Syntax

template<typename ElementType, uint32 Alignment>  
class TResourceArray :  
    public FResourceArrayInterface ,  
    public TArray< ElementType, TMemoryImageAllocator< DEFAULT_ALIGNMENT > >

Remarks

A array which allocates memory which can be used for UMA rendering resources. In the dynamically bound RHI, it isn't any different from the default array type, since none of the dynamically bound RHI implementations have UMA.
