msakamoto-sf / groovy_enum_metaClass_demo1.groovy
Last active December 20, 2015 18:19
Groovy and enum demo. Groovy 1.8.9 doesn't suport enum's abstract method, but static initializer and metaClass makes nealy likely enable it. This is a work arround for http://jira.codehaus.org/browse/GROOVY-4641
// tested on Groovy 1.8.9.
enum GreetEnum {
MORNING("Good Morning"),
AFTERNOON("Good Afternoon"),
EVENING("Good Evening");
static {
MORNING.metaClass.greeting = { String you ->
return delegate.emphasize() + " " + you + ", I'm sleeping..."
}

JavaMail + Groovy samples.

GroovyでJavaMailの使い方を勉強した時のサンプルコードです。 基本的に JavaMailでのメール送信まとめその１ - あられねこのめも をGroovyでちょこっと手直しした感じのものになります。

サンプルコードの解説

01 - 09 まではひたすらMimeMessageを元にしたメッセージの組み立て方の勉強です。
