Core namespace of Tapestry

alive? clj

(alive? fiber)

Return whether the provided fiber is alive

asyncly clj

(asyncly f s)

(asyncly n f s)

Executes mapping function f over the provided stream s.

Returns a new stream in which items will be emitted in any order after f finishes.

Runs each item in a loom fiber.

Optionally takes a number n which will be the maximum parallelism.

fiber clj macro

(fiber & body)

Execute body on a loom fiber, returning a deferred that will resolve when the fiber completes.

fiber-loop clj macro

(fiber-loop bindings & body)

Execute a body inside a loop.

interrupt! clj

(interrupt! fiber)

Interrupt the provided fiber, causing a java.lang.InterruptedException to be thrown in the fiber

Return the provided fiberfor chaining

parallelly clj

(parallelly f s)

(parallelly n f s)

Maps f over the stream or seq s with up to n items occuring in parallel.

If n is not specified, will use unbounded parallelism (or the max parallism set via the with-max-parallelism macro).

periodically clj

(periodically period f)

(periodically period initial-delay f)

Behaves similarly to manifold.stream/periodically but relies on a loom fiber for time keeping. If no initial delay is specified runs immediately.

Also automatically coerces durations into millisecond values.

pfor clj macro

(pfor seq-exprs body-expr)

Macro which behaves identically to clojure.core.for but runs the body in parallell using fibers.

Note that bindings in :let and :when will not be evaluated in parallel.

Will force evaluation of the sequence (ie. this is no longer lazy).

send clj

(send a f & args)

A version of send that uses a loom fiber for the execution of the function f.

See clojure.core/send for details

seq->stream clj macro

(seq->stream expr)

Macro which runs an expression that returns a (presumably lazy) sequence and runs it in a fiber, returning a source stream of the results

set-stream-error-handler! clj

(set-stream-error-handler! f)

Set a function to be called when an error occurs in a tapestry returned stream.

By default will println. Set to nil to do nothing

Calls (f err msg).

timeout! clj

(timeout! fiber timeout)

(timeout! fiber timeout default)

Set the provided timeout on the provided fiber, causing a java.util.concurrent.TimeoutException to be thrown on the deferred (or default to be returrned) and the fiber to be interrupted.

Return the provied fiber for chaining.

Accepts either a number in millis or a duration.

with-max-parallelism clj macro

(with-max-parallelism n & body)

Executes the provided body with an executor that ensures that at most n fibers will run in parallel.

with-timeout clj macro

(with-timeout timeout & body)

Executes all newly spawned fibers with the provided timeout.

Accepts either a number (used as millis) or java.lang.Duration for timeout.
