RangeIterator helper functions allow to use RangeItartor in easier usage in loop statements.
- Example
-
RangeIterator Qore::xrange |
( |
int |
start, |
|
|
int |
stop, |
|
|
int |
step = 1 , |
|
|
any |
val |
|
) |
| |
Returns a RangeIterator containing an arithmetic progression of integers.
- Code Flags:
- RET_VALUE_ONLY
- Example:
- Parameters
-
start | the initial value |
stop | the final value |
step | the step; the default is 1; must be greater than 0; the function throws a RANGE-ERROR exception when this argument is < 1 |
val | an optional value to be returned instead of the default integer value |
- Return values
-
Returns | a RangeIterator containing an arithmetic progression of integers. |
- Exceptions
-
RANGEITERATOR-ERROR | this exception is thrown if step < 1 |
- See Also
- range
- Note
- the main difference between range() and xrange() is that range returns a real list and xrange() returns a RangeIterator

- Qore 0.8.6

Qore 0.8.11.1 this function takes the optional val argument
RangeIterator Qore::xrange |
( |
int |
stop, |
|
|
any |
val |
|
) |
| |
Returns a RangeIterator containing an arithmetic progression of integers with start = 0 and step = 1.
This is an overloaded version of xrange(int, int, int) meaning xrange
(0, stop
, 1)
- Code Flags:
- CONSTANT
- Example:
- Parameters
-
stop | the final value |
val | an optional value to be returned instead of the default integer value |
- Return values
-
Returns | a RangeIterator containing an arithmetic progression of integers with start = 0 and step = 1. |
