# java-async-generator
A Java version of Javascript async generator.
Idea is to create an iterator-like interface that emit elements as [CompletableFuture] ( the Java counterpart of Javascript Promise ) enabling asynchronous iteration over data
# Releases
**Note: ‼️**
> From release 3.0.0 the miminum supported Java version is the `Java 17` and
> will not be longer available the artifact `async-generator-jdk8`
# Samples
## Create an Async Generator to make multiple API calls
```java
AsyncGenerator makeMultipleApiCalls(List requestsData) {
return AsyncGenerator.map(requestsData, requestData -> {
CompletableFuture res = asyncApiCall( requestData );
return res;
});
}
List resquestsData = ....
// can iterate using lambda function (Consumer)
makeMultipleApiCalls( resquestsData )
.forEachAsync( response -> logger.info( "Api response: " + response ) )
.join();
// can iterate using classic for( : )
AsyncGenerator generator = makeMultipleApiCalls( resquestsData );
for( Response response : generator ) {
logger.info( "Api response: " + response )
}
```
