◆ HandleArgumentCompletion()

void CommandAlias::HandleArgumentCompletion	(	CompletionRequest &	request,
		OptionElementVector &	opt_element_vector
	)

overridevirtual

The default version handles argument definitions that have only one argument type, and use one of the argument types that have an entry in the CommonCompletions.

Override this if you have a more complex argument setup. FIXME: we should be able to extend this to more complex argument definitions provided we have completers for all the argument types.

The input array contains a parsed version of the line.

We've constructed the map of options and their arguments as well if that is helpful for the completion.

Parameters

[in,out] request The completion request that needs to be answered.

Reimplemented from lldb_private::CommandObject.

Definition at line 125 of file CommandAlias.cpp.

References IsValid(), and m_underlying_command_sp.

◆ HandleCompletion()

void CommandAlias::HandleCompletion ( CompletionRequest & request )

overridevirtual

This default version handles calling option argument completions and then calls HandleArgumentCompletion if the cursor is on an argument, not an option.

Don't override this method, override HandleArgumentCompletion instead unless you have special reasons.

Parameters

[in,out] request The completion request that needs to be answered.

Reimplemented from lldb_private::CommandObject.
