Constructor & Destructor Documentation

CuSubArray() [1/2]

CuSubArray ( const CuArrayBase< T > &  src, MatrixIndexT  offset, MatrixIndexT  dim  )

explicit

Constructor as a range of an existing CuArray or CuSubArray.

Note: like similar constructors in class CuVector and others, it can be used to evade 'const' constraints; don't do that.

Definition at line 315 of file cu-array-inl.h.

References data_, CuArrayBase< T >::data_, CuArrayBase< T >::Dim(), and KALDI_ASSERT.

                                            {
  KALDI_ASSERT(offset >= 0 && dim >= 0 &&
               offset + dim <= src.Dim());
  this->data_ = src.data_ + offset;
  this->dim_ = dim;
}

CuSubArray() [2/2]

CuSubArray ( const T *  data, MatrixIndexT  length  )

inline

Construct from raw pointers.

Definition at line 189 of file cu-array.h.

References CuArrayBase< T >::data_, and CuArrayBase< T >::dim_.

                                                 {
    // Yes, we're evading C's restrictions on const here, and yes, it can be used
    // to do wrong stuff; unfortunately the workaround would be very difficult.
    this->data_ = const_cast<T*>(data);
    this->dim_ = length;
  }
