Detailed Description

Cached graph reads, monitors and caches connected graph starting from the given root node.

Only nodes that are reachable from the root node can ever be accessed.

This is built on top of cached nodes which on the other hand is built on top of node events. The cached graph has following features/limitations:

Single node can be child to multiple nodes
Root can only be removed if there is a cycle and then the node, that is parent for the root is removed

Member Function Documentation

CachedNodePtr Showcase::CachedGraph::getNode ( const NodeId & id ) const

This can return nullptr even if the requested node would be part of the graph (reachable from the root node).

This happens if the caching process hasn't yet reached the requested node.

This gives errors, find out why?

void Showcase::CachedGraph::startCaching ( )

Basically exists because shared_from_this can't be called on ctor
