Detailed Description

Structure that represents a set of strings as iterator.

Constructor & Destructor Documentation

virtual strus::ValueIteratorInterface::~ValueIteratorInterface ( )

inlinevirtual

virtual std::vector<std::string> strus::ValueIteratorInterface::fetchValues ( std::size_t maxNofElements )

pure virtual

Fetch the next N elements.

Parameters

[in] maxNofElements maximum number of elements to fetch

Note: the iterator position is on the element following the last element returned or at EOF

virtual void strus::ValueIteratorInterface::skip	(	const char *	value,
		std::size_t	size
	)

pure virtual

Set the next key to find.

Parameters

[in]	value	pointer key string to seek
[in]	size	sizeof of value in bytes

virtual void strus::ValueIteratorInterface::skipPrefix	(	const char *	value,
		std::size_t	size
	)

pure virtual

Set the next key to find with the condition that all elements fetched contain the key specified as prefix.

Parameters

[in]	value	pointer key string to seek
[in]	size	sizeof of value in bytes
