Detailed Description

Base class to handle the memory of simple vector.

Memory layout is such that it has two std::size_t to hold the count and capacity of the vector. VectorBase::mData is adjusted so that it points to the beginning of the first real item so that iterating the items is quick.

Member Typedef Documentation

typedef std::size_t Dali::VectorBase::SizeType

Size type.

Since :: 2.4

Reimplemented in Dali::Vector< T, IsTrivialType >, Dali::Vector< SlotConnection * >, Dali::Vector< SignalConnection * >, Dali::VectorAlgorithms< IsTrivial >, Dali::VectorAlgorithms< TypeTraits< SlotConnection * >::IS_TRIVIAL_TYPE==true >, Dali::VectorAlgorithms< IsTrivialType >, and Dali::VectorAlgorithms< TypeTraits< SignalConnection * >::IS_TRIVIAL_TYPE==true >.

Constructor & Destructor Documentation

Dali::VectorBase::VectorBase ( ) [protected]

Default constructor. Does not allocate space.

Since :: 2.4

Dali::VectorBase::~VectorBase ( ) [protected]

Destructor.

Does not release the space. Derived class needs to call Release. Not virtual as should not be called directly and we do not want a vtable for this class as it would unnecessarily increase size.

Since :: 2.4

Member Function Documentation

SizeType Dali::VectorBase::Capacity ( ) const

Gets the capacity of this vector.

Since :: 2.4

Returns:: The capacity of this vector.

void Dali::VectorBase::Copy	(	const VectorBase &	vector,
		SizeType	elementSize
	)		`[protected]`

Copy a vector.

Since :: 2.4

Parameters:

[in]	vector	Vector to copy from.
[in]	elementSize	Size of a single element.

Reimplemented in Dali::VectorAlgorithms< IsTrivial >, Dali::VectorAlgorithms< TypeTraits< SlotConnection * >::IS_TRIVIAL_TYPE==true >, Dali::VectorAlgorithms< IsTrivialType >, and Dali::VectorAlgorithms< TypeTraits< SignalConnection * >::IS_TRIVIAL_TYPE==true >.

void Dali::VectorBase::CopyMemory	(	char *	destination,
		const char *	source,
		size_t	numberOfBytes
	)		`[protected]`

Copies a number of bytes from source to destination.

source and destination must not overlap.

Since :: 2.4

Parameters:

[in]	destination	Pointer to the destination address.
[in]	source	Pointer to the source address.
[in]	numberOfBytes	The number of bytes to be copied.

SizeType Dali::VectorBase::Count ( ) const

This method is inlined as its needed frequently for Vector::End() iterator.

Since :: 2.4

Returns:: The count of elements in this vector.

void Dali::VectorBase::Erase	(	char *	address,
		SizeType	elementSize
	)		`[protected]`

Erase an element.

Does not change capacity.

Since :: 2.4

Parameters:

[in]	address	Adress to erase from.
[in]	elementSize	Size to erase.

Precondition:: Last element cannot be erased as there is nothing to move.

Reimplemented in Dali::VectorAlgorithms< IsTrivial >, Dali::VectorAlgorithms< TypeTraits< SlotConnection * >::IS_TRIVIAL_TYPE==true >, Dali::VectorAlgorithms< IsTrivialType >, and Dali::VectorAlgorithms< TypeTraits< SignalConnection * >::IS_TRIVIAL_TYPE==true >.

char* Dali::VectorBase::Erase	(	char *	first,
		char *	last,
		SizeType	elementSize
	)		`[protected]`

Erase a range of elements.

Does not change capacity.

Since :: 2.4

Parameters:

[in]	first	Address to the first element to be erased.
[in]	last	Address to the last element to be erased.
[in]	elementSize	Size of one of the elements to be erased.

Returns:: Address pointing to the next element of the last one.

Reimplemented in Dali::VectorAlgorithms< IsTrivial >, Dali::VectorAlgorithms< TypeTraits< SlotConnection * >::IS_TRIVIAL_TYPE==true >, Dali::VectorAlgorithms< IsTrivialType >, and Dali::VectorAlgorithms< TypeTraits< SignalConnection * >::IS_TRIVIAL_TYPE==true >.

void Dali::VectorBase::Release ( )

Release the data.

Does not call destructors on objects held.

Since :: 2.4

Reimplemented in Dali::Vector< T, IsTrivialType >, Dali::Vector< SlotConnection * >, Dali::Vector< SignalConnection * >, Dali::VectorAlgorithms< IsTrivial >, Dali::VectorAlgorithms< TypeTraits< SlotConnection * >::IS_TRIVIAL_TYPE==true >, Dali::VectorAlgorithms< IsTrivialType >, and Dali::VectorAlgorithms< TypeTraits< SignalConnection * >::IS_TRIVIAL_TYPE==true >.

void Dali::VectorBase::Reserve	(	SizeType	count,
		SizeType	elementSize
	)		`[protected]`

Reserve space in the vector.

Since :: 2.4

Parameters:

[in]	count	Count of elements to reserve.
[in]	elementSize	Size of a single element.

Helper to set the count.

Since :: 2.4

Parameters:

[in] count Number of elements in the vector.

SizeType Dali::VectorBase::Size ( ) const
