Detailed Description

template<typename MetaObject, class Iterator>
class lagoon::range_base< MetaObject, Iterator >

The base template for the implementation of ranges.

This is a more flexible variant of the range<> template, allowing to specify the underlying item container to traverse.

Constructor & Destructor Documentation

template<typename MetaObject, class Iterator>

lagoon::range_base< MetaObject, Iterator >::range_base	(	const iterator &	b,
		const iterator &	e
	)		[inline]

Constructor taking two iterators.

this constructor should NOT be used directly. Ranges are instantiated by Lagoon's internal code.

template<typename MetaObject, class Iterator>

size_t lagoon::range_base< MetaObject, Iterator >::leap_front

(

size_t

leap

)

[inline]

Moves the front of the range n items forward.

This member function moves the front of the range leap items forward. The leap parameter may be greater than size() resulting in an empty range. Returns the number of items actually leaped through.
