Member Function Documentation

◆ operator!=()

bool CartoType::TViewState::operator!= ( const TViewState aOther) const

The inequality operator.

◆ operator<()

bool CartoType::TViewState::operator< ( const TViewState aOther) const

The less-than operator.

◆ operator==()

bool CartoType::TViewState::operator== ( const TViewState aOther) const

The equality operator.

◆ ReadFromXml()

TResult CartoType::TViewState::ReadFromXml ( const char *  aXmlText)

Reads a view state object from its XML form.

◆ ToXml()

std::string CartoType::TViewState::ToXml ( ) const
