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.

Update state with new StatusItem.

Implements diagnostic_aggregator::Analyzer.

Definition at line 110 of file generic_analyzer_base.h.

virtual std::string diagnostic_aggregator::GenericAnalyzerBase::getName ( ) const

virtual std::string diagnostic_aggregator::GenericAnalyzerBase::getPath ( ) const

inlinevirtual

Returns full prefix (ex: "/Robot/Power System")

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  )

Definition at line 85 of file generic_analyzer_base.h.

virtual bool diagnostic_aggregator::GenericAnalyzerBase::match ( const std::string  name )

pure virtual

Match function isn't implemented by GenericAnalyzerBase.

Implements diagnostic_aggregator::Analyzer.

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

virtual std::vector<boost::shared_ptr<diagnostic_msgs::DiagnosticStatus> > diagnostic_aggregator::GenericAnalyzerBase::report ( )

inlinevirtual

Reports current state, returns vector of formatted status messages.

Returns

Vector of DiagnosticStatus messages. They must have the correct prefix for all names.

Implements diagnostic_aggregator::Analyzer.

Reimplemented in diagnostic_aggregator::GenericAnalyzer, diagnostic_aggregator::OtherAnalyzer, and diagnostic_aggregator::DiscardAnalyzer.
