Delaying one-shot signal objects
View Patent ↗A device may include a processor to execute a thread. The processor may be further configured to execute a set of wrappers that are called from within the thread to invoke a set of one-shot signal objects to generate delayed signals. Each of the set of wrappers may be configured to detect whether different ones of one-shot signal objects that were invoked from within the thread have generated signals at periodic time intervals, determine a delay to be used for invoking one of the set of one-shot signal objects, and invoke the one of the set of one-shot signal object to generate one of the delayed signals based on the delay when the different ones of one-shot signal objects have generated signals at periodic time intervals. The processor may be further configured to receive the delayed signals generated from the set of one-shot signal objects over a time period.
