     --function.name=uppercase
     --function.code="f -> f.map(s -> s.toString().toUpperCase())"

Example REST Application:

java -jar spring-cloud-function-web-1.0.0.BUILD-SNAPSHOT.jar
     --web.path=/demo
     --function.name=uppercase

Using Scripts:

FUN="f->f.map(s->s.toString().toUpperCase())"

./stream.fun -i words -o uppercaseWords -f $FUN

./web.fun -p /words -f $FUN
