Constructor & Destructor Documentation

Bitmap()

operations_research::Bitmap::Bitmap ( uint32_t size, bool fill = false )

inlineexplicit

Constructor : This allocates on a uint32_t boundary. fill: true = initialize with 1's, false = initialize with 0's.

initialize all of the bits

Definition at line 42 of file bitmap.h.

~Bitmap()

operations_research::Bitmap::~Bitmap ( )

inline

Destructor: clean up.

Definition at line 51 of file bitmap.h.

Member Function Documentation

Clear()

void operations_research::Bitmap::Clear ( )

inline

Clears all bits in the bitmap.

Definition at line 77 of file bitmap.h.

Get()

bool operations_research::Bitmap::Get ( uint32_t index ) const

inline

Definition at line 58 of file bitmap.h.

Resize()

void operations_research::Bitmap::Resize	(	uint32_t	size,
		bool	fill = false )

Resizes the bitmap. If size < bits(), the extra bits will be discarded. If size > bits(), the extra bits will be filled with the fill value.

Todo

(user) : optimize next loop.

Definition at line 20 of file bitmap.cc.

Set()

void operations_research::Bitmap::Set ( uint32_t index, bool value )

inline

Definition at line 62 of file bitmap.h.

SetAll()

void operations_research::Bitmap::SetAll ( bool value )

inline

Sets all the bits to true or false.
