Detailed Description

This class specifies the criteria by which the TSLDataLayer query algorithm determines which entities to find.

It is an abstract class, which requires clients to provide an implementation specific to their problem domain.

◆ select() [1/2]

virtual TSLSelectorActionType TSLSelector::select ( const TSLEntity * entity )

inlinevirtual

This method should return the type of action required of the search algorithm based on the supplied entity.

NOTE : In earlier releases of MapLink, this method was const. This requirement has now been removed to allow derived classes to store data for use during the traversal of the entities.

Change in MapLink Pro 11.2. This overload was previously abstract. It is no longer abstract so that clients can choose which overload is needed. If wrap-around mode is enabled on your drawing surface, it is recommended that the overload with 2 arguments is implemented.

Parameters

entity the entity for the search

Returns: Enumerated type determines how the TSLDataLayer query algorithm proceeds as it searches for entities that match the TSLSelector object. Default implementation returns TSLSelectorActionSelectNext to select the entity.

◆ select() [2/2]

virtual TSLSelectorActionType TSLSelector::select	(	const TSLEntity *	entity,
		const TSLSelectorParams &	params )
