Function Documentation

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 274 of file extBasic3DVector.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 281 of file extBasic3DVector.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)

__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
