Repeater
Class used via an implicit conversion to enable a times method to be invoked
on Ints to repeat a given side-effecting operation multiple times.
When an instance of this class is constructed, 0 and any positive number may be passed as num,
but a negative number will result in an IllegalArgumentException. If constructed with 0, the times method
on the resulting instance will return without invoking the function passed to it. If constructed with 1, the times method
will invoke the function passed to it once then return.
- Value parameters:
- num
the integer to which the
timesmethod will be added.
- Throws:
- IllegalArgumentException
if
numis less than zero.

Value members
Concrete methods
Executes the passed by-name parameter num number of times.
Executes the passed by-name parameter num number of times.
If the function completes abruptly with an exception, this method will complete abruptly with the same
exception immediately. Thus in the case of an exception, this method may actually invoke the
passed function fewer than num times.
- Value parameters:
- fun
the by-name parameter to execute
numtimes
