withLink() how to specify name/title/description?

[jamesladd]

How do you specify the name/title or description attributes of a Link using the
withLink methods of the builder?

James,

On the Resource interface there is a "full" argument method:

https://github.com/talios/halbuilder/blob/develop/src/main/java/com/theoryinpractise/halbuilder/spi/Resource.java

Resource withLink(String href, String rel,
Optional<Predicate> predicate, Optional name,
Optional title, Optional hreflang);

This lets you add a name, title, lang and predicate as optionals. It's
not as pretty as I'd like but without real optional arguments I'd end up
with endless permutations.

Re: the last email - looks like I added the URI based variations of the
withLink methods awhile ago as additional overloaded methods.

Mark,

Im not sure how to call the method - do you have an example?

BTW - you could make the withLink method a var args when you get to the
optional elements, then assume they are specific args based on count and
position.

The Optional class is from Google Guava and can be created via:

Optional.of(something) for a "this is not null" result or:
Optional.fromNullable(somethingThatMayBeNull) which will return an
absent Optional if null, or finally:
Optional.absent() for an optional that dosn't exist.

The vararg idea is interesting, I have an idea of doing that in a nice
position independent way as well.

How do I do the predicate argument?

With the other attributes you could return builders for those too.
WithLink().withName() etc

Predicate is another Guava interface:

http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/base/Predicates.html

A Predicate has one method called apply(T t) which simply returns
true/false.

I'm using it in HalBuilder to provide a means of doing conditional
links.
