makVrv::DtReservedElementsBuffer< T > Class Template Reference

template<typename T>
class makVrv::DtReservedElementsBuffer< T >

Template class which implements a data structure providing management of 'reserved' elements. The data structure is a wrapper around std::vector - adding a reserved flag for elements in the std::vector. The implementation still keeps the values in the buffer contiguous in memory.

Constructor & Destructor Documentation

template<typename T>

makVrv::DtReservedElementsBuffer< T >::DtReservedElementsBuffer	(	size_t	initialSize,
		size_t	growIncrement,
		const T &	defaultValue
	)

Constructs a reserved elements buffer.

Parameters

initialSize	The initial number of elements the buffer will have.
growIncrement	The amount of elements to grow the buffer whenever growth is needed.

template<typename T>

makVrv::DtReservedElementsBuffer< T >::~DtReservedElementsBuffer

(

)

Member Function Documentation

template<typename T>

size_t makVrv::DtReservedElementsBuffer< T >::reserveElements

(

size_t

elementsToReserve

)

Reserve some number of contiguous elements in the buffer.

Parameters

elementsToReserve

The number of contiguous elements to reserve.

Returns

The index of the first element that was reserved.

template<typename T>

void makVrv::DtReservedElementsBuffer< T >::freeElements	(	size_t	startIndex,
		size_t	numberOfElements
	)

Free some number of contiguous elements in the buffer.

Parameters

startIndex	The index of the first element to free up.
numberOfElements	The number of elements to free starting at the provided start index.

Note

Freed element values are reset to the provided default value for elements.
