slang::BumpAllocator class
#include <slang/util/BumpAllocator.h>

BumpAllocator - Fast O(1) allocator.

Allocates items sequentially in memory, with underlying memory allocated in blocks as needed. Individual items cannot be deallocated; the entire thing must be destroyed to release the memory.

Derived classes

template<typename T>
class TypedBumpAllocator
A strongly-typed version of the BumpAllocator, which has the additional behavior of calling destructors on all elements when the allocator itself is destructed.

A centralized location for creating and caching symbols.

Public functions

template<typename T, typename... Args>
auto emplace(Args && ... args) -> T*
Construct a new item using the allocator.
auto allocate(size_t size, size_t alignment) -> byte*
Allocate size bytes of memory with the given alignment.
void steal(BumpAllocator&& other)
Steals ownership of all of the memory contents of the given allocator.

Function documentation

template<typename T, typename... Args>
T* slang::BumpAllocator::emplace(Args && ... args)

Construct a new item using the allocator.

NOTE: the type of object being created must be trivially destructible, since the allocator won't run destructors when freeing memory.

void slang::BumpAllocator::steal(BumpAllocator&& other)

Steals ownership of all of the memory contents of the given allocator.

The other allocator will be in a moved-from state after the call.
