◆ canForwardIterate()

template<class Container >

template< class Container > bool QIterable< Container >::canForwardIterate ( ) const

inline

Returns whether it is possible to iterate over the container in forward direction.

This corresponds to the std::forward_iterator_tag iterator trait of the iterator and const_iterator of the container.

◆ canInputIterate()

template<class Container >

template< class Container > bool QIterable< Container >::canInputIterate ( ) const

inline

Returns whether the container has an input iterator.

This corresponds to the std::input_iterator_tag iterator trait of the iterator and const_iterator of the container.

Definition at line 449 of file qiterable.h.

References QIterable< Container >::m_metaContainer.

◆ canRandomAccessIterate()

template<class Container >

template< class Container > bool QIterable< Container >::canRandomAccessIterate ( ) const

inline

References QIterable< Container >::m_metaContainer.

◆ canReverseIterate()

template<class Container >

template< class Container > bool QIterable< Container >::canReverseIterate ( ) const
