Method Details

getContractId

@Nullable
public ContractId getContractId()

Extract the contract id.

Returns:

the contract id

setContractId

public ContractByteCodeQuery setContractId(ContractId contractId)

Sets the contract ID for which information is requested.

Parameters:

contractId - The ContractId to be set

Returns:

this

validateChecksums

void validateChecksums(Client client)
                throws BadEntityIdException

Description copied from class: Query

Validate the checksums.

Specified by:

validateChecksums in class Query<com.google.protobuf.ByteString,ContractByteCodeQuery>

Throws:

BadEntityIdException

onMakeRequest

void onMakeRequest(Query.Builder queryBuilder,
 QueryHeader header)

Description copied from class: Query

Called in Query.makeRequest() just before the query is built. The intent is for the derived class to assign their data variant to the query.

Specified by:

onMakeRequest in class Query<com.google.protobuf.ByteString,ContractByteCodeQuery>

mapResponseHeader

ResponseHeader mapResponseHeader(Response response)

Description copied from class: Query

The derived class should access its response header and return.

Specified by:

mapResponseHeader in class Query<com.google.protobuf.ByteString,ContractByteCodeQuery>

mapRequestHeader

QueryHeader mapRequestHeader(Query request)

Description copied from class: Query

The derived class should access its request header and return.

Specified by:

mapRequestHeader in class Query<com.google.protobuf.ByteString,ContractByteCodeQuery>

mapResponse

com.google.protobuf.ByteString mapResponse(Response response,
 AccountId nodeId,
 Query request)

Description copied from class: Executable

Called after receiving the query response from Hedera. The derived class should map into its output type.

Specified by:

mapResponse in class Executable<ContractByteCodeQuery,Query,Response,com.google.protobuf.ByteString>

getMethodDescriptor

io.grpc.MethodDescriptor<Query,Response> getMethodDescriptor()

Description copied from class: Executable

Called to direct the invocation of the query to the appropriate gRPC service.

Specified by:

getMethodDescriptor in class Executable<ContractByteCodeQuery,Query,Response,com.google.protobuf.ByteString>
