Member Function Documentation

§ at()

template<typename _Scalar, typename _Index>
Scalar Eigen::internal::CompressedStorage< _Scalar, _Index >::at ( Index  key,
const Scalar &  defaultValue = Scalar(0) 
) const
inline
Returns
the stored value at index key If the value does not exist, then the value defaultValue is returned without any insertion.

§ atWithInsertion()

template<typename _Scalar, typename _Index>
Scalar& Eigen::internal::CompressedStorage< _Scalar, _Index >::atWithInsertion ( Index  key,
const Scalar &  defaultValue = Scalar(0) 
)
inline
Returns
a reference to the value at index key If the value does not exist, then the value defaultValue is inserted such that the keys are sorted.

§ searchLowerIndex() [1/2]

template<typename _Scalar, typename _Index>
Index Eigen::internal::CompressedStorage< _Scalar, _Index >::searchLowerIndex ( Index  key) const
inline
Returns
the largest k such that for all j in [0,k) index[j]<key

§ searchLowerIndex() [2/2]

template<typename _Scalar, typename _Index>
Index Eigen::internal::CompressedStorage< _Scalar, _Index >::searchLowerIndex ( size_t  start,
size_t  end,
Index  key 
) const
inline
Returns
the largest k in [start,end) such that for all j in [start,k) index[j]<key
