PossibleExceptionFromMetadata (Interlok Core/Base)

java.lang.Object
- com.adaptris.core.services.exception.ExceptionFromMetadataImpl
- - com.adaptris.core.services.exception.PossibleExceptionFromMetadata

All Implemented Interfaces:

ExceptionGenerator
```
public class PossibleExceptionFromMetadata
extends ExceptionFromMetadataImpl
```
ExceptionGenerator implementation that generates the exception from metadata.
Use this class with ThrowExceptionService to throw an exception as part of a workflow. The exception message (i.e. Throwable.getMessage()) is derived from the configured metadata key. If the metadata key does not exist (or returns no value) then no exception will be thrown. This behaviour differs from ExceptionFromMetadata

In the adapter configuration file this class is aliased as possible-exception-from-metadata which is the preferred alternative to the fully qualified classname when building your configuration.
