Member Function Documentation

alloc()

virtual void* G3D::MemoryManager::alloc ( size_t  s )

virtual

Return a pointer to s bytes of memory that are unused by the rest of the program.

The contents of the memory are undefined

Reimplemented in G3D::BufferUnmapper, G3D::CRTMemoryManager, G3D::AreaMemoryManager, and G3D::AlignedMemoryManager.

create()

static shared_ptr<MemoryManager> G3D::MemoryManager::create ( )

static

Return the instance.

There's only one instance of the default MemoryManager; it is cached after the first creation.

Referenced by G3D::Array< G3D::AABox >::Array(), G3D::categorizeByDerivedType(), and G3D::Table< String, double >::Table().

createShared()

template<class T , class ... ArgTypes>

static shared_ptr<T> G3D::ReferenceCountedObject::createShared ( ArgTypes &&...  args )

inlinestaticprotectedinherited

Like std::make_shared, but works for protected constructors.

Call as createShared<myclass>.

free()

virtual void G3D::MemoryManager::free ( void *  ptr )

virtual

Invoke to declare that this memory will no longer be used by the program.

The memory manager is not required to actually reuse or release this memory.

Reimplemented in G3D::BufferUnmapper, G3D::CRTMemoryManager, G3D::AreaMemoryManager, and G3D::AlignedMemoryManager.

isThreadsafe()

virtual bool G3D::MemoryManager::isThreadsafe ( ) const

virtual

Returns true if this memory manager is threadsafe (i.e., alloc and free can be called asychronously)

Reimplemented in G3D::BufferUnmapper, G3D::CRTMemoryManager, G3D::AreaMemoryManager, and G3D::AlignedMemoryManager.
