TypeOfList Property

Description

A bit mask showing the types of McFeatures objects the list can contain.

Property type

A mcFeaturesType enumeration.

Syntax

object.TypeOfList [= value]

The TypeOfList Property syntax has these parts:

Part	Description
object	An expression evaluating to an object of type McFeaturesList.
value	A mcFeaturesType enumeration, as described in settings.

Settings

The settings for value are:

Constant		Value	Description
	mcftEmptyAny	0	Type is in an unknown state. For the McFeaturesList.TypeOfList property, any McFeatures type may be in the list
	mcftHasCoordsAny	1	This bit indicates that the feature has boundary, line or point coordinates
	mcftEllipseAny	2	This bit indicates that an McRegions feature is an ellipse
	mcftRectangleAny	4	This bit indicates that an McRegions feature is a rectangle
	mcftMultipleAny	256	This bit indicates that an McFeatures object has multiple features
	mcftRotatableAny	16	Not Implemented Yet. This bit indicates that a feature may be rotated
	mcftSquareAny	32	Not Implemented Yet. This bit indicates that a feature is constrained to a square bounding box
	mcftScanListAny	1024	This bit indicates that a feature has a scan list representation
	mcftEmptyRegions	4096	This bit indicates that the McFeature is an McRegions. For the McFeaturesList.TypeOfList property, only McRegions may be in the list
	mcftOutlineScanList	5120	A scan list created from a closed polygon outline
	mcftOutline	4097	A McRegions feature described by a closed polygon outline
	mcftBox	4100	A rectangular McRegions feature
	mcftFreeBox	4117	Not Implemented Yet. A rectangular McRegions feature that may be rotated to some angle.
	mcftSquare	4132	Not Implemented Yet. A square McRegions feature
	mcftFreeSquare	4149	Not Implemented Yet. A square McRegions feature that may be rotated to some angle.
	mcftEllipse	4099	An elliptical McRegions feature
	mcftCircle	4131	Not Implemented Yet. An circular McRegions feature
	mcftFreeEllipse	4115	Not Implemented Yet. An elliptical McRegions feature that may be rotated to some angle.
	mcftScanList	5120	The McRegions has a scan list representation
	mcftMultipleRegions	4352	Returned from McRegions.Type(-1) if there are multiple features (sub-regions)
	mcftEmptyLines	8192	This bit indicates that the McFeature is an McLines. For the McFeaturesList.TypeOfList property, only McLines may be in the list
	mcftPolyline	8193	The McLines feature may be a polyline (has more than one line segment).
	mcftLine	8197	The McLines feature is a single line segment
	mcftMultipleLines	8448	Returned from McLines.Type(-1) if there are multiple features (sub-regions)
	mcftEmptyPoints	16384	This bit indicates that the McFeature is an McPoints. For the McFeaturesList.TypeOfList property, only McPoints may be in the list
	mcftPointScanList	17408	A scan list marked by a set of points
	mcftPoint	16385	A McPoints feature
	mcftMultiplePoints	16640	Returned from McPoints.Type(-1) if there are multiple features (sub-regions)
	mcftMaskFeatureType	28672	mask for mcftEmptyRegions, mcftEmptyLines or mcftEmptyPoints
	mcftMaskTypeDetail	4095	mask for type details

Remarks

The McFeaturesList collection can contain instances of any of the classes derived from McFeatures (McRegions, McLines or McPoints). By default, the list may contain instances of objects of any of these types. But this property may be assigned any mix of the three mcFeaturesType flags OR'ed together, mcftEmptyRegions, mcftEmptyLines and mcftEmptyPoints. If assigned mcftEmptyAny, then all three are assumed to be acceptable types and mcftMaskFeatureType (which is the three type flags OR'ed together) is how the property is exposed.

This property may be changed only when the list is empty (i.e., when the Count property is zero).

Exceptions

Assignment with non-zero Count is illegal, as is assignment with any bit values other than mcftEmptyRegions, mcftEmptyLines and mcftEmptyPoints.
