------------------------------------------
> Velocity should provide an interface for explicit property retreival
> --------------------------------------------------------------------
>
> Key: VELOCITY-31
> URL: https://issues.apache.org/jira/browse/VELOCITY-31
> Project: Velocity
> Issue Type: Bug
> Components: Anakia
> Affects Versions: 1.1-rc2
> Environment: Operating System: All
> Platform: All
> Reporter: lev epshteyn
> Assigned To: Velocity-Dev List
>
> I think that there should be an interface with a method of something like
> Object
> getVelocityProperty(String key);
> that will provide for a way to manually determine what
> object to retrieve with a given property name. Currently, there is no good
> way to access hashtable-
> like structures without resorting to what essentially amounts to putting java
> code into the
> template. (i.e. "$hash.get($key)")...
> Velocity should allow developers to implement an
> interface to get more control of velocity engine rendering, so that when the
> template calls for
> $obj.property, a check is made to see if an object is an instance of that
> interface. If not, the
> standard algorithm should be used to determine if this object has a
> getProperty() method. But if
> the object does implement the interface, Velocity would call
> getVelocityProperty("property") on it, and it would be up to the programmer
> to provide proper
> logic to return the property. (in a Hashtable wrapper, the method would
> contain one line:
> return hash.get(key);
> This will not only give the programmer more control and force
> them to pur less Java code into the template, but would also enable the
> developer to optimize the
> most frequently accessed types of objects for performance as it will reduce
> the need to perform
> reflection lookups.
