Member Function Documentation

_VDBL_dateinterval _VDBL_dateinterval::operator * (  double    d )  const
 

Date differences can be multiplied by or divided through doubles. E.g., half the time between two dates would be (d1-d2)/2.

_VDBL_dateinterval& _VDBL_dateinterval::operator *= (  double    d ) 
 

Date differences can be multiplied by or divided through doubles. E.g., half the time between two dates would be (d1-d2)/2.

_VDBL_date _VDBL_dateinterval::operator+ (  const _VDBL_date &    _d )  const
 

Add a date difference to a date

_VDBL_dateinterval& _VDBL_dateinterval::operator+ (  const _VDBL_dateinterval &    _v )  const
 

Date differences can be added/subtracted using this operator

_VDBL_dateinterval& _VDBL_dateinterval::operator+= (  const _VDBL_dateinterval &    _v ) 
 

Date differences can be added/subtracted using this operator

_VDBL_dateinterval& _VDBL_dateinterval::operator- (  const _VDBL_dateinterval &    _v )  const
 

Date differences can be added/subtracted using this operator

_VDBL_dateinterval& _VDBL_dateinterval::operator-= (  const _VDBL_dateinterval &    _v ) 
 

Date differences can be added/subtracted using this operator

_VDBL_dateinterval _VDBL_dateinterval::operator/ (  double    d )  const
 

Date differences can be multiplied by or divided through doubles. E.g., half the time between two dates would be (d1-d2)/2.

_VDBL_dateinterval& _VDBL_dateinterval::operator/= (  double    d ) 
 

Date differences can be multiplied by or divided through doubles. E.g., half the time between two dates would be (d1-d2)/2.
