Detailed Description

A Component for periodically reporting Component Port contents to a human readable text format.

The default format is a table with a header.

It can report to any data format, using the 'addMarshaller' function, which is typically done in sub classes of this component.

Configuration
The ReportingComponent is configured using its properties. For example, to enable writing a header or not. The ReportData struct describes which ports and peer components need to be monitored. You need to load properties into this struct (see RTT::Marshalling service). This struct can be filled in as such:
     <?xml version="1.0" encoding="UTF-8"?>
     <!DOCTYPE properties SYSTEM "cpf.dtd">
     <properties>
        <!-- ... other component properties .. -->

        <struct name="ReportData" type="PropertyBag">
           <!-- Monitor all ports of a Component : -->
           <simple name="Component" type="string"><description></description><value>ComponentX</value></simple>

           <!-- Monitor a single Data or base::Buffer-Port of another Component : -->
           <simple name="Port" type="string"><description></description><value>ComponentY.PortZ</value></simple>
           <!-- add as many lines as desired... -->
        </struct>
     </properties>

Member Typedef Documentation

typedef boost::tuple<std::string, RTT::base::DataSourceBase::shared_ptr, std::string,RTT::base::PropertyBase*,RTT::base::InputPortInterface*,bool,bool> DTupple [protected]

tuple that describes each sample.

Uses get<N>() to read it: @0 The qualified name of the data (componentname.portname) @1 The data source of the data. Always returns the last value. @2 A copy command to copy from this data source to another one @3 The target data source for the copy operation @4 The type of the data, "Data" (props and attrs) or "Port". @5 'newdata': The new data flag. Flags if the DataSource contains new data. @6 'tracked': True if this source may lead to additional data. If false, the source in itself will not cause to a re-scan. Used in copydata() to allow ports to be rescanned, while props and attrs never cause this (they always have newdata, but this is ignored).

Member Function Documentation

bool addMarshaller ( RTT::marsh::MarshallInterface *  headerM,
RTT::marsh::MarshallInterface *  bodyM 
)

Adds a Plugin to receive incomming data.

The marshallers become owned by this component.

Parameters:
headerA marshaller which writes out a header when this component is started. May be null (0).
bodyA marshaller wich will get periodically a serialisation request to process incomming data. May be null(0).

example: addMarshaller( new HeaderMarshaller(), new ContentsMarshaller() );

void cleanReport ( )

Implementation of base::TaskCore::configureHook().

Calls load().

void cleanupHook ( ) [virtual]

Implementation of base::TaskCore::cleanupHook().

Calls store() and clears the reporting configuration.

Definition at line 237 of file ReportingComponent.cpp.

bool configureHook ( ) [virtual]
bool copydata ( )

This real-time function makes copies of the data to be reported.

Returns:
true if new data is available.

bool screenComponent ( const std::string &  comp) [virtual]

Write state information of a component.

This method must be overridden by a subclass to be useful.

Reimplemented in FileReporting, and ConsoleReporting.
