    This is the documentation for the ThreadCSO Library. Notable packages include:

    Definition Classes
    root
  • package threadcso

    The standard threadCSO API.

    The standard threadCSO API. Most modules using CSO will need only the declaration:

    import io.threadcso._

    The present version of the ThreadCSO library API is 1.2Rr (for some number r)

    The revision number (Rr) will change if bugs are corrected but the code remains consistent with the previous API. Its minor version number will change if there is a correction to the code that breaks consistency with the previous API. Its major version will change if there is a substantial change in the semantics of an important CSO construct.

    August 2017: changes 1.1 => 1.2

    • renaming of very many internal classes and packages
    • basic channel implementations are more efficient, in some case much more so
    • alternation reliability improved
    • debugger registration of alternations is no longer needed
    • home-grown semaphores can specify which component they are part of: this makes interpreting a stack backtrace very much easier
    • there is a flexible logging system that is compatible with the debugger

    April 2016: changes 1.0 => 1.1

    • Extended rendezvous read operator is now ?? (was ?)
    • Extended rendezvous read event notation is now =??=> (was =?=>>)
    • The notation inport ? f is now equivalent to f(inport?()) This makes for a tidier layout when the function f is an explicit functional expression.

    Feb 1 2017: changes 1.1R1 => 1.1R2

    • Removed dependencies on deprecated Java->Scala functions: replaced with .asJava

    This package implements the syntax of the CSO alternation notations, and provides hooks for the semantics of that notation.

    This package implements the syntax of the CSO alternation notations, and provides hooks for the semantics of that notation.

    The body of an alternation specification consists of a sequence (possibly empty) of executable event specifications separated by | and possibly followed by:

    | after(timeout) ==> { ... }

    or

    | orelse ==> { ... }

    or

    | after(timeout) ==> { ... } |  orelse ==> { ... }

    An executable event specification takes one of the following forms:

    outport              =!=>  OutEvent
    (guard && outport)   =!=>  OutEvent
    inport               =?=>  InEvent
    (guard && inport)    =?=>  InEvent
    inport               =??=> InEvent     // extended rendezvous form
    (guard && inport)    =??=> InEvent     // extended rendezvous form

    Concessions to readability: a Chan expression may appear in place of a port expression.

    Events and their effects

    OutEvent form:                        Effect when triggered
    {expr}                                outport!expr
    {expr} ==> { command: Unit }          {outport!expr; command}
    InEvent form:                         Effect when triggered
    { bv => body: Unit }                  {val bv=inport?(); body }

    For an extended rendezvous InEvent the correspondence is

    { bv => body: Unit }                  { inport??({ bv => body}) }
