zorba::Sequence

#include <zorba/xquery_functions.h>

Provides a way for a function to return a sequence of some type T that can be iterated over.

T	The type of sequence.

Public Types

T	value_type

bool	next(value_type *result) Gets the next element in the sequence.
	Sequence(iterator *i) Constructs a new Sequence.
	Sequence(Sequence const &s) Copy constructs a Sequence.

operator=(Sequence const &)

T value_type

bool next(value_type *result)

Gets the next element in the sequence.

result

A pointer to the variable to receive the next element.

true only if there is a next element.

Sequence(iterator *i)

Constructs a new Sequence.

This constructor is intended only for function implementors.

i	The iterator that provides the elements of the sequence. Ownership of the iterator is taken.

Sequence(Sequence const &s)

Copy constructs a Sequence.

s	The Sequence to copy from. Note that it is a destructive copy in that the sequence of s is 'i' moved.

Sequence & operator=(Sequence const &)
