All, can I run more than one defaction in the开发者_如何学JAVA body of the rule? or can I only run one?
You can define as many actions in the pre
block of a rule as you want. You can have as many actions in the action block of a rule as you want (just enclose the action block in curly braces). For example,
rule first_rule {
select when pageview ".*" setting ()
pre {
notify_one = defaction() { notify("notify_one", "First defaction"); };
notify_two = defaction() { notify("notify_two", "Second defaction"); };
}
{
notify_one();
notify_two();
}
}
So I think the answer to your question is yes.
Your question is a little confusing, but I'll give it a run.
Running actions defined with defaction
is just like running system defined actions.
If you want to run more then one action in a rule, you need to wrap them in {} like so:
rule foo {
select when pageview ".*"
{
notify("cheese", "brie");
notify("apple", "golden delicious");
}
}
I seem to recall that a defaction has an implicit, optional 'pre' section, followed by the action(s). To include multiple actions you do need {} as Sam says.
act1 = defaction() {
{
notify("Defaction Demo", "<ul id='demo_id'></ul>");
append("#demo-id", "<li>cheese: brie</li>");
append("#demo-id", "<li>apple: golden delicious</li>");
}
};
That works out to defaction() { { ... } };
but the extra curly braces are required if you want more than one action in a defaction.
