    • resize

      public DogArray_I32 resize(int size)
      Description copied from interface: DogArrayPrimitive

      Ensures that the internal array is at least this size. Value of elements previously in the array will not be changed. If the size is increased then the value of new elements in undefined.

      If you wish to resize the array and avoid copying over past values for performance reasons, then you must either resize(0) or call DogArrayPrimitive.reset() first.
      Specified by:
      resize in interface DogArrayPrimitive<DogArray_I32>
      Parameters:
      size - desired new size

    • resize

      public DogArray_I32 resize(int size, int value)
      Resizes the array and assigns the default value to every new element.
      Parameters:
      size - New size
      value - Default value

    • resetResize

      @Deprecated public void resetResize(int size, int value)
      Deprecated.
      Convenience function that will first call reset() then resize(int, int), ensuring that every element in the array will have the specified value
      Parameters:
      size - New size
      value - New value of every element

    • resize

      public void resize(int size, DogLambdas.AssignIdx_I32 op)
      Resizes and assigns the new elements (if any) to the value specified by the lambda
      Parameters:
      size - New sie
      op - Assigns default values

    • fill

    • extend

      public void extend(int size)

      public void reserve(int amount)
      Description copied from interface: DogArrayPrimitive
