template<typename T >

class Basic3DVector __attribute__

(

(aligned(16))

)

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 276 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.

Definition at line 283 of file oldBasic3DVector.h.

{

__attribute__::Basic3DVector

(

)

default constructor uses default constructor of T to initialize the components. For built-in floating-point types this means initialization to zero??? (force init to 0)

Definition at line 177 of file oldBasic3DVector.h.

{

__attribute__::Basic3DVector

(

const Basic3DVector &

p

)

Copy constructor from same type. Should not be needed but for gcc bug 12685.

template<class OtherPoint >

__attribute__::Basic3DVector ( const OtherPoint &  p )

explicit

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
construction from a Hep3Vector
construction from a coordinate system converter
