DataProvider::AbstractDataProviderRecordIterator
Defines the abstract class for data provider iterators; the destructor releases the iterator.
Definition: AbstractDataProviderRecordIterator.qc.dox.h:33
DataProvider::DefaultRecordIterator
Default record iterator class for data providers that do not support custom read / search APIs.
Definition: DefaultRecordIterator.qc.dox.h:33
DataProvider::DefaultRecordIterator::constructor
constructor(AbstractIterator i, *hash< auto > where_cond, *hash< auto > search_options, *hash< string, AbstractDataField > record_type)
Returns an iterator for zero or more records matching the search options.
DataProvider::DefaultRecordIterator::valid
bool valid()
returns True if the iterator is currently pointing at a valid element, False if not
DataProvider::DefaultRecordIterator::memberGate
auto memberGate(string key)
Returns the value of the given field in the current record, if the iterator is valid.
DataProvider::DefaultRecordIterator::next
bool next()
Moves the current position to the next element; returns False if there are no more elements.
DataProvider::DefaultRecordIterator::getRecordType
*hash< string, AbstractDataField > getRecordType()
Returns the record description, if available.
DataProvider::DefaultRecordIterator::getValue
hash< auto > getValue()
returns a single record if the iterator is valid
