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.

Since:: 3.0, DALi version 1.0.0

Constructor & Destructor Documentation

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

Default constructor. Does not allocate space.

Since:: 3.0, DALi version 1.0.0

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

Destructor.

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

Since:: 3.0, DALi version 1.0.0

Member Function Documentation

SizeType Dali::VectorBase::Capacity ( ) const

Gets the capacity of this vector.

Since:: 3.0, DALi version 1.0.0

Returns:: The capacity of this vector

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

Copy a vector.

Since:: 3.0, DALi version 1.0.0

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:: 3.0, DALi version 1.0.0

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 it's needed frequently for Vector::End() iterator.

Since:: 3.0, DALi version 1.0.0

Returns:: The count of elements in this vector

bool Dali::VectorBase::Empty ( ) const

@ return if the vector is empty.

Since:: 3.0, DALi version 1.0.0

Returns:: True if the count of elements is empty

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

Erases an element.

Does not change capacity.

Since:: 3.0, DALi version 1.0.0

Parameters:

[in]	address	Address 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]`

Erases a range of elements.

Does not change capacity.

Since:: 3.0, DALi version 1.0.0

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 ( )

Releases the data.

Does not call destructors on objects held.

Since:: 3.0, DALi version 1.0.0

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 >.

Since:: 3.0, DALi version 1.0.0

Parameters:

[in]	count	Count of elements to reserve
[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::SetCount ( SizeType count ) [protected]

Helper to set the count.

Since:: 3.0, DALi version 1.0.0

Parameters:
