Typedef Documentation

BumpPtrAllocator

typedef BumpPtrAllocatorImpl BumpPtrAllocator

The standard BumpPtrAllocator which just uses the default template parameters.

Function Documentation

alignAddr()

uintptr_t alignAddr ( const void *  Addr, size_t  Alignment  )

inline

Aligns Addr to Alignment bytes, rounding up.

Alignment should be a power of two. This method rounds up, so alignAddr(7, 4) == 8 and alignAddr(8, 4) == 8.

alignmentAdjustment()

size_t alignmentAdjustment ( const void *  Ptr, size_t  Alignment  )

inline

Returns the necessary adjustment for aligning Ptr to Alignment bytes, rounding up.

isPowerOf2_64()

constexpr bool isPowerOf2_64 ( uint64_t  Value )

inlineconstexpr

Return true if the argument is a power of two > 0 (64 bit edition.)

NextPowerOf2()

uint64_t NextPowerOf2 ( uint64_t  A )

inline

Returns the next power of two (in 64-bits) that is strictly greater than A. Returns zero on overflow.

operator delete()

template<size_t SlabSize, size_t SizeThreshold>

void operator delete	(	void *	,
		BumpPtrAllocatorImpl< SlabSize, SizeThreshold > &
	)

operator new()

template<size_t SlabSize, size_t SizeThreshold>

void* operator new	(	size_t	Size,
		BumpPtrAllocatorImpl< SlabSize, SizeThreshold > &	Allocator
	)
