[dna-issues] [JBoss JIRA] Closed: (DNA-196) Add methods to ValueFactory that takes Iterator<?> and returns Iterator<T>

[Randall Hauch (JIRA)]

     [ https://jira.jboss.org/jira/browse/DNA-196?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Randall Hauch closed DNA-196.
-----------------------------

    Resolution: Done


Added a single "create(Iterator<?> values):Iterator<T>" to the ValueFactory interface, and added implementation methods to all concrete classes.  The AbstractValueFactory class defines a ConvertingIterator<T> that wraps an Iterator<?> and simply calls "create(Object):T" on the value factory that is using it.  Thus, this method is actually quite efficient, since the only cost is the wrapped iterator instance.

> Since Property.getValues() returns Iterator<?>, ValueFactory should have methods that accept that Iterator<?> and returns an Iterator<T>.  This would make it easier to use the factory to get the value(s) out of a Property in the type that you want (without having to cast and with proper conversion if required).
