CheckFileExistsOperation (interlok-aws-s3 4.4-SNAPSHOT API)

java.lang.Object
- com.adaptris.aws.s3.S3OperationImpl
- - com.adaptris.aws.s3.ObjectOperationImpl
  - - com.adaptris.aws.s3.CheckFileExistsOperation

All Implemented Interfaces:

S3Operation, ComponentLifecycleExtension
```
@ComponentProfile(summary="Check a file exists in S3, throws exception if it doesn\'t",
                  since="3.8.4")
public class CheckFileExistsOperation
extends ObjectOperationImpl
```
Check an exists in S3 and throw an exception if it doesn't.
Note that this component will throw an exception if the file does not exist possibly cascading into a failed message; you probably want to use something like ExceptionHandlingServiceWrapper or similar if a missing S3 object is part of your expected integration pipeline.

In the adapter configuration file this class is aliased as amazon-s3-check-file-exists which is the preferred alternative to the fully qualified classname when building your configuration.
