FailureConverter (temporal-sdk 1.22.1 API)

All Known Implementing Classes:

DefaultFailureConverter
```
public interface FailureConverter
```
A FailureConverter is responsible for converting from proto Failure instances to Java Exception, and back.
Most users should _never_ need to implement a failure converter. We strongly recommended relying on the DefaultFailureConverter, in order to maintain cross-language Failure serialization compatibility.
To _encrypt_ the content of failures, see CodecDataConverter instead.

```
Instantiate an appropriate Java Exception from a serialized Failure object.

Parameters:

failure - Failure protobuf object to deserialize into an exception

dataConverter - to be used to convert Failure#encodedAttributes and Failure#failure_info#details (if present).

Returns:

deserialized exception

Throws:

java.lang.NullPointerException - if either failure or dataConverter is null

```
Serialize an existing Java Exception into a Failure object.

Parameters:

throwable - A Java Exception object to serialize into a Failure protobuf object

dataConverter - to be used to convert Failure#encodedAttributes and Failure#failure_info#details (if present).

Returns:

serialized exception

Throws:

java.lang.NullPointerException - if either e or dataConverter is null
