Details
setFormatter(OutputFormatterInterface $formatter)
Sets output formatter.
Parameters
| OutputFormatterInterface | $formatter |
OutputFormatterInterface getFormatter()
Returns current output formatter instance.
Return Value
| OutputFormatterInterface |
setDecorated(bool $decorated)
Sets the decorated flag.
Parameters
| bool | $decorated | Whether to decorate the messages |
bool isDecorated()
Gets the decorated flag.
Return Value
| bool | true if the output will decorate messages, false otherwise |
setVerbosity(int $level)
Sets the verbosity of the output.
Parameters
| int | $level | The level of verbosity (one of the VERBOSITY constants) |
int getVerbosity()
Gets the current verbosity of the output.
Return Value
| int | The current level of verbosity (one of the VERBOSITY constants) |
bool isQuiet()
Returns whether verbosity is quiet (-q).
Return Value
| bool | true if verbosity is set to VERBOSITY_QUIET, false otherwise |
bool isVerbose()
Returns whether verbosity is verbose (-v).
Return Value
| bool | true if verbosity is set to VERBOSITY_VERBOSE, false otherwise |
bool isVeryVerbose()
Returns whether verbosity is very verbose (-vv).
Return Value
| bool | true if verbosity is set to VERBOSITYVERYVERBOSE, false otherwise |
bool isDebug()
Returns whether verbosity is debug (-vvv).
Return Value
| bool | true if verbosity is set to VERBOSITY_DEBUG, false otherwise |
writeln(string|array $messages, int $options = self::OUTPUT_NORMAL)
Writes a message to the output and adds a newline at the end.
Parameters
| string|array | $messages | The message as an array of lines of a single string |
| int | $options | A bitmask of options (one of the OUTPUT or VERBOSITY constants), 0 is considered the same as self::OUTPUTNORMAL | self::VERBOSITYNORMAL |
write(string|array $messages, bool $newline = false, int $options = self::OUTPUT_NORMAL)
Writes a message to the output.
Parameters
| string|array | $messages | The message as an array of lines or a single string |
| bool | $newline | Whether to add a newline |
| int | $options | A bitmask of options (one of the OUTPUT or VERBOSITY constants), 0 is considered the same as self::OUTPUTNORMAL | self::VERBOSITYNORMAL |
