OperatorBoundary

public OperatorBoundary()

Method Details

getType

public Operator.Type getType()

Specified by:

getType in class Operator

execute

public abstract GeometryCursor execute(GeometryCursor geoms,
 ProgressTracker progress_tracker)

Calculates the boundary geometry.

Parameters:

geoms - The input geometry cursor.

progress_tracker - The progress tracker, that allows to cancel the lengthy operation.

Returns:

Returns a cursor over boundaries for each geometry.

execute

public abstract Geometry execute(Geometry geom,
 ProgressTracker progress_tracker)

Calculates the boundary.

Parameters:

geom - The input geometry.

progress_tracker - The progress tracker, that allows to cancel the lengthy operation.

Returns:

Returns the boundary. For Point - returns an empty point. For Multi_point - returns an empty point. For Envelope - returns a polyline, that bounds the envelope. For Polyline - returns a multipoint, using OGC specification (includes path endpoints, using mod 2 rule). For Polygon - returns a polyline that bounds the polygon (adds all rings of the polygon to a polyline).
