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

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
indexIndex 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
indexIndex of value to access.
propertyTypeproperty type to access.
valueVariant 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
indexIndex of value to access.
valueVariant to store the value to.
Returns
If value referenced by index existed and was written true, otherwise false.
