CompositeTSPSource (Digital Signature Services 5.5 API)

java.lang.Object
- eu.europa.esig.dss.spi.x509.tsp.CompositeTSPSource

All Implemented Interfaces:

TSPSource, Serializable
```
public class CompositeTSPSource
extends Object
implements TSPSource
```
This class allows to retrieve a timestamp with different sources. The composite will try all sources until to get a non-empty response. Be careful, all given tspSources MUST accept the same digest algorithm.
