Interface MemoryBackend

public interface MemoryBackend
Instances of this interface provide direct/unsafe off-heap memory access.

Use Configuration.MEMORY_BACKEND to configure or override the memory backed used by LWJGL.

LWJGL does not guarantee API stability for this interface.

  • Method Details

    • getDefaultInstance

      static MemoryBackend getDefaultInstance()
      Returns the default MemoryBackend instance.
