Class CallRecords

java.lang.Object

com.exonum.binding.core.blockchain.CallRecords

public final class CallRecords
extends java.lang.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.

Method Summary

Modifier and Type	Method	Description
java.util.Optional<Errors.ExecutionError>	get(Blockchain.CallInBlock callInBlock)	Finds the error, if any, occurred in the given call.
java.util.Map<Blockchain.CallInBlock,Errors.ExecutionError>	getErrors()	Returns all errors in the block.
Proofs.CallProof	getProof(Blockchain.CallInBlock callInBlock)	Returns a cryptographic proof of authenticity for a top-level call within a block.
