This tutorial shows the use of NodeHandle namespaces.
Each NodeHandle can be assigned a namespace the same way every node can be assigned a namespace (this is usually done through the environment variable ROS_NAMESPACE).
A namespace per NodeHandle allows you to separate different pieces of your application into different namespaces.
This prints /level1/a
If another NodeHandle is provided as the first argument to the constructor, it uses that NodeHandle's namespace as a parent namespace. Therefore, this NodeHandle will be in the /level1/level2 namespace.
This prints /level1/level2/a
Accessing private names (inside the nodes' name) is possible by creating a NodeHandle whose name starts with a tilde (~).
This prints /node_handle_namespaces/a
