Extend Resource interface and provide AbstractResource base class
-----------------------------------------------------------------
Key: SLING-1193
URL: https://issues.apache.org/jira/browse/SLING-1193
Project: Sling
Issue Type: New Feature
Components: API
Affects Versions: API 2.0.8
Reporter: Felix Meschberger
Fix For: API 2.0.10
Currently the Resource interface has only bare bones API to access its own
local attributes, like getPath() or getResourceType().
Accessing the resource in the context of its parent or its children is not
currently possible and doing so requires getting the resource resolver out of
the resource and asking the resource resolver.
For convenience, we should add the following methods:
getParent() -- returns the parent resource (same as
ResourceUtil.getParent(this))
getName() -- returns the name of the resource (same as
ResourceUtil.getName(this))
listChildren() -- same as getResourceResolver().listChildren(this)
getChild(String) -- same as getResourceResolver().getResource(this, path)
isResourceType(String) -- same as ResourceUtil.isA(this, String)
The new AbstractResource class will implement these methods as indicated.
Implementors of the Resource interface are then advised to actually extend from
the AbstractResource interface, which in the future will provide default
implementations of any methods added to the Resource interface, if it makes
sense.
