Detailed Description

template<typename T>
class LocARNA::SparseVector< T >::element

Element of sparse vector.

Proxy for sparse vector entries. This is required for non-const access to vector elements in order to provide a very similar syntax for the sparse data structure and the corresponding non-sparse vector.

Constructor & Destructor Documentation

template<typename T>

LocARNA::SparseVector< T >::element::element ( SparseVector< T > *  m, key_t  k  )

inline

Construct as proxy for specified element in given sparse vector.

Parameters

m	pointer to sparse vector
k	key/index of entry in given sparse vector

Member Function Documentation

template<typename T>

LocARNA::SparseVector< T >::element::operator value_t ( )

inline

Access entry for which the class acts as proxy.

Returns

value of vector entry.

If entry does not exist, return the default value

template<typename T>

element LocARNA::SparseVector< T >::element::operator+= ( const value_t &  x )

inline

Operator for in place addition.

Parameters

x

value

Postcondition

x is added to vector entry for that the class is proxy

Returns

*this after adding x

Note

If entry does not exist, x is added to the default value

template<typename T>

element& LocARNA::SparseVector< T >::element::operator= ( const value_t &  x )

inline

Assignment operator.

Parameters

x

value

Postcondition

x is assigned to vector entry for that the class is proxy

Returns

*this after assigning x

Note

If x equals the default value and the entry exists, it is erased
