java - How do I serialize a complex Class in GWT? -

i want serialize following class autobeans.

public class getresults<t extends dto> implements result {      list<t> results;      protected getresults() {     }      public getresults(list<t> results) {         this.results = results;     }      public list<t> getresults() {         return results;     }      public void setresults(list<t> results) {         this.results = results;     } } 

here tried failed:

public class autobeanserializer {     private final autobeanfactory factory;     public autobeanserializer(autobeanfactory factory) {         this.factory = factory;     }      public string <t> encodedata(t data) {         autobean<t> autobean = autobeanutils.getautobean(data);         return autobeancodex.encode(autobean);     }      public <t> t decodedata(class<t> datatype, string json) {         autobean<t> bean = autobeancodex.decode(factory, datatype, json);         return bean.as();     } } 

the above code not work line

public string encodedata(t data) {

has these errors:

- t cannot resolved type - type string not generic; cannot parameterized arguments   <t> 

how serialize above class abstract types in gwt?

you can use lib: https://code.google.com/p/gwt-streamer/

it job if implement streamable in classes.

here example documentation:

public class person implements streamable {     // fields, visibility doesn't matter     private string name;     private int age;      private person() {}        // default no-args constructor required      public person( string name, int age ) {         this.name = name; this.age = age;     }      // getters, setters optional... } 

server , client use same api serialization.

person person = new person( "anton", 33 ); string buffer = streamer.get().tostring( person ); //... person = (person) streamer.get().fromstring( buffer ); //... person personcopy = streamer.get().deepcopy( person );
