Detailed Description

Abstract range iterator interface.

Range iterators are value types, so the virtual access to the range is implemented through range location. If the range becomes invalid, the iterator is also no longer valid.

Constructor & Destructor Documentation

kanzi::AbstractRangeIterator::AbstractRangeIterator ( )
explicitdefault

Default constructor.

Constructs an invalid iterator. Functions should not be called.

kanzi::AbstractRangeIterator::AbstractRangeIterator ( AbstractRangeLocationPtr  location)
inlineexplicit

Constructor.

Parameters
locationRange location.
kanzi::AbstractRangeIterator::AbstractRangeIterator ( AbstractIndexedRange range)
inlineexplicit

Constructor.

Parameters
rangeReference to an indexed range.
kanzi::AbstractRangeIterator::AbstractRangeIterator ( AbstractRange range)
inlineexplicit

Constructor.

Parameters
rangeRange to iterate.
kanzi::AbstractRangeIterator::AbstractRangeIterator ( const AbstractRangeIterator other)
inline

Copy constructor.

Parameters
otherSource iterator.
kanzi::AbstractRangeIterator::AbstractRangeIterator ( AbstractRangeIterator &&  other)
inlinenoexcept

Move constructor.

Parameters
otherSource iterator location.

Member Function Documentation

AbstractRange* kanzi::AbstractRangeIterator::getRange ( ) const
inline

Accesses the shared range being iterated.

Only returns a meaningful pointer if the iterator is valid.

Returns
Pointer to iterated range.
bool kanzi::AbstractRangeIterator::isValid ( ) const
inline

Indicates whether the iterator is valid.

If the location has not been set, an iterator is not valid. A iterator is valid if it's not at the end of iteration and can be read.

Returns
If the location is valid, true, false otherwise.
bool kanzi::AbstractRangeIterator::advance ( )
inline

Advances the iterator.

If the iterator was valid before advance() was called, it always increments. The return value only depends on whether the iterator is readable post the increment.

Returns
True if iterator was both advanced and is still readable.
PropertyObjectSharedPtr kanzi::AbstractRangeIterator::getPropertyObject ( )
inline

Access to a property object at the iterator location.

If the iterator is not valid, results are undefined.

Returns
Property object at location or nullptr.
bool kanzi::AbstractRangeIterator::getPropertyValue ( AbstractPropertyType  propertyType,
Variant value 
)
inline

Access a property at the iterator location.

If the iterator is not valid, results are undefined.

Parameters
propertyTypeproperty type to access.
valueVariant to store the value to.
Returns
If a property value could be written to output value true, false otherwise.
bool kanzi::AbstractRangeIterator::getValue ( Variant value)
inline

Access a value from a location.

If the iterator is not valid, results are undefined.

Parameters
valueVariant to store the value to.
Returns
If value could be written true, false otherwise.
kanzi::AbstractRangeIterator::operator bool ( ) const
inline

Operator for checking if the iterator has been initialized.

move() from an AbstractRangeIterator makes it uninitialized.

Returns
If the iterator is valid, true, otherwise false.
bool kanzi::AbstractRangeIterator::operator== ( const AbstractRangeIterator rhs) const
inline

Equals operator.

Parameters
rhsRight-hand-side operand.
Returns
If iterators are equal, true, otherwise false.
bool kanzi::AbstractRangeIterator::operator!= ( const AbstractRangeIterator rhs) const
inline

Not equals operator.

Parameters
rhsRight-hand-side operand.
Returns
If iterators are equal, true, otherwise false.
AbstractRangeIterator& kanzi::AbstractRangeIterator::operator= ( const AbstractRangeIterator other)
inline

Copy operator.

Parameters
otherSource object.
AbstractRangeIterator& kanzi::AbstractRangeIterator::operator= ( AbstractRangeIterator &&  other)
inlinenoexcept

Move operator.

Parameters
otherSource object.
