  • Constructor Details

    • FT_Memory

      public FT_Memory(ByteBuffer container)
      Creates a FT_Memory 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.

      public FT_Memory free$(@Nullable FT_Free_FuncI value)
      Sets the specified value to the free field.

    • realloc

      public FT_Memory realloc(@Nullable FT_Realloc_FuncI value)
      Sets the specified value to the realloc field.

    • set

      public FT_Memory set(long user, FT_Alloc_FuncI alloc, FT_Free_FuncI free$, FT_Realloc_FuncI realloc)
      Initializes this struct with the specified values.

      public FT_Memory set(FT_Memory src)
      Copies the specified struct data to this struct.
      Parameters:
      src - the source struct
      Returns:
      this struct
