## Detailed Description

template<typename data_t>
class uhd::experts::data_node_t< data_t >

class data_node_t

The data node class hold a passive piece of data in the expert graph. A data node is clean if its underlying data is clean. Access to the underlying data is provided using two methods:

1. Special accessor classes (for R/W enforcement)
2. External clients (via commit and retrieve). This access is protected by the callback mutex.

Requirements for data_t

- Must have a default constructor
- Must have a copy constructor
- Must have an assignment operator (=)

## - Must have an equality operator (==)
