Method Detail

decodePdu

public static Pdu decodePdu(io.netty.buffer.ByteBuf in)
                     throws IOException

Throws:

IOException

readObject

public static Object readObject(io.netty.buffer.ByteBuf dii)

normalizeParametersList

public static List<Object> normalizeParametersList(List<Object> parameters)

Ensure that every parameter matches the same type as when we are marshalling/unmarshalling it. This is useful for "local" mode: we do not want a different behaviour in local mode vs network mode and also we do not want unexpected JDBC parameter types on server-side processing.

Parameters:

parameters - the JDBC parameters

Returns:

a new list with converted JDBC parameters
