Member Function Documentation

operator IlsBoolean()

template<class RelationList >

IlsListRelationConstIterator< RelationList >::operator IlsBoolean

(

)

const

This conversion operator indicates whether the iterator has reached the end of the list.

It returns IlsFalse if the list is empty or if at least one unsuccessful extraction has been performed.

operator+()

template<class RelationList >

Position IlsListRelationConstIterator< RelationList >::operator+

(

int

i

)

const

Moves the iterator forward in the list according to the value supplied as its argument.

Exceptions

IlsEndOfList

If the iterator is moved past the last list item.

operator++() [1/2]

template<class RelationList >

Myself& IlsListRelationConstIterator< RelationList >::operator++

(

)

This increment operator moves the iterator to the next item in the list.

Exceptions

IlsEndOfList

If the iterator is moved past the last list item.

operator++() [2/2]

template<class RelationList >

Myself& IlsListRelationConstIterator< RelationList >::operator++

(

int

)

This operator is identical to operator++() except that it uses a prefix notation.

Exceptions

IlsEndOfList

If the iterator is moved past the last list item.

operator+=()

template<class RelationList >

Myself& IlsListRelationConstIterator< RelationList >::operator+=

(

int

i

)

Moves the iterator forward according to the value supplied as its argument.

Exceptions

IlsEndOfList

If the value provided moves the iterator past the last list item.

operator-()

template<class RelationList >

Position IlsListRelationConstIterator< RelationList >::operator-

(

int

i

)

const

Moves the iterator backward in the list according to the value supplied as its argument.

Exceptions

IlsBeginningOfList

If the iterator is moved past the first list item.

operator--() [1/2]

template<class RelationList >

Myself& IlsListRelationConstIterator< RelationList >::operator--

(

)

Moves the iterator to the previous item in the list.

Exceptions

IlsBeginningOfList

If the iterator is moved past the first list item.

operator--() [2/2]

template<class RelationList >

Myself& IlsListRelationConstIterator< RelationList >::operator--

(

int

)

This operator is identical to operator--() except that it uses a prefix notation.

Exceptions

IlsBeginningOfList

If the iterator is moved past the first list item.

operator-=()

template<class RelationList >

Myself& IlsListRelationConstIterator< RelationList >::operator-=

(

int

i

)

Moves the iterator backward in the list according to the value supplied as its argument.

Exceptions

IlsBeginningOfList

If the value provided moves the iterator past the first list item.

operator>>()

template<class RelationList >

Myself& IlsListRelationConstIterator< RelationList >::operator>>

(

TargetTypeP &

p

)

Sequentially reads the items in the list.

When the iterator is used for the first time, the item read is the one at the beginning of the list.

If the iterator has reached the last item in the list, and if the list is not empty, no value is assigned to the argument of the operator during the next read operation. The conversion operator to IlsBoolean returns IlsFalse (See operator IlsBoolean below).

If an iterator is built for an empty list, the conversion operator of the iterator returns IlsFalse.
