Class WireRowsDeserializer

java.lang.Object
tools.jackson.databind.ValueDeserializer<List<List<Object>>>
dev.frostlake.http.WireRowsDeserializer
All Implemented Interfaces:
tools.jackson.databind.deser.NullValueProvider
public final class WireRowsDeserializer extends tools.jackson.databind.ValueDeserializer<List<List<Object>>>
Reads a response's rows off the wire token by token, so a number's own text decides its Java form. An integer token is the reader's integer; a fraction is a BigDecimal exact to the digit, which is what keeps a NUMBER(38,20) exact across the transport; and a fraction spelled with a minus sign whose value is zero is a FLOAT's negative zero, the one number a BigDecimal cannot hold, so it comes back as the double -0.0. A tree read would have dropped that sign before the client could see the column was a FLOAT; the client still re-types every FLOAT cell from the column metadata afterwards, so nothing else here needs the type. Anything that is not a scalar token is read the way the mapper reads any untyped value.
