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 293 of file oldBasic3DVector.h.

299 {
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 300 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)

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 coordinate system converter
