Implementation details

1. - internal feature (not documented)
   bool Value  :: operator<= ( int64 i64Value )
   

   • i64Value - Big integer value

     Big integer values are 64 bit integer values.

2. - internal feature (not documented)
   bool Value  :: operator<= ( bool bValue )
   

   • bValue - Boolean value

     Valid values for Boolean values are true and false .

to list
3. Compare with date
   bool Value  :: operator<= ( odaba::Date &cDate )
   

   This implementation compares the value with the date passed in cDate . Data conversion is performed for the passed value when required. Converting date values to string values may result in different string values for the same date value depending on the national setting. Hence, string values should not be compared with date values. In this case it is more appropriate to compare the date values directly by calling toDate() .

   • cDate - Date

     The date contains day, month and year, but not the time.

4. - internal feature (not documented)
   bool Value  :: operator<= ( odaba::DateTime &cDateTime )
   

   • cDateTime - Time stamp

     A time stamp combines date and time

to list
5. Compare with double
   bool Value  :: operator<= ( double vDouble )
   

   This implementation compares the value with the double value passed in vDouble . Data conversion is performed for the passed value when required.

   • vDouble - Double value

6. Compare with integer
   bool Value  :: operator<= ( int32 iValue )
   

   This implementation compares the value with the integer value passed in iValue . Data conversion is performed for the passed value when required.

   • iValue - Integer value

     The value is passed as platform independent 32-bit integer value.

to list
7. Compare with string
   bool Value  :: operator<= ( odaba::String &sString )
   

   This implementation compares the value with the string value passed in sString . Data conversion is performed for the string when required.

   • sString - String value
to list
8. Compare with time
   bool Value  :: operator<= ( odaba::Time &cTime )
   

   This implementation compares the value with the time passed in cTime . Data conversion is performed for the passed value when required. Converting date values to string values may result in different string values for the same time value depending on the national setting. Hence, string values should not be compared with time values, directly. In this case, it is more appropriate to compare the time value directly by calling toTime() .

   • cTime - Time value

     The time value is passed in the ODABA Interface::Time format and provides time in 1/100th seconds.

to list
9. Compare with value
   bool Value  :: operator<= ( odaba::Value &cValue )
   

   This implementation compares the value with the value passed in cValue . Data conversion is performed for cValue when required.

   • cValue - Value handle

     A value handle refers to a (usually) opened value. Invalid value handles may cause an exception.
