[Simple-support] Reusing XML elements

[Sobeos <so...@gm...>]

I'm reusing XML elements in my xml based on the id ref machanism which is
working fine. 

http://simple.sourceforge.net/download/stream/doc/tutorial/tutorial.php#reus
e

 

Now I want to unmarshall the id attribute as a normal member variable. As
result I get always 0. 

Is there a way to get the value of id in the java object when using final
Strategy strategy = new CycleStrategy("id", "ref");?

 

Any ideas/hints?

Re: [Simple-support] How can I make Simple not to serialize empty ArrayList?

[Niall G. <gal...@ya...>]

You can use a converter, it should be able to remove the tag. The problem here is how do you distinguish null from an empty list. The tag is needed for this in order to do a verbatim serialization/deserialization.

       Good day, I need an advice please. let's say I
 have class
         Person:
       @Root(name="Person")
 public class Person {
 
   @Element(name="Name")
   public String name = "MyName"
 
   @ElementList(name="AddressList", entry="Address", required=false)
   public ArrayList<Address> addressList = new ArrayList<>();
 
 }
       ... and class Address:
       public class Address {
 
   @Element(name="Street")
   public String street;
 
   @Element(name="City")
   public String city;
 }
       When addressList has no items Simple produces this
 XML:
       <Person>
   <Name>MyName</Name>
   <AddressList/>
 </Person>
       Please, how can I make Simple omit tag
 AddressList
         if there are no items on the list? I want the XML
 look like this
         in such case:
       <Person>
   <Name>MyName</Name>
 </Person>
        I don't want to set the addressList to null.
 When I create
         Person object I want the addressList to be
 initialized so that I
         can easily add addresses if needed and I don't
 need to check
         whehter it is null and instantiate it. The example
 above is very
         simple but when my object hierarchy is more
 complicated it is
         unconvenient to check and initialize all lists. I
 hoped I could
         resolve it using some anotation or custom converter
 or something
         like that.
 
       
       Thank you in advance. Vojta

[Simple-support] How can I make Simple not to serialize empty ArrayList?

[Vojtěch R. <ry...@ce...>]

Good day, I need an advice please. let's say I have class Person:

|@Root(name="Person")
public  class  Person  {

   @Element(name="Name")
   public  String  name=  "MyName"

   @ElementList(name="AddressList",  entry="Address",  required=false)
   public  ArrayList<Address>  addressList=  new  ArrayList<>();

}|

... and class Address:

|public  class  Address  {

   @Element(name="Street")
   public  String  street;

   @Element(name="City")
   public  String  city;
}|

When addressList has no items Simple produces this XML:

|<Person>
   <Name>MyName</Name>
   <AddressList/>
</Person>|

Please, how can I make Simple omit tag *AddressList* if there are no 
items on the list? I want the XML look like this in such case:

|<Person>
   <Name>MyName</Name>
</Person>|

I don't want to set the addressList to null. When I create Person object 
I want the addressList to be initialized so that I can easily add 
addresses if needed and I don't need to check whehter it is null and

I think I mentioned that non-static inners cannot be instantiated via reflection, it has an implicit "this"...

Re: [Simple-support] Serializing java.util.Set<Enum>

[Niall G. - Y. <Nia...@yi...>]

Try public static enum, reflection does not deal well with non static inners. Apart from that it should serialize fine.

You cannot construct a non static inner class through reflection. For the constructors also you must specify the names

[Simple-support] Writing to XML fails

[Miha V. <mih...@gm...>]

Hi Niall,

first off, thanks for the great library. But I'm having trouble fitting 
the following together:

package com.mycompany.simpletest;

import org.simpleframework.xml.Element;
import org.simpleframework.xml.Root;

@Root(name = "pair")
public class Pair<A, B> {
     @Element
     private final A first;
     @Element
     private final B second;

     public Pair(A first, B second) {
         this.first = first;
         this.second = second;
     }

     public A getFirst() { return first; }

     public B getSecond() { return second; }
}
------------------
package com.mycompany.simpletest;

import java.util.ArrayList;
import java.util.List;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.ElementList;
import org.simpleframework.xml.Root;

