rotation angle

buildStaticRotation

public static RotationAngle buildStaticRotation(double angle)

Always returns the fixed angle.

Parameters:

angle - angle

Returns:

rotation angle

buildStaticRotation

public static RotationAngle buildStaticRotation(java.lang.String string)

Parses the rotation angle from the specified string.

Parameters:

string - angle as string
