Detailed Description

an abstract iterator class used to print out property values

The main purpose of implementations of this class is to provide (via its write(std::ostream*) function) the means for printing the values. The other functions support iteration.

Member Function Documentation

virtual bool lsst::pex::logging::PrinterIter::notAtEnd ( ) const

pure virtual

return true if this iterator is not pointing just past the last value in the list.

Implemented in lsst::pex::logging::WrappedPrinterIter, lsst::pex::logging::BaseTmplPrinterIter< T >, lsst::pex::logging::BaseTmplPrinterIter< lsst::daf::base::DateTime >, and lsst::pex::logging::BaseTmplPrinterIter< bool >.

virtual bool lsst::pex::logging::PrinterIter::notLTBegin ( ) const

pure virtual

return true if this iterator is not pointing before the first value in the list. Thus, *this should return a legal string.

Implemented in lsst::pex::logging::WrappedPrinterIter, lsst::pex::logging::BaseTmplPrinterIter< T >, lsst::pex::logging::BaseTmplPrinterIter< lsst::daf::base::DateTime >, and lsst::pex::logging::BaseTmplPrinterIter< bool >.

virtual bool lsst::pex::logging::PrinterIter::operator!= ( const PrinterIter &  that ) const

pure virtual

return true if this iterator is not pointing to the same value as another pointer. This method is not recommend for testing whether an iterator is past the beginning or end of the list; notAtEnd() and notLTBegin() are more efficient.

Implemented in lsst::pex::logging::WrappedPrinterIter, lsst::pex::logging::BaseTmplPrinterIter< T >, lsst::pex::logging::BaseTmplPrinterIter< lsst::daf::base::DateTime >, and lsst::pex::logging::BaseTmplPrinterIter< bool >.

const std::string lsst::pex::logging::PrinterIter::operator* ( ) const

inline

return a string version of the property value. This simply uses write(std::ostream*) to write to a string; consequently using write(std::ostream*) is more efficient for most purposes.

Definition at line 108 of file PropertyPrinter.h.

                                      {
        std::ostringstream out;
        write(&out);
        return out.str();
    }

virtual PrinterIter& lsst::pex::logging::PrinterIter::operator++ ( )

pure virtual

move the iterator forward one position

Implemented in lsst::pex::logging::WrappedPrinterIter, lsst::pex::logging::BaseTmplPrinterIter< T >, lsst::pex::logging::BaseTmplPrinterIter< lsst::daf::base::DateTime >, and lsst::pex::logging::BaseTmplPrinterIter< bool >.

virtual PrinterIter& lsst::pex::logging::PrinterIter::operator-- ( )

pure virtual

move the iterator backward one position

Implemented in lsst::pex::logging::WrappedPrinterIter, lsst::pex::logging::BaseTmplPrinterIter< T >, lsst::pex::logging::BaseTmplPrinterIter< lsst::daf::base::DateTime >, and lsst::pex::logging::BaseTmplPrinterIter< bool >.

virtual bool lsst::pex::logging::PrinterIter::operator== ( const PrinterIter &  that ) const

pure virtual

return true if this iterator is pointing to the same value as another pointer. This method is not recommend for testing whether an iterator is past the beginning or end of the list; notAtEnd() and notLTBegin() are more efficient.

Implemented in lsst::pex::logging::WrappedPrinterIter, lsst::pex::logging::BaseTmplPrinterIter< T >, lsst::pex::logging::BaseTmplPrinterIter< lsst::daf::base::DateTime >, and lsst::pex::logging::BaseTmplPrinterIter< bool >.

virtual std::ostream& lsst::pex::logging::PrinterIter::write ( std::ostream *  strm ) const

pure virtual

write the value pointed to by this iterator to the given stream

Implemented in lsst::pex::logging::BoolPrinterIter, lsst::pex::logging::DateTimePrinterIter, lsst::pex::logging::WrappedPrinterIter, and lsst::pex::logging::TmplPrinterIter< T >.