@Root(name = "test")
public class Test {

     @Root(name = "element1")
     public class Info {
         @Element
         private String name;

         public Info(String name) {
             this.name = name;
         }
     }

     @ElementList(name = "list")
     private List<Pair<Info, Info>> list;

     public Test() {
         list = new ArrayList<>();
     }

     public void add(String s1, String s2) {
         Info i1 = new Info(s1);
         Info i2 = new Info(s2);
         Pair<Info, Info> p = new Pair<>(i1, i2);
         list.add(p);
     }
}
------------------
package com.mycompany.simpletest;

import java.io.FileOutputStream;
import org.simpleframework.xml.Serializer;
import org.simpleframework.xml.convert.AnnotationStrategy;
import org.simpleframework.xml.core.Persister;
import org.simpleframework.xml.strategy.Strategy;

public class SimpleTest {

     public static void main(String[] args) {
         Test t1 = new Test();
         t1.add("a", "b");
         t1.add("b", "c");

         try {
             FileOutputStream out = new FileOutputStream("test.xml");

             Strategy strategy = new AnnotationStrategy();
             Serializer serializer = new Persister(strategy);
             serializer.write(t1, out);


             out.close();
         } catch (Exception e) {
             e.printStackTrace();
         }
     }
}

Re: [Simple-support] Does SimpleXML have its own version of 'XJC'?

[dennis <de...@li...>]

Hi Roger,

Some time ago I posted a sed script to convert the java classes output of 
xjc to something that works with SimpleXML. I have attached the scripts
in case you or anyone else is interested. I made some updates during 
my conversations with Kyle and others. I didn't keep up with new Simple
developments for a while, so new concepts may need some fidling.

See: http://sourceforge.net/p/simple/mailman/message/29161101/

The script works as follows (tested on Ubuntu Linux some time ago):
- generate source with xjc: xjc XMLSchema.xsd
- jaxb2simple.sed generated/JAXBSource.java >
  src/generated/SimpleSource.java
- or in batch with the rewrite script:
    NAMESPACE=generated
    cd $NAMESPACE
    for i in *.java ;do ../../rewrite.sh $i ../$NAMESPACE/ddi/$i ;done

The generated code can now be used on android with simple. Some things may
need to be fixed, since I didn't test yet with an XSD covering all concepts,
and because simpleframework defaults to require all elements (opposed to
jaxb). Expect fixes for emply lists, and enumerations of strings (Android
does not seem to return valueOf correctly when casing of remaining
letters does not match enum name).

Kind regards,
Dennis

Re: [Simple-support] Does SimpleXML have its own version of 'XJC'?

[Niall G. - Y. <Nia...@yi...>]

Hi,

There is currently no tool to generate java classes. However a simple search and replace of JAXB annotations on any generated code should be workable.

Re: [Simple-support] Multiple Elements with same name, different Attributes

[Boris G. <bo...@gl...>]

Hi Niall

Thank you for your really,  so would i need converter on userInfo or on 
address?

Also is there a good sample for this, i am kind of new to Java.

UserInfo contains much more info witch get deserialized  just fine, it 
just address i need to get Address in to the right variable depending on 
Attribute.

Thank you.

Boris

Hi,

You would have to write a Converter for this. This requires you implement

[Simple-support] @Path and @Attribnute

[Tomáš P. <tom...@at...>]

I have small problem

I have this XML

<Statistics>
<SummaryReservations Count="34">
 <Filter>
<FilterByType Count="34"/>
<FilterByDateLimit Count="6"/>
 <FilterByAll Count="6"/>
</Filter>
</SummaryReservations>
 </Statistics>


And thiss class

public class Statistics {

@Path("SummaryReservations")
@Attribute(name = "Count")
int summaryRservationsCount;

@Path("Filter/FilterByType")
@Attribute(name = "Count")
int filterByTypeCount;

@Path("Filter/FilterByDateLimit")
@Attribute(name = "Count")
int filterByDateLimitCount;

@Path("Filter/FilterByAll")
@Attribute(name = "Count")
int filterByAllCount;

But only summaryRservationsCount is filled, all other fields stay at 0
Do somebody know why?

