Constructor Detail

TLcdEllipsoidalShapePointEnumerationFactory

public TLcdEllipsoidalShapePointEnumerationFactory()

Constructor for the TLcdEllipsoidalShapePointEnumerationFactory object. Uses a default ILcdEllipsoid object, i.e., TLcdEllipsoid.

TLcdEllipsoidalShapePointEnumerationFactory

public TLcdEllipsoidalShapePointEnumerationFactory(ILcdEllipsoid aEllipsoid)

Constructor for the TLcdEllipsoidalShapePointEnumerationFactory object.

Parameters:

aEllipsoid - ellipsoid representing the earth to be used.

Method Detail

setUseGeneralShapeEnumeration

public void setUseGeneralShapeEnumeration(boolean aUseGeneralShapeEnumeration)

Sets the useGeneralShapeEnumeration attribute of the TLcdEllipsoidalShapePointEnumerationFactory object.

Parameters:

aUseGeneralShapeEnumeration - The new useGeneralShapeEnumeration value.

isUseGeneralShapeEnumeration

public boolean isUseGeneralShapeEnumeration()

Gets the useGeneralShapeEnumeration attribute of the TLcdEllipsoidalShapePointEnumerationFactory object.

Returns:

The useGeneralShapeEnumeration value.

createPointEnumeration

public java.util.Enumeration createPointEnumeration(ILcdShape aShape,
                                                    double aStepSize)
                                             throws java.lang.IllegalArgumentException

Returns an enumeration of ILcdPoint objects contained by the ILcdShape. Knows to generate an enumeration for the following types of objects:

• ILcdPolyline
• ILcdPolygon
• ILcdPolypoint
• ILcdBounds
• TLcdLonLatBuffer

If the property isUseGeneralShapeEnumeration() returns true ILcdShape objects in general can be enumerated. This general method may be quite expensive though.

Parameters:

aStepSize - the step size, expressed in meters, to be used for the discretization of the ILcdShape

aShape - Description of Parameter

Returns:

Description of the Returned Value

Throws:

java.lang.IllegalArgumentException - is thrown if the property isUseGeneralShapeEnumeration() returns false and no implementation is available.
