B.9.2. Internal Externalizer Implementation Access
Externalizable objects should not access Red Hat JBoss Data Grids Externalizer implementations. The following is an example of incorrect usage:
public static class ABCMarshallingExternalizer implements AdvancedExternalizer<ABCMarshalling> {
@Override
public void writeObject(ObjectOutput output, ABCMarshalling object) throws IOException {
MapExternalizer ma = new MapExternalizer();
ma.writeObject(output, object.getMap());
}
@Override
public ABCMarshalling readObject(ObjectInput input) throws IOException, ClassNotFoundException {
ABCMarshalling hi = new ABCMarshalling();
MapExternalizer ma = new MapExternalizer();
hi.setMap((ConcurrentHashMap<Long, Long>) ma.readObject(input));
return hi;
}
...
End user externalizers do not need to interact with internal externalizer classes. The following is an example of correct usage:
public static class ABCMarshallingExternalizer implements AdvancedExternalizer<ABCMarshalling> {
@Override
public void writeObject(ObjectOutput output, ABCMarshalling object) throws IOException {
output.writeObject(object.getMap());
}
@Override
public ABCMarshalling readObject(ObjectInput input) throws IOException, ClassNotFoundException {
ABCMarshalling hi = new ABCMarshalling();
hi.setMap((ConcurrentHashMap<Long, Long>) input.readObject());
return hi;
}
...
}
