Detailed Description

Wraps a command expression and executes it as a command.

The command expression is an expandable node that will be expanded into argument tokens and then executed according to shell semantics.

Constructor & Destructor Documentation

shell_node_command()

bs::shell_node_command::shell_node_command ( std::unique_ptr< shell_node_command_expression > &&  pCommand )

explicit

Construct a command node.

Exceptions

shell_node_invalid_argument

If expression is null.

Parameters

pCommand

Owned command expression.

Member Function Documentation

evaluate()

shell_status bs::shell_node_command::evaluate ( shell_session &  oSession ) const

overridevirtual

Evaluate (execute) the command expression.

Parameters

oSession

Returns

shell_status Result of command execution.

Implements bs::shell_node_evaluable.

get_command()

const shell_node_command_expression * bs::shell_node_command::get_command ( ) const

inlinenoexcept

Get pointer to the underlying command expression.

Returns

Non-owning pointer.
