    • Constructor Detail

      • XXH64Canonical

        public XXH64Canonical​(java.nio.ByteBuffer container)
        Creates a XXH64Canonical instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.

        Returns a ByteBuffer view of the digest field.
      • digest

        public byte digest​(int index)
        Returns the value at the specified index of the digest field.
      • malloc

        public static XXH64Canonical malloc()
        Returns a new XXH64Canonical instance allocated with memAlloc. The instance must be explicitly freed.
      • calloc

        public static XXH64Canonical calloc()
        Returns a new XXH64Canonical instance allocated with memCalloc. The instance must be explicitly freed.
      • create

        public static XXH64Canonical create​(long address)
        Returns a new XXH64Canonical instance for the specified memory address.
      • createSafe

        @Nullable
        public static XXH64Canonical createSafe​(long address)
        Like create, but returns null if address is NULL.
      • create

        public static XXH64Canonical.Buffer create​(long address,

        Create a XXH64Canonical.Buffer instance at the specified memory.
        Parameters:
        address - the memory address
        capacity - the buffer capacity
      • createSafe

        @Nullable
        public static XXH64Canonical.Buffer createSafe​(long address,
                                                       int capacity)
        Like create, but returns null if address is NULL.
