public interface Invocable

A task (typically either a Runnable or Invocable.Callable that declares how it will behave when invoked:

  • blocking, the invocation will certainly block (e.g. performs blocking I/O)
  • non-blocking, the invocation will certainly not block
  • either, the invocation may block

Static methods and are provided that allow the current thread to be tagged with a ThreadLocal to indicate if it has a blocking invocation type.
