Detailed Description

Base interface for nodes that can be evaluated (executed).

Evaluatable nodes perform actions and return a shell_status indicating the result of execution.

Constructor & Destructor Documentation

shell_node_evaluable()

bs::shell_node_evaluable::shell_node_evaluable ( const shell_node_type  nType, const std::size_t  nPos  )

inline

Construct an evaluable node.

Parameters

nType	Node type.
nPos	Node position.

Member Function Documentation

evaluate()

virtual shell_status bs::shell_node_evaluable::evaluate ( shell_session &  oSession ) const

pure virtual

Evaluate (execute) the node.

Parameters

oSession
