Manuel Boillod commented on CAMEL-4004:
---------------------------------------

Sorry for the delay, but I can't provide a unit test, but I've given to you a 
patch in the description of this JIRA.

The solution is to externalize the FileConsumer creation into a new method 
which could be overloaded. 
Then you could use a different implementation of FileConsumer, like below:

{code}

public class PollConditionFileEndpont extends FileEndpoint {

    @Override
    protected FileConsumer newFileConsumer(Processor processor, FileOperations 
operations) {
        return new FileConsumer(this, processor, operations){
                @Override
                protected boolean prePollCheck() throws Exception {
                        return Boolean.parseBoolean("customizable condition");
                }
        };
    }

    
}
{code}

So, could you re-open this JIRA ?

Thanks

> The method FileEndPoint.createConsumer does not permit to override type of 
> FileConsumer. I would use a specific FileConsumer which override prePollCheck 
> method.
> This will be possible if you externalize method which create FileConsumer in 
> the body of createConsumer :
> {code}FileConsumer result = new FileConsumer(this, processor, 
> operations);{code}
> could be refactor in :
> {code}FileConsumer result = newFileConsumer(processor, operations);
> ...
> protected FileConsumer newFileConsumer(Processor processor, 
> GenericFileOperations<File> operations){
> return new FileConsumer(this, processor, operations)
> }{code}
