Functional Reactive Lib with Core Java

This is a nano lib, based on a few classes that will give you a handful of functional elements that you can use in your core Java project. If you want to know more about it, have a look at my Youtube Series about this topic.

JDK8 or JDK9 and above

I compiled this with the Open JDK8. Previous versions at maven central are build ith JDK10. I went away from the JDK10, because most projects I know, are using JDK8 in production right know. But, if you want to use this with JDK9/10/11/... you can use it.. it is working perfect! Only if you start using the JMS, it could be helpful to add a module-info.java Add the following lines, switch inside the pom.xml to the JDK version you prefer, start a mvn clean install and be happy ;-)

module rapidpm.functional.reactive {
 exports org.rapidpm.frp;
 exports com.svenruppert.functional.functions;
 exports com.svenruppert.functional.matcher;
 exports com.svenruppert.functional.memoizer;
 exports com.svenruppert.functional.model;
 exports com.svenruppert.functional.model.serial;
 exports com.svenruppert.functional.reactive;
}

02.00.00-SRU

Changing to new namespace. The package will be under com.svenruppert:functional-reactive now

01.01.00-RPM-SNAPSHOT

This release we will increase test coverage and documentation. The basic structures and functions are in production used since longer time. Adding Apache Lic header to all files

01.00.07-RPM

• Transformations
  • static Function<Iterator, Stream> iteratorToStream()
• <V, R> Result thenCombineFlat(V value, BiFunction<T, V, R> func)
• started Youtube Series about this lib.
• removed JitCI from production pipeline

01.00.03-RPM

• added JitCI for deployment as well
• version updates

01.00.02-RPM

• static <T, R> CheckedFunction<T, R> asCheckedFunc(Function<T, R> f)
• Converting.convertToString
• Converting.convertToInteger
• Converting.convertToDouble
• SystemProperties Util Functions
• Single

01.00.01-RPM

• BUGFIX in case, the result was calculated two times.

01.00.00-RPM

• defined it as final, as there was no big change since a long time using it in a bunch of projects
• JDK8 is used to create the jar
• module-info.java is available inside the folder _data

00.07.06-RPM

• parent pom update - version updates

00.07.05-RPM

• parent pom update - version updates
• added docker based deploy scripts

00.07.04-RPM

• switched to new version numbers format To make search/replace easier, I started with a new version format. 00.07.04-RPM ( -SNAPSHOT). The x.y.z is used in the same way, as before, but added RPM and leading zeros to make this format different from others. With this it is less possible to mix/change version numbers from other dependencies. A 0.7.4 could be used from different dependencies. ;-)
