[ https://issues.apache.org/jira/browse/QPID-6603?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Keith Wall updated QPID-6603:
-----------------------------
Summary: Allow model to express that an attribute is immutable (was: Allow model to express that an attribute is immuable)
> Allow model to express that an attribute is immutable
> -----------------------------------------------------
>
> Key: QPID-6603
> URL: https://issues.apache.org/jira/browse/QPID-6603
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Keith Wall
> Fix For: qpid-java-6.0
>
>
> We have a number of instances in the Java Broker's model where attribute values are fixed after a model object is constructed. Common examples are id, durable, type.
> This is currently enforced with repetitive code in the object's #validateChange method. It will be a useful extension to the model if immutability could be expressed via the managed attribute annotation thus allow the code enforcing immutability made generic.
> In addition, the metadata service should expose the immutable to the UI, allowing the UI to automatically render readonly widgets.
