Detailed Description
template<typename T>
class LvArray::MallocBuffer< T >
Implements the Buffer interface using malloc and free.
- Template Parameters
-
T type of data that is contained in the buffer.
Both the copy constructor and copy assignment constructor perform a shallow copy of the source. Similarly the destructor does not free the allocation.
- Note
- The parent class bufferManipulation::VoidBuffer provides the default execution space related methods.

Constructor & Destructor Documentation
◆ MallocBuffer() [1/4]
|
inline |
Constructor for creating an empty or uninitialized buffer.
- Note
- An uninitialized MallocBuffer is equivalent to an empty MallocBuffer and does not need to be free'd.
Definition at line 51 of file MallocBuffer.hpp.
◆ MallocBuffer() [2/4]
|
inline |
Sized copy constructor, creates a shallow copy.
- Parameters
-
src The buffer to be coppied.
Definition at line 65 of file MallocBuffer.hpp.
◆ MallocBuffer() [3/4]
|
inline |
Move constructor, creates a shallow copy.
- Parameters
-
src The buffer to be moved from, is empty after the move.
Definition at line 74 of file MallocBuffer.hpp.
◆ MallocBuffer() [4/4]
|
inline |
Create a copy of src with const T.
- Template Parameters
-
_T A dummy parameter to allow enable_if, do not specify.
- Parameters
-
src The buffer to copy.
Definition at line 89 of file MallocBuffer.hpp.
Member Function Documentation
◆ capacity()
|
inline |
- Returns
- Return the capacity of the buffer.
Definition at line 157 of file MallocBuffer.hpp.
◆ data()
|
inline |
- Returns
- Return a pointer to the beginning of the buffer.
Definition at line 164 of file MallocBuffer.hpp.
◆ free()
|
inline |
Free the data in the buffer but does not destroy any values.
- Note
- To destroy the values and free the data call bufferManipulation::free.
Definition at line 146 of file MallocBuffer.hpp.
◆ operator=() [1/2]
|
inline |
Copy assignment operator, creates a shallow copy.
- Parameters
-
src The buffer to be copied.
- Returns
- *this.
Definition at line 100 of file MallocBuffer.hpp.
◆ operator=() [2/2]
|
inline |
Move assignment operator, creates a shallow copy.
- Parameters
-
src The buffer to be moved from, is empty after the move.
- Returns
- *this.
Definition at line 113 of file MallocBuffer.hpp.
◆ operator[]()
|
inline |
- Template Parameters
-
INDEX_TYPE the type used to index into the values.
- Returns
- The value at position
i.
- Parameters
-
i The position of the value to access.
- Note
- No bounds checks are performed.
Definition at line 175 of file MallocBuffer.hpp.
◆ reallocate()
|
inline |
Reallocate the buffer to the new capacity.
- Parameters
-
size The number of values that are initialized in the buffer. newCapacity The new capacity of the buffer.
