Detailed Description

Enables you to get the current node in relative path.

The functions in this class track the node changes in relative path by observing the changes in the Node::PathProperty properties. To get a node to which a relative path points, attach a resolver, and then get the node.

Member Enumeration Documentation

enum kanzi::RelativeNodeResolver::State

strong

Observing states.

Enumerator
Inactive	Inactive. Resolver is not attached.
Local	Observing the path changes of the node in the relative path.
Global	Observing changes to any path of any node. A resolver is in this state when there is no node in the relative path.

Constructor & Destructor Documentation

kanzi::RelativeNodeResolver::RelativeNodeResolver ( )

explicitdefault

Constructor.

Member Function Documentation

void kanzi::RelativeNodeResolver::attach	(	Node *	baseNode,
		string_view	relativePath
	)

Attaches a resolver.

When you attach a resolver, Kanzi starts observing the node changes in the node tree location to which the relative path points.

Parameters

baseNode	Node from which you want relative path to start.
relativePath	Relative path to the node tree location of which the resolver starts observing the changes.

void kanzi::RelativeNodeResolver::detach

(

)

Detaches a resolver.

When you detach a resolver, Kanzi stops observing the node changes in the node tree location to which the relative path points.

NodeSharedPtr kanzi::RelativeNodeResolver::get

(

)

const

Returns the node to which the relative path points.

Returns

The node to which the relative path points.

void kanzi::RelativeNodeResolver::resolve

(

)

Execute resolving.

RelativeNodeResolver::State kanzi::RelativeNodeResolver::getState ( ) const

inline

Returns the current observing state.

Returns

Current observing state.
