Detailed Description

Iterator is an range that references a location in another range.

Iterator range combines a weak reference to another range and an iterator to that range. There is only one readable value, which is the current iteration location.

Evaluating the iterator range yields a new iterator range that advances the iterator one step. If the iteration has already reached the end of the source range, the evaluation returns a shared pointer to the same range (the same as default result of range evaluation).

Since: Kanzi 3.9.0

sourceIterator Iterator to another range.

Member Function Documentation

◆ create() [1/3]

static IteratorRangeSharedPtr kanzi::IteratorRange::create ( AbstractRangeSharedPtr sourceRange )

static

Creates a new iterator range.

Parameters

sourceRange Range to iterate.

Returns: Iterator range shared pointer.

◆ create() [2/3]

static IteratorRangeSharedPtr kanzi::IteratorRange::create ( const AbstractRangeIterator & sourceIterator )

static

Creates a new iterator range.

Parameters

sourceIterator Source iterator to advance.

Returns: Iterator range shared pointer.

◆ create() [3/3]

static IteratorRangeSharedPtr kanzi::IteratorRange::create ( AbstractRangeIterator && sourceIterator )

static

Creates a new iterator range.

Parameters

sourceIterator Source iterator to advance.

Returns: Iterator range shared pointer.

◆ getPropertyObject()

PropertyObjectSharedPtr kanzi::IteratorRange::getPropertyObject ( )

inline

Gets a property object from the current iterator location.

Returns: Property object at current location or nullptr

◆ getPropertyValue()

bool kanzi::IteratorRange::getPropertyValue	(	AbstractPropertyType	propertyType,
		Variant &	value )

inline

Gets a property value from the property object at current location.

Parameters

propertyType	Property type to acquire.
value	Variant to store the value into.

Returns: If a property value was extracted, true, otherwise false.

◆ getValue()

bool kanzi::IteratorRange::getValue ( Variant & value )

inline

Gets the value at current location.

Parameters

value Variant to store the value into.

Returns: If a value was extracted, true, otherwise false.

◆ adapt()

void kanzi::IteratorRange::adapt ( AbstractRange & range )

inline

Adapt another range.

This function is used internally by Kanzi to reuse an IteratorRange as opposed to creating a new one.

Parameters

range Range to adapt.

		AbstractPropertyType	propertyType,
		Variant &	value )

overrideprotectedvirtual

AbstractIndexedRange::getPropertyValueByIndexOverride() implementation.

Implements kanzi::AbstractIndexedRange.

◆ getValueByIndexOverride()

Member Data Documentation

◆ m_iter

AbstractRangeIterator kanzi::IteratorRange::m_iter

protected

Iterator into a source range.

◆ m_sourceRangeReference

AbstractRangeSharedPtr kanzi::IteratorRange::m_sourceRangeReference

protected

Reference to the source range.

AbstractRangeIterator does not hold a reference to the source range, so it falls to the IteratorRange.
