Detailed Description

template<uint32_t CapacityInBytes = 1024>
class gaia::mem::StackAllocator< CapacityInBytes >

Stack allocator capable of instantiating any default-constructible object on stack. Every allocation comes with a 16-bytes long sentinel object.

Member Function Documentation

◆ alloc()

template<uint32_t CapacityInBytes = 1024>
template<typename T >
GAIA_NODISCARD T * gaia::mem::StackAllocator< CapacityInBytes >::alloc ( uint32_t  cnt)
inline

Allocates.

Parameters
cntobjects of type
Template Parameters
Tinside the buffer. No default initialization is done so the object is returned in a non-initialized state unless a custom constructor is provided.
Returns
Pointer to the first allocated object

◆ free()

template<uint32_t CapacityInBytes = 1024>
void gaia::mem::StackAllocator< CapacityInBytes >::free ( void *  pData,
uint32_t  cnt 
)
inline

Frees the last allocated object from the stack.

Parameters
pDataPointer to the last allocated object on the stack
cntNumber of objects that were allocated on the given memory address
