Detailed Description

Base interface for nodes that expand to tokens (strings).

Expandable nodes append one or more strings into the vTokens vector. The bSplit flag indicates whether word-splitting rules should be applied.

Constructor & Destructor Documentation

shell_node_expandable()

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

inline

Construct an expandable node.

Parameters

nType	Node type.
nPos	Node position.

Member Function Documentation

expand()

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

pure virtual

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.

Implemented in bs::shell_node_command_expression, bs::shell_node_str, bs::shell_node_str_back, bs::shell_node_word, bs::shell_node_unicode, bs::shell_node_session_extractor, and bs::shell_node_dollar_command.
