lsst::pex::policy::PolicyParserFactory Class Reference

an abstract factory class for creating PolicyParser instances. This class is used by the PolicySource class to determine the format of a stream of serialized Policy data and then parse it into a Policy instance. It is intended that for supported each format there is an implementation of this class and a corresponding PolicyParser class. More...

Detailed Description

an abstract factory class for creating PolicyParser instances. This class is used by the PolicySource class to determine the format of a stream of serialized Policy data and then parse it into a Policy instance. It is intended that for supported each format there is an implementation of this class and a corresponding PolicyParser class.

Member Function Documentation

virtual PolicyParser* lsst::pex::policy::PolicyParserFactory::createParser ( Policy &  policy, bool  strict = true  ) const

pure virtual

create a new PolicyParser class and return a pointer to it. The caller is responsible for destroying the pointer.

Parameters

policy	the Policy object that data should be loaded into.
strict	if true, be strict in reporting errors in file contents and syntax. If false, errors will be ignored if possible; often, such errors will result in some data not getting loaded. The default is true.

Implemented in lsst::pex::policy::paf::PAFParserFactory.

const std::string & lsst::pex::policy::PolicyParserFactory::getFormatName ( )

virtual

return the name for the format supported by the parser

Reimplemented in lsst::pex::policy::paf::PAFParserFactory.

                                                    { 
    return UNRECOGNIZED; 
}

virtual bool lsst::pex::policy::PolicyParserFactory::isRecognized ( const std::string &  leaders ) const

pure virtual

analyze the given string assuming contains the leading characters from the data stream and return true if it is recognized as being in the format supported by this parser. If it is, return the name of the this format;

Implemented in lsst::pex::policy::paf::PAFParserFactory.
