CallRecords (Exonum Java Binding: Core 0.10.0 API)

java.lang.Object
- com.exonum.binding.core.blockchain.CallRecords

```
public final class CallRecords
extends Object
```
Provides information about call errors within a specific block.
This data type can be used to get information or build proofs that execution of a certain call ended up with a particular status.
Execution errors are preserved for transactions and before/after transaction handlers.
Use Blockchain.getCallRecords(long) to instantiate this class.
