Patrik Mihalčin :
What is Groovy's alternative for Java 8's .map()?
Example:
List<String> codes = events
.stream()
.map(event -> event.getCode())
.collect(Collectors.toList());
I was trying to do
events.each { it; return it.getCode() }.collect() as String[]
but I am getting List of Strings, but toString() representation instead of code
Michael Easter :
Consider the collect method as illustrated below:
class Event {
def code
def name
}
def events = []
events << new Event(code: '001', name: 'a')
events << new Event(code: '002', name: 'b')
def codes = events.collect { it.code }
assert ['001','002'] == codes
