    Maps the specified portion of the given file into Memory for read operations with a ResourceScope.
    default Memory
    Memory.region(long offsetBytes, long capacityBytes)
    A region is a read-only view of this object.
    Memory
    Memory.region(long offsetBytes, long capacityBytes, ByteOrder byteOrder)
    A region is a read-only view of this object.
    static Memory
    Memory.wrap(byte[] array)
    Wraps the given primitive array for read operations assuming native byte order.
    static Memory
    Memory.wrap(byte[] array, int offsetBytes, int lengthBytes, ByteOrder byteOrder)
    Wraps the given primitive array for read operations with the given byte order.

    static Memory
    Memory.wrap(ByteBuffer byteBuffer)
    Provides a view of the given ByteBuffer for read-only operations.
    static Memory
    Memory.wrap(ByteBuffer byteBuffer, ByteOrder byteOrder)