[Simple-support] Maps with inline values; default values

[Paul J. <pa...@pa...>]

Hi,

Thanks for the tips so far. For most of the issues I raised I now have
workarounds that will suffice. And I'm going to investigate JSON
serialisation shortly.

However, there are two issues that I still need some help with:

1) Maps with inline values

If I have a field like this:
    @ElementMap(inline=true, attribute=true)
    Map<String,VarInfo> sinks = new HashMap<String,VarInfo>();

It produces XML like this:
   <entry key="xss">
      <varInfo>
         <field>jim</field>
         <field2>bob</field2>
      </varInfo>
   </entry>

I want XML like this:
  <varInfo key="xss">
     <field>jim</field>
     <field2>bob</field2>
  </varInfo>

I did propose a hack to write this correctly, but it breaks reading - and I
can't see how to fix that. Also, there is a teasing note in Entry.java
saying "value objects can be written inline if desired" - so I think there
is a way to do it, I've just not figured it out yet.

2) Default values

I want to have a field like:

    @Attribute(default=true)
    boolean myField;

Now, when writing, if myField is true, then I want to skip the field. And
when reading, if the attribute it missing, I want to use the default value.
Note that "empty" does NOT have these semantics.

I realise this is probably a new feature, but it would be extremely helpful
to me, in keeping the generated XML concise. I have considered putting this
at other parts in my app (e.g. just letting myField be null and handling
that appropriately) but it really would help to have Simple do this.

Any input would be appreciated,

Re: [Simple-support] Dynamically turn off strict mode

[Lumsdon, H. <Hug...@bl...>]

Hi Niall,

We want to ignore every element - so a converter isn't practical.

Actually I was thinking that, unless I'm completely misunderstanding things, the version annotation / attribute pretty much does what we want - however I'd rather leave this for actual versioning.  Having a similar root attribute that is just a Boolean would be good.

Thanks.

Hi,

I am afraid there is no way to do this. The only thing I could suggest is to use a converter for the parts you want to parse in non-strict way.

 Hi, 
    
 We’re after a way to turn
 off strict mode dynamically, based on an attribute in the  root element of the source XML document. e.g. 
    
 <contentType
 dummy=”true”> 
    
    
 i.e. if the “dummy”
 attribute is set to true we want to be able to make all  fields / attributes optional – equivalent to called  Serializer.read(x,x, false) – but  dynamically. 
    
 Any suggestions how best to do
 this? 
    
 Thanks,
 Hugo.

Re: [Simple-support] Default converter & default values

[Niall G. - Y. <Nia...@yi...>]

There is no DefaultConverter nor is there ever likely to be, one thing you can do with a converter which may help is you can give it a reference to the Serializer and push through objects again with the outputnode or inputnode. There are examples in the test cases of this. There is also an empty attribute on @Text and @Attribute that can set defaults.

   /**
    * This is used to provide a default value for the attribute if
    * the annotated field or method is null. This ensures the the
    * serialization process writes the attribute with a value even
    * if the value is null, and allows deserialization to determine
    * whether the value within the object was null or not.
    *
    * @return this returns the default attribute value to use
    */
   String empty() default "";

Subject: [Simple-support] Default converter & default values

Hi,

Thanks for the tips on JSON. I haven't looked into them just yet; will do shortly. In the meantime, I have a couple more questions:

1) Is there a DefaultConverter I can inherit from?

When writing a Converter I often find I only want to explicitly set an attribute or two, and would otherwise like to use the default conversion behaviour. It would be helpful if I could subclass something like DefaultConverter and call super.write() when I need.

I'm aware that I can kind of get this behaviour using a Strategy - in fact, that's what I'm doing now. But I'd prefer to use a Converter because then I can keep serialisation logic with the class that is being serialised, rather than having a central serialisation class.

2) Is there a way to have default values?

I have a few classes with a number of boolean attributes. 95% of the time these fields are at their default value and it would make the XML much more concise to omit them. The semantics I'd like are that when writing, the node is only generated if the value does not match the default. And when reading, if the node is not present, then the default is used.

Any hints appreciated,

Paul
