trait TimesOnInt

Trait providing an implicit conversion that adds a times method to Ints that will repeat a given side-effecting operation multiple times.

Here's an example in which a friendly greeting is printed three times:

3 times println("Hello again, world!")

Running the above code would yield this output:

Hello again, world!
Hello again, world!
Hello again, world!

If you need to repeat a block of statements multiple times, just enclose them in parentheses, like this:

2 times {
print("Hello ")
print("again, ")
println("world!")
}

Running the above code would yield:

Hello again, world!
Hello again, world!

This trait enables times to be invoked on 0 and any positive integer, but attempting to invoke times on a negative integer will result in an IllegalArgumentException.

class Repeater(num: Int)

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.

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 times method will be added.

Attributes

Throws
IllegalArgumentException

if num is less than zero.
