getCornerAzimuths

public Angle[] getCornerAzimuths()

Indicates the azimuth angles for this box's four corners, relative to geographic north. Angles are organized in the returned array as follows: begin left, begin right, end left, end right. Null elements in any index indicate that the default angle is used.

Returns:

an array of length four indicating this box's corner azimuths.

getHeightStacks

protected int getHeightStacks()

getLocations

getPillars

protected int getPillars()

getReferencePosition

public Position getReferencePosition()

Description copied from interface: Movable

A position associated with the object that indicates its aggregate geographic position. The chosen position varies among implementers of this interface. For objects defined by a list of positions, the reference position is typically the first position in the list. For symmetric objects the reference position is often the center of the object. In many cases the object's reference position may be explicitly specified by the application.

Returns:

the object's reference position, or null if no reference position is available.
