Method Detail

getSerializationType

abstract AbstractService.SerializationType getSerializationType()

Returns:

The manner in which the data is serialized.

finagle

Meta.Signature finagle(Meta.Signature signature)

Modifies a signature, changing the representation of numeric columns within it. This deals with the fact that JSON transmits a small long value, or a float which is a whole number, as an integer. Thus the accessors need be prepared to accept any numeric type.

finagle

ColumnMetaData finagle(ColumnMetaData column)

finagle

Service.PrepareResponse finagle(Service.PrepareResponse response)

finagle

Meta.StatementHandle finagle(Meta.StatementHandle h)

finagle

Service.ResultSetResponse finagle(Service.ResultSetResponse r)

finagle

Service.ExecuteResponse finagle(Service.ExecuteResponse r)

setRpcMetadata

public void setRpcMetadata(Service.RpcMetadataResponse metadata)

Description copied from interface: Service

Sets server-level metadata for RPCs. This includes information that is static across all RPCs.

Specified by:

setRpcMetadata in interface Service

Parameters:

metadata - The server-level metadata.
