Luna::RHI::IBuffer

Represents one buffer resource that can be used to contain arbitrary binary data.

interface Luna::RHI::IBuffer : public virtual IResource

Base type

• IResource

Member functions

• virtual BufferDesc get_desc()=0

  Gets the descriptor of this buffer object.

• virtual RV map(usize read_begin, usize read_end, void **data)=0

  Maps the resource data to system memory and enables CPU access to the resource data. Map/unmap operations are reference counted, for each map operation, you need to call unmap once to finally unmap the memory.

• virtual void unmap(usize write_begin, usize write_end)=0

  Invalidates the pointer to the mapped data, and synchronizes changed data with device when needed. Map/unmap operations are reference counted, for each map operation, you need to call unmap once to finally unmap the memory.
