    • resize

      public DogArray_F32 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_F32>
      Parameters:
      size - desired new size
      Returns:
      Returns 'this' to allow chaining of operations.

      value - Default value

    • resetResize

      @Deprecated public void resetResize(int size, float value)

      Parameters:
      size - New size
      value - New value of every element

    • resize

      public DogArray_F32 resize(int size, DogLambdas.AssignIdx_F32 op)
