Detailed Description

The simple class for rules.

By now we have only connect rules, so the one class is enough. Maybe in future the set of classes for different rule types will be needed.

Member Function Documentation

virtual bool GNMRule::CanConnect	(	const CPLString &	soSrcLayerName,
		const CPLString &	soTgtLayerName,
		const CPLString &	soConnLayerName = `""`
	)

virtual

Check if connection can take place.

Parameters

Returns: true if can connect features from soSrcLayerName and soTgtLayerName via soConnLayerName

virtual GNMRuleType GNMRule::GetType ( ) const

virtual

This is for future use to indicate the rule type/ Now return only GRTConnection type.

virtual bool GNMRule::IsAcceptAny ( ) const

virtual

Indicator of any layer state.

virtual bool GNMRule::IsValid ( ) const

virtual

This function indicate if rule string was parsed successfully.
