@UML(identifier="CV_DiscreteCurveCoverage",

public interface DiscreteCurveCoverage
extends DiscreteCoverage

A discrete coverage characterized by a finite spatial domain consisting of curves. Often the curves represent features such as roads, railroads, or streams. They may be elements of a network.

Example: A coverage that assigns a route a number, a name, a pavement width, and a pavement material type to each segment of a road system.

GeoAPI 2.1

Method Summary

CurveValuePair	find(DirectPosition p) Returns the nearest curve-value pair from the specified direct position.
Set<CurveValuePair>	getElements() Returns the set of curve-value pairs included in this coverage.
Set<CurveValuePair>	list() Returns the dictionary of curve-value pairs that contain the objects in the domain of the coverage each paired with its record of feature attribute values.
Set<CurveValuePair>	locate(DirectPosition p) Returns the set of curve-value pairs that include the domain objects containing the specified direct position.

Method Detail

getElements

@UML(identifier="element",
     obligation=OPTIONAL,
     specification=ISO_19123)
Set<CurveValuePair> getElements()

Returns the set of curve-value pairs included in this coverage.

Specified by:

getElements in interface DiscreteCoverage

Returns:

The set of geometry-value pairs, or null.

locate

@UML(identifier="locate",
     obligation=OPTIONAL,
     specification=ISO_19123)
Set<CurveValuePair> locate(DirectPosition p)

Returns the set of curve-value pairs that include the domain objects containing the specified direct position.

Specified by:

locate in interface DiscreteCoverage

Parameters:

p - The position where to search for geometry-value pairs.

Returns:

geometry-value pairs, or null.

list

@UML(identifier="list",
     obligation=MANDATORY,
     specification=ISO_19123)
Set<CurveValuePair> list()

Returns the dictionary of curve-value pairs that contain the objects in the domain of the coverage each paired with its record of feature attribute values.

Specified by:

list in interface Coverage

Returns:

The geometry-value pairs.

find

@UML(identifier="find",
     obligation=MANDATORY,
     specification=ISO_19123)
CurveValuePair find(DirectPosition p)

Returns the nearest curve-value pair from the specified direct position. This is a shortcut for find(p,1).

Specified by:

find in interface Coverage

Parameters:

p - The search position.

Returns:

The geometry-value pair nearest to the given position.
