Member Function Documentation

isCoaligned()

EForwardBackward isCoaligned

(

const CDCTrajectory2D &

trajectory2D

)

const

Checks if the last entity in the vector lies greater or lower travel distance than the last entity.

Returns:

• EForwardBackward::c_Forward if the last entity lies behind the first.
• EForwardBackward::c_Backward if the last entity lies before the first.
