Join-pattern
Join-patterns provides a way to write concurrent, parallel and distributed computer programs by message passing. Compared to the use of threads and locks, this is a high level programming model using communication constructs model to abstract the complexity of concurrent environment and to allow scalability. Its focus is on the execution of a chord between messages atomically consumed from a group of channels.This template is based on join-calculus and use pattern matching. Concretely, this is done by allowing the join definition of several functions and/or channels by matching concurrent call and messages patterns. It employs the behavioral and the concurrency pattern because it makes easier and more flexible for these entities to communicate and deal with the multi-threaded programming paradigm.
