java.lang.Object

net.openhft.chronicle.wire.WireMarshaller<T>

net.openhft.chronicle.wire.WireMarshallerForUnexpectedFields<T>

public class WireMarshallerForUnexpectedFields<T>
extends WireMarshaller<T>

This class extends the WireMarshaller and provides the ability to handle unexpected fields. It maps fields by their name (both in their original form and lower-cased) for easy access. It overrides the method to read marshallable objects and provides specialized logic to handle unexpected fields that might be present in the data source.

Method Detail

readMarshallable

public void readMarshallable(T t,
                             @NotNull
                             @NotNull WireIn in,
                             boolean overwrite)
                      throws net.openhft.chronicle.core.io.InvalidMarshallableException

Overrides the default deserialisation logic to handle unexpected fields. When a field name read from WireIn is not found in the known WireMarshaller.fields (even after case-insensitive matching), it calls ReadMarshallable.unexpectedField(Object, ValueIn) on object t if possible. Known fields are processed as usual. The check sb.length() == 0 && vin.isPresent() optimises for DTO-order field reading by using the next field directly. Ensures progress is made during parsing to avoid infinite loops.

Overrides:

readMarshallable in class WireMarshaller<T>

Parameters:

t - Object to populate with read values.

in - Input source from which values are read.

overwrite - Flag indicating whether to overwrite the existing value in the target object.

Throws:

net.openhft.chronicle.core.io.InvalidMarshallableException - If there is an error during marshalling.
