Feature Class Type: Compound Line String

A compound line string is a type of line string in which individual line strings can have different line attributes. The polyline can be drawn with distinct line types for each segment. For example, compound line strings are used for pipelines, where particular segments have special attributes to display the segments at crossing points.

The essential feature attribute data is stored in the parent feature class.

Default Attributes of the Compound Line String Feature Class (Parent Line String)
FID	Primary key
GEOM	Feature geometry polyline. For more information, see Oracle Spatial Users Guide and Reference.
LENGTH	Calculated length of all segments.
INVALID_GEOMETRY_ERROR	State of line in relation to the polyline: (TRUE = valid, Lines not connected)

Child feature class (single segments): Normally, the child line strings have few attributes, but can have one to control representation in graphics, such as "LINE_TYPE".

Default Attributes of Compound Line String Feature Class (child line string)
FID	Primary key
GEOM	Feature geometry polyline. For more information, see Oracle Spatial Users Guide and Reference.
LENGTH	Length of a single segment.
FID_PARENT	Foreign key to parent polyline.
