Member Function Documentation

Allocate()

virtual void * TempAllocatorImpl::Allocate ( uint inSize )

inlineoverridevirtual

Implements TempAllocator.

CanAllocate()

bool TempAllocatorImpl::CanAllocate ( uint inSize ) const

inline

Check if an allocation of inSize can be made in this fixed buffer allocator.

Free()

virtual void TempAllocatorImpl::Free ( void * inAddress, uint inSize )

inlineoverridevirtual

Frees inSize bytes of memory located at inAddress.

Implements TempAllocator.

GetSize()

size_t TempAllocatorImpl::GetSize ( ) const

inline

Get the total size of the fixed buffer.

GetUsage()

size_t TempAllocatorImpl::GetUsage ( ) const

inline

Get current usage in bytes of the buffer.

IsEmpty()

bool TempAllocatorImpl::IsEmpty ( ) const

inline

Check if no allocations have been made.

OwnsMemory()

bool TempAllocatorImpl::OwnsMemory ( const void * inAddress ) const

inline

Check if memory block at inAddress is owned by this allocator.
