◆ ~CommandObjectExpression()

CommandObjectExpression::~CommandObjectExpression ( )

Member Function Documentation

◆ DoExecute()

bool CommandObjectExpression::DoExecute ( llvm::StringRef  command,
CommandReturnObject result 

◆ EvaluateExpression()

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

Evaluates the given expression.

output_streamThe stream to which the evaluation result will be printed.
error_streamContains error messages that should be displayed to the user in case the evaluation fails.
resultA CommandReturnObject which status will be set to the appropriate value depending on evaluation success and whether the expression produced any result.
Returns true iff the expression was successfully evaluated, executed and the result could be printed to the output stream.

Definition at line 359 of file CommandObjectExpression.cpp.

◆ GetEvalOptions()

EvaluateExpressionOptions CommandObjectExpression::GetEvalOptions ( const Target target)

Return the appropriate expression options used for evaluating the expression in the given target.

Definition at line 319 of file CommandObjectExpression.cpp.

◆ GetMultilineExpression()

void CommandObjectExpression::GetMultilineExpression ( )

Definition at line 476 of file CommandObjectExpression.cpp.

◆ GetOptions()

Options * CommandObjectExpression::GetOptions ( )

Reimplemented from lldb_private::CommandObject.

Definition at line 247 of file CommandObjectExpression.cpp.

◆ HandleCompletion()

void CommandObjectExpression::HandleCompletion ( CompletionRequest request)

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.

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

Reimplemented from lldb_private::CommandObject.

Definition at line 249 of file CommandObjectExpression.cpp.

◆ IOHandlerInputComplete()

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

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 448 of file CommandObjectExpression.cpp.

References lldb_private::Stream::EOL(), lldb_private::Stream::PutCString(), and lldb_private::Stream::Write().

◆ IOHandlerIsInputComplete()

bool CommandObjectExpression::IOHandlerIsInputComplete ( IOHandler io_handler,
StringList lines 

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.

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