I am new to functional programming paradigm and hoping to learn the concepts using groovy. I have a json text containing a list of several person objects like the following:
{
"persons":[
{
"id":1234,
"lastname":"Smith",
"firstname":"John"
},
{
"id":1235,
"lastname":"Lee",
"firstname":"Tommy"
}
]
}
What I am trying to do store them in list or array of Person groovy class like the following:
class Person {
def id
String lastname
String firstname
}
I would like to do this using a closure. I tried something like:
def personsListJson= new JsonSlurper().parseText(personJsonText) //personJsonText is raw json string
persons = personsListJson.collect{
new Person(
id:it.id, firstname:it.firstname, lastname:it.lastname)
}
This didn't work. Does collect operations supposed to behave this way? If so then how do I write it?
