◆ get_child()

Logger rclcpp::Logger::get_child ( const std::string & suffix )

Return a logger that is a descendant of this logger.

The child logger's full name will include any hierarchy conventions that indicate it is a descendant of this logger. For example, get_logger('abc').get_child('def') will return a logger with name abc.def.

Parameters

[in] suffix the child logger's suffix

Returns: a logger with the fully-qualified name including the suffix, or; a dummy logger if this logger is invalid (e.g. because logging is disabled).

◆ get_effective_level()

Logger::Level rclcpp::Logger::get_effective_level ( ) const

Get effective level for current logger.

The effective level is determined as the severity level of the logger if it is set, otherwise it is the first specified severity level of the logger's ancestors, starting with its closest ancestor. The ancestor hierarchy is signified by logger names being separated by dots: a logger named x is an ancestor of x.y, and both x and x.y are ancestors of x.y.z, etc. If the level has not been set for the logger nor any of its ancestors, the default level is used.

Exceptions

rclcpp::exceptions::RCLError if any error happens.
