groovy closure parameters
- by Don
Hi,
The following example of using the sendMail method provided by the grails mail plugin appears in this book.
sendMail {
to "foo@example.org"
subject "Registration Complete"
body view:"/foo/bar", model:[user:new User()]
}
I understand that the code within {} is a closure that is passed to sendMail as a parameter. I also understand that to, subject and body are method calls.
I'm trying to figure out what the code that implements the sendMail method would look like, and my best guess is something like this:
MailService {
String subject
String recipient
String view
def model
sendMail(closure) {
closure.call()
// Code to send the mail now that all the
// various properties have been set
}
to(recipient) {
this.recipient = recipient
}
subject(subject) {
this.subject = subject;
}
body(view, model) {
this.view = view
this.model = model
}
}
Is this reasonable, or am I missing something? In particular, are the methods invokedwithin the closure (to, subject, body), necessarily members of the same class as sendMail?
Thanks,
Don
