operator ossimEcefPoint()

ossimLsrPoint::operator ossimEcefPoint ( ) const

CASTING OPERATOR: Used as: myEcefVector = ossimEcefPoint(this) – looks like a constructor but is an operation on this object. ECEF knows nothing about LSR, so cannot provide an ossimEcefVector(ossimLsrPoint) constructor.

Definition at line 168 of file ossimLsrPoint.h.
