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.

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

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 >.
