Detailed Description

Represents a command expression composed of expandable children.

The node holds ownership of a vector of expandable child nodes and expands by expanding each child in sequence.

Constructor & Destructor Documentation

shell_node_command_expression()

bs::shell_node_command_expression::shell_node_command_expression ( std::vector< std::unique_ptr< shell_node_expandable > > &&  vChildren )

explicit

Construct a command expression node.

Exceptions

shell_node_invalid_argument	If vChildren is empty.
shell_node_invalid_argument	If first vChildren is null pointer.
shell_node_invalid_argument	If all vChildren are null pointers.

Parameters

vChildren

Vector of child expandable nodes (moved in).

Member Function Documentation

expand()

void bs::shell_node_command_expression::expand ( std::vector< std::string > &  vTokens, shell_session &  oSession, bool  bSplit  ) const

overridevirtual

Expand the expression by expanding its children in order. Expand the node into textual tokens.

Parameters

vTokens	Vector where generated token strings will be appended.
oSession	Session context (used for variable/argument lookup, etc.).
bSplit	When true apply word-splitting semantics; otherwise keep as single token.

.

Implements bs::shell_node_expandable.

get_children()

const std::vector< std::unique_ptr< shell_node_expandable > > & bs::shell_node_command_expression::get_children ( ) const

inlinenoexcept

Access the child nodes.

Returns

const reference to the internal children vector.
