Detailed Description

GenericAnalyzerBase is the base class for GenericAnalyzer and OtherAnalyzer.

GenericAnalyzerBase contains the getPath(), getName(), analyze() and report() functions of the Generic and Other Analyzers. It is a virtual class, and cannot be instantiated or loaded as a plugin. Subclasses are responsible for implementing the init() and match() functions.

The GenericAnalyzerBase holds the state of the analyzer, and tracks if items are stale, and if the user has the correct number of items.

virtual bool diagnostic_aggregator::GenericAnalyzerBase::analyze ( const boost::shared_ptr< StatusItem > item ) [inline, virtual]

bool diagnostic_aggregator::GenericAnalyzerBase::init	(	const std::string	base_path,
		const ros::NodeHandle &	n
	)		`[pure virtual]`

Analyzer is initialized with base path and namespace.

The Analyzer initialized with parameters in its given namespace. The "base_path" is common to all analyzers, and needs to be prepended to all DiagnosticStatus names.

Parameters:

base_path	: Common to all analyzers, prepended to all processed names. Starts with "/".
n	: NodeHandle with proper private namespace for analyzer.

Implements diagnostic_aggregator::Analyzer.

Implemented in diagnostic_aggregator::GenericAnalyzer, and diagnostic_aggregator::OtherAnalyzer.

bool diagnostic_aggregator::GenericAnalyzerBase::init	(	const std::string	path,
		const std::string	nice_name,
		double	timeout = `-1.0`,
		int	num_items_expected = `-1`,
		bool	discard_stale = `false`
