persistence_matrix::Base_swap< Master_matrix, Base_matrix >::swap_rows ( id_index  rowIndex1, id_index  rowIndex2  )

inline

Swaps the two rows at the given indices, but in a lazy manner. That is, the swap is registered but not executed. The reordering will be done when calling _orderRows().

Parameters

rowIndex1	First row index.
rowIndex2	Second row index.
