getSerializationContext

public ImmutableSerializationContext getSerializationContext()

Description copied from interface: MessageMarshaller.ProtoStreamReader

During reading, a marshaller can obtain the current ImmutableSerializationContext and use it in order to access the schema or marshaller information.

Specified by:

getSerializationContext in interface MessageMarshaller.ProtoStreamReader

readInt

public Integer readInt(String fieldName)
                throws IOException

Description copied from interface: MessageMarshaller.ProtoStreamReader

Reads an integer field given a field name. The field name and type are checked against the schema first. Can't return an int here because the field might be declared optional and actually missing so we have to be able to signal that by returning null.

Specified by:

readInt in interface MessageMarshaller.ProtoStreamReader

Throws:

IOException
