Improve Map support for JCR Node based Resources
------------------------------------------------
Key: SLING-557
URL: https://issues.apache.org/jira/browse/SLING-557
Project: Sling
Issue Type: Improvement
Components: JCR Resource
Affects Versions: Scripting API 2.0.2, JCR Resource 2.0.2
Reporter: Felix Meschberger
Assignee: Felix Meschberger
SLING-395 added support for adapting a JCR-Node based resource to a Map. This
first implementation converts property values to their Java equivalent as per
the JSR-170 specification.
As the JCR Value interface also allows on-the-fly conversion of values, it
would be helpfull for the Map adapter to also support this kind of on-the-fly
conversion. See also the discussion on [1]
This issue will introduce a new interface to the Sling API:
package org.apache.sling.api.resource;
public interface ValueMap extends Map<String, Object> {
// returns the named value or null if not existing
@Overwrite
Object get(String name);
// return named value converted to type T or
// null if not existing
<T> T get(String name, Class<T> type);
// return named value converted to the type T of
// the default value or the default value if the
// named value does not exist
<T> T get(String name, T defaultValue);
}
This interface will be implemented for JCR-Node based Resources
