◆ EvaluateExpression()

bool CommandObjectExpression::EvaluateExpression	(	llvm::StringRef	expr,
		Stream &	output_stream,
		Stream &	error_stream,
		CommandReturnObject &	result
	)

protected

Evaluates the given expression.

Parameters

output_stream	The stream to which the evaluation result will be printed.
error_stream	Contains error messages that should be displayed to the user in case the evaluation fails.
result	A CommandReturnObject which status will be set to the appropriate value depending on evaluation success and whether the expression produced any result.

Returns: Returns true iff the expression was successfully evaluated, executed and the result could be printed to the output stream.

◆ HandleCompletion()

void CommandObjectExpression::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.

Definition at line 309 of file CommandObjectExpression.cpp.

◆ IOHandlerInputComplete()

void CommandObjectExpression::IOHandlerInputComplete	(	IOHandler &	io_handler,
		std::string &	data
	)

overrideprotectedvirtual

Called when a line or lines have been retrieved.

This function can handle the current line and possibly call IOHandler::SetIsDone(true) when the IO handler is done like when "quit" is entered as a command, of when an empty line is received. It is up to the delegate to determine when a line should cause a IOHandler to exit.

Implements lldb_private::IOHandlerDelegate.

Definition at line 478 of file CommandObjectExpression.cpp.

◆ IOHandlerIsInputComplete()

bool CommandObjectExpression::IOHandlerIsInputComplete	(	IOHandler &	io_handler,
		StringList &	lines
	)

overrideprotectedvirtual

Called to determine whether typing enter after the last line in lines should end input.

This function will not be called on IOHandler objects that are getting single lines.

Parameters

[in]	io_handler	The IOHandler that responsible for updating the lines.
[in]	lines	The current multi-line content. May be altered to provide alternative input when complete.

Returns: Return an boolean to indicate whether input is complete, true indicates that no additional input is necessary, while false indicates that more input is required.

Reimplemented from lldb_private::IOHandlerDelegate.
