Lukas Eder created JCR-3555:
-------------------------------
Summary: Add a static utility to transform JCR Iterators into
Iterables
Key: JCR-3555
URL: https://issues.apache.org/jira/browse/JCR-3555
Project: Jackrabbit Content Repository
Issue Type: Improvement
Components: jackrabbit-jcr-commons
Affects Versions: 2.6
Reporter: Lukas Eder
Priority: Minor
Attachments: Iterators.java.patch
I have stumbled upon the utility classes in the
org.apache.jackrabbit.commons.iterator package. They're quite useful in
principle, but not applied thoroughly. E.g. there are missing wrapper types for
at least these JCR Iterators:
- AccessControlPolicyIterator
- EventIterator
- EventListenerIterator
- NodeTypeIterator
- VersionIterator
Instead of adding more classes, it might be useful to create static methods for
the job. Using static methods from a single class (with static imports) is a
bit more convenient than looking up and creating the wrapper types using "new
WrapperType(...)"
An example:
org.apache.jackrabbit.commons.iterator.Iterators.iterable
// And then:
for (Node n : iterable(parent.getNodes())) {
// Do stuff with n
}
Please find attached a .patch file containing an implementation suggestion.
