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 If the range becomes invalid, the iterator is also no longer valid.

Since: Kanzi 3.9.0

Constructor & Destructor Documentation

◆ AbstractRangeIterator() [1/6]

kanzi::AbstractRangeIterator::AbstractRangeIterator ( )

explicitdefault

Default constructor.

Constructs an invalid iterator. Functions should not be called.

◆ AbstractRangeIterator() [2/6]

kanzi::AbstractRangeIterator::AbstractRangeIterator ( AbstractRangeLocationPtr location )

inlineexplicit

Constructor.

Parameters

location Range location.

◆ AbstractRangeIterator() [3/6]

kanzi::AbstractRangeIterator::AbstractRangeIterator ( AbstractIndexedRange & range )

inlineexplicit

Constructor.

Parameters

range Reference to an indexed range.

◆ AbstractRangeIterator() [4/6]

kanzi::AbstractRangeIterator::AbstractRangeIterator ( AbstractRange & range )

inlineexplicit

Constructor.

Parameters

range Range to iterate.

◆ AbstractRangeIterator() [5/6]

kanzi::AbstractRangeIterator::AbstractRangeIterator ( const AbstractRangeIterator & other )

inline

Copy constructor.

Parameters

other Source iterator.

◆ AbstractRangeIterator() [6/6]

kanzi::AbstractRangeIterator::AbstractRangeIterator ( AbstractRangeIterator && other )

inline

Move constructor.

Parameters

other Source iterator location.

Member Function Documentation

◆ getRange()

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.

◆ isValid()

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.

◆ advance()

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.

◆ getPropertyObject()

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.

◆ getPropertyValue()

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

propertyType	property type to access.
value	Variant to store the value to.

Returns: If a property value could be written to output value true, false otherwise.

◆ getValue()

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

inline

Access a value from a location.

If the iterator is not valid, results are undefined.

Parameters

value Variant to store the value to.

Returns: If value could be written true, false otherwise.

◆ operator bool()

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.

◆ operator==()

bool kanzi::AbstractRangeIterator::operator== ( const AbstractRangeIterator & rhs ) const

inline

Equals operator.

Parameters

rhs	Right-hand-side operand.

Returns: If iterators are equal, true, otherwise false.

◆ operator!=()

bool kanzi::AbstractRangeIterator::operator!= ( const AbstractRangeIterator & rhs ) const

inline

Not equals operator.

Parameters

rhs	Right-hand-side operand.

Returns: If iterators are equal, true, otherwise false.

◆ operator=() [1/2]

AbstractRangeIterator& kanzi::AbstractRangeIterator::operator= ( const AbstractRangeIterator & other )

inline

Copy operator.

Parameters

other Source object.

◆ operator=() [2/2]

AbstractRangeIterator& kanzi::AbstractRangeIterator::operator= ( AbstractRangeIterator && other )

inline

Move operator.

Parameters

other Source object.
