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.

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

- 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

- 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:

- 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.
