Detailed Description

The Iterator returned by DataSet::getIterator() that loops through the records.

Thanks to PHP5 SPL this allows you to foreach() over a DataSet: $ds = new QueryDataSet($conn, "select * from author"); $ds->fetchRecords(); foreach($ds as $rec) { print $rec->getValue("mycol"); }

Member Function Documentation

Iterator::__construct ( SQLiteResultSet $rs )

Construct the iterator. Parameters SQLiteResultSet  $rs

Iterator::rewind ( )

This method actually has no effect, since we do not rewind ResultSet for iteration.

Iterator::valid ( )

int Iterator::key ( )

Returns the cursor position. Note that this will not necessarily be 1 for the first row, since no rewind is performed at beginning of iteration. Returns int

array Iterator::current ( )

Returns the row (assoc array) at current cursor pos. Returns array

Iterator::next ( )

Advances internal cursor pos.

Iterator::__construct ( ResultSet $rs )

Construct the iterator. Parameters ResultSet  $rs

Iterator::rewind ( )

If not at start of resultset, this method will call seek(0). See also ResultSet::seek()

Iterator::valid ( )

This method checks to see whether there are more results by advancing the cursor position. See also ResultSet::next()

int Iterator::key ( )

Returns the cursor position. Returns int

array Iterator::current ( )

Returns the row (assoc array) at current cursor pos. Returns array

Iterator::next ( )

This method does not actually do anything since we have already advanced the cursor pos in valid(). See also valid()

Iterator::__construct ( DataSet $ds )

Iterator::rewind ( )

Iterator::valid ( )

Iterator::key ( )

Iterator::current ( )

Iterator::next ( )
