	Static operation that combines two filters using the specified binary logical operation.
	Filter (System::IntPtr unmanaged, System::Boolean autoDelete)
	Constructs a Filter object based on an unmanaged instance of the object.
System::Void	Process (OSGeo::FDO::Filter::IFilterProcessor *processor)
	Abstract operation that takes an IFilterProcessor as an argument. Concrete filter subclasses must override this method and pass themselves as an argument to the appropriate filter processor operation.
System::String *	ToString ()
	Converts the filter expression to its well defined text representation.
