Detailed Description

template<typename T, xiiUInt32 SizeInBytes>
struct xiiDataBlock< T, SizeInBytes >

Copyright (c) Theophilus Eriata. All Rights Reserved.

Represents a typed block of memory with fixed size, typically used for bulk allocations.

This wrapper provides type-safe access to a block of memory that can hold multiple elements of type T. The block has a fixed capacity determined by SizeInBytes and sizeof(T). It tracks the current count of used elements and provides stack-like operations for efficient allocation/deallocation within the block.

Member Function Documentation

PopBack()

template<typename T, xiiUInt32 SizeInBytes>

XII_FORCE_INLINE T * xiiDataBlock< T, SizeInBytes >::PopBack

(

)

Removes and returns pointer to the last element in the block.

Returns nullptr if the block is empty.

ReserveBack()

template<typename T, xiiUInt32 SizeInBytes>

XII_FORCE_INLINE T * xiiDataBlock< T, SizeInBytes >::ReserveBack

(

)

Reserves space for one element at the end of the block.

Returns pointer to the reserved element, or nullptr if the block is full.
