Detailed Description

Abstract indexed range interface.

AbstractIndexedRange is intended as use for potential optimization to avoid creating iterators when accessing ranges that can be accessed by index. Its use is intended for internal Kanzi use to avoid casting to several range types offering access without range iterator interface.

Since: Kanzi 3.9.0

Member Function Documentation

size_t kanzi::AbstractIndexedRange::getSize ( )

inline

Gets the size of the indexed range.

Returns: Number of indices available.

PropertyObjectSharedPtr kanzi::AbstractIndexedRange::getPropertyObjectByIndex ( size_t index )

inline

Gets a property object by index.

Parameters

index Index of value to access.

Returns: Property object referenced by index if available, otherwise nullptr.

bool kanzi::AbstractIndexedRange::getPropertyValueByIndex	(	size_t	index,
		AbstractPropertyType	propertyType,
		Variant &	value
	)

inline

Access a property in a property object at an index.

Parameters

index	Index of value to access.
propertyType	property type to access.
value	Variant to store the value to.

Returns: If the index was valid and property object was available true, otherwise false.

bool kanzi::AbstractIndexedRange::getValueByIndex	(	size_t	index,
		Variant &	value
	)

inline

Reads a value by index and writes it to a variant.

Parameters

index	Index of value to access.
value	Variant to store the value to.

Returns: If value referenced by index existed and was written true, otherwise false.

bool kanzi::AbstractIndexedRange::adaptViewOverride	(	AbstractRange &	potentialViewRange,
