class StdAllocator
 

Detailed Description

template<typename T>
class open3d::core::StdAllocator< T >

Class satisfying the Allocator requirements defined by the C++ standard. This bridge makes the MemoryManager interface accessible to all classes and containers that use the standard Allocator interface.

This is particularly useful to allocate (potentially cached) GPU memory or different types of memory depending on the provided device.
