java - Why google-collections AbstractMultimap class use transient keyword for member variable? -


https://code.google.com/p/google-collections/source/browse/trunk/src/com/google/common/collect/abstractmultimap.java?r=117

abstractmultimap implements serializable.

in eyes actual datas saved map , totalsize variables.

but both variables declared transient keyword.

this fact means there's no serialization right?

private transient map<k, collection<v>> map; private transient int totalsize;

this fact means there's no serialization right?

no.

it means fields not serialized default serialization mechanism. state being serialized in writeobject() method ... of child class.
