Public Member Functions
template<typename T >
T *	alloc (size_t size)
	Allocate an array of type T with length size. Data is zero initialized. No constructors of T are called.
template<typename T , typename... Args>
T *	allocAndInit (Args &&... args)
	Allocate a single entity of T and call the constructor with args.
void	ensureSize (size_t newSize)
void	free ()
	Free all allocated memory. No destructors are called. Stored pointers and resources need to be deallocated manually beforehand.
bool	isEmpty ()
	Returns true if no data is currently allocated.
	TemporaryMemory ()
	Constructor.
	TemporaryMemory (size_t initialSize)
	Constructor.

Static Public Attributes
static size_t constexpr	InitialDataSize = 4 * 1024 * 1024
	4 MiB of memory.

Detailed Description

Allocator for temporary used memory.

Can be used in places where memory is often allocated and deallocated. This reduces reduce the overhead of the system calls.

The initial memory is 4 MiB and can be extended with a call to ensureSize. All memory is initialized with zeros.

Member Function Documentation

ensureSize()

void codi::TemporaryMemory::ensureSize ( size_t  newSize )

inline

Ensures that enough space is available. Can only be called when no data has been allocated because reallocations invalidate pointers.
