System::System

System(SysAllocBase* psysAlloc = SF_SYSALLOC_DEFAULT_CLASS::InitSystemSingleton());
System(const MemoryHeap::HeapDesc& rootHeapDesc, SysAllocBase* psysAlloc = SF_SYSALLOC_DEFAULT_CLASS::InitSystemSingleton());

Description

System initializes global heap for GFx objects. This method is called before any GFx objects are loaded. System has two versions of constructors, so that you can specify:

- No arguments; uses default system allocation and root heap.

- Custom SysAllocBase implementation with default root heap settings.

- Custom root heap settings with default SysAllocBase implementation.

- Both custom root heap settings and custom SysAllocBase implementation.

Parameters

Parameters	Description
SysAllocBase* psysAlloc = SF_SYSALLOC_DEFAULT_CLASS::InitSystemSingleton()	System allocator, SysAllocBase interface for allocating large block of memory.
const MemoryHeap::HeapDesc& rootHeapDesc	Heap descriptor MemoryHeap::HeapDesc for root heap created for all GFx object allocations.
