Instance Method Details

#repeat_n_seconds(n = 1, &block) ⇒ Object

Repeats a block until the time is up. Returns the number of passes. All Exceptions are caught (=> bad blocks seem to run faster). Example (using Numeric):

3.seconds do
 puts Time.now.inspect
end

Example (using KKernel):

repeat_n_seconds 3 do
 puts Time.now.inspect
end
