Definition: QC_HashListIterator.dox.h:38

Qore::HashListIterator::last
bool last()
returns True if on the last element of the list

Qore::HashListIterator::memberGate
auto memberGate(string key)
This method allows the iterator to be dereferenced directly as a hash for the current row being itera...

Qore::HashListIterator::empty
bool empty()
returns True if the result list is empty; False if not

Qore::HashListIterator::reset
reset()
Reset the iterator instance to its initial state.

Qore::HashListIterator::constructor
constructor(hash< auto > h)
Creates the hash list iterator object.

Qore::HashListIterator::next
bool next()
Moves the current position to the next element in the result list; returns False if there are no more...

Qore::HashListIterator::constructor
constructor()
Creates an empty hash list iterator object.

Qore::HashListIterator::max
int max()
returns the number of elements in the list

Qore::HashListIterator::prev
bool prev()
Moves the current position to the previous element in the result list; returns False if there are no ...

Qore::HashListIterator::getValue
hash< auto > getValue()
returns the current row value as a hash or throws an INVALID-ITERATOR exception if the iterator is in...

Qore::HashListIterator::getRow
hash< auto > getRow()
returns the current row value as a hash or throws an INVALID-ITERATOR exception if the iterator is in...

Qore::HashListIterator::valid
bool valid()
returns True if the iterator is currently pointing at a valid element, False if not

Qore::HashListIterator::getKeyValue
auto getKeyValue(string key)
Returns the current value for the column given as an argument.

Qore::HashListIterator::set
bool set(int pos)
sets the new position in the result list; if the position is invalid then the method returns False,...

Qore::HashListIterator::index
int index()
returns the current iterator position in the list or -1 if not pointing at a valid element

Qore::HashListIterator::copy
copy()
Creates a copy of the HashListIterator object, iterating the same object as the original and in the s...

Qore::HashListIterator::first
bool first()
