T __attribute__::barePhi

const

Azimuthal angle. The value is returned in radians, in the range (-pi,pi]. Same precision as the system atan2(x,y) function. The return type is Geom::Phi<T>, see it's documentation.

Definition at line 260 of file oldBasic3DVector.h.

T __attribute__::bareTheta

const

Polar angle. The value is returned in radians, in the range [0,pi] Same precision as the system atan2(x,y) function. The return type is Geom::Phi<T>, see it's documentation.

Explicit constructor from other (possibly unrelated) vector classes The only constraint on the argument type is that it has methods x(), y() and z(), and that these methods return a type convertible to T. Examples of use are
construction from a Basic3DVector with different precision
