[Simple-support] any performance tricks?

[Jim S. <ji...@fu...>]

Hi,

I'm evaluating Simple along with some other tools that will serialize 
data for purposes of data transfer across a network. I much prefer the 
annotations-based way that Simple lets me prepare data for serialization 
to the other tool I'm evaluating (Google protobuf), but the performance 
is becoming a determining factor. For example, a sample data structure 
which takes 1.53ms to encode with Simple only takes 0.048ms to encode 
with protobuf.

I'm just doing a very simple standard annotation markup with @Attribute 
and @Element (the outer structure has a dozen fields and a list of two 
inner structures, each having about a half-dozen fields). Then I just 
use persister.write to serialize.

I'm guessing maybe the reflection is taking a lot of time?  Not sure. 
But are there any known performance tips/tricks to know about with Simple?

Thanks,

Jim

Re: [Simple-support] Problem with override

[saurabh s. <sau...@ya...>]

One way to achieve this is on the same lines of JAXB.

You can have an annotation like this:

@ElementRef(class="<comma-separared list of all the implementing classes>"). Now when you serialize, you can use the name of the actual implementing class itself that is contained within the vairable or use the name from the annotation on that class.

While deserializing, you can match the name of the tag from the xml to a name from the list or their annotations and create an instance of the actual implementing class.

E.g

public
    @ElementRef(class="Impl1.class, Impl2.class")
    public Iface iface;
}
public class Impl1 implements Iface {
}
public class Impl2 implementsIface {Regards,
}
 
XML - 1:
 <?
<xml version="1.0" encoding="UTF-8"?>root>
<impl1></impl1>root>
</
 
XML - 2:
 <?
<xml version="1.0" encoding="UTF-8"?>root>
<impl2></impl2>root>
</
  class Root {

Hi,

Actually, you are right, it will call all instances "reference". Did not see the different types mentioned. Here the problem is how to match the element with the field. If the names do not match, either by field name or by the name attribute on the annotation then there is no real way to match the element or attribute with the field or method.

However, I welcome any proposals for how to do this, either via an extra annotation or some other scheme.

Thanks,
Niall

Hi,
But this solution will always serialize the Formula to "reference", am I right?
What if one wants to have "reference" , "constant" or "function" depending on the actual implementation?
Is this possible?

Regards,
Saurabh.

Hi,

Just name the @Element like so.

@Element(name="reference")
Formula formula;

This will serialize the Formula class as "reference".

Hope this helps,
Niall

Hi,
I’m trying to serialize a class similar to this one:
 
publicclassBinding {
      
      @Attribute
      privateType type;
      
      @Attribute
      privateString name;
      
      @Attribute
      privateSide side;
      
      @Attribute(required=false)
      privateString part;
      
      @Element
      privateFormula formula;
...
}
 
Where Formula is an interface implemented by three classes: Constant, Function and Reference. For instance, I have annotated the Reference class, like that:
 
publicclassReference implementsFormula {
      
      @Attribute
      privateString activity;
      
      @Attribute
      privateType type;
      
      @Attribute
      privateString name;
      
      @Attribute
      privateSide side;
...
}
 
When the Binding class is serialized the following xml file is produced:
<bindingtype="NORMAL" name="par21" side="IN">
        <formulaclass="com.tilab.wemash.model.Reference" activity="webServiceActivity1" type="NORMAL" name="par11" side="OUT"/>
</binding>
 
I would like to know if it there is any way to produce, instead, the following xml:
<bindingtype="NORMAL" name="par21" side="IN">
        <referenceclass="com.tilab.wemash.model.Reference" activity="webServiceActivity1" type="NORMAL" name="par11" side="OUT"/>
</binding>
 
That is: when the element formula of the Binding is serialized, I want that the name of the class Reference is used as element name instead of the name of the interface implemented by the class Reference.

Giovanna

Re: [Simple-support] Avoiding NullPointerException

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

Hi,

If you could send me a test case that would be great. Empty elements are null in Simple. There is an empty= attribute on @Attribute and @Text which let you specify a substitute to null. For example

@Attribute(empty="[NULL]")
private String name;

This will mean an attribute of 

<element name="[NULL]">

Will deserialize the attribute name null. Also text like

@Text(empty="This is null")
private String value;

<text>This is null</text>

Will deserialize to null. However there is no such setting for a value in a map. I would greatly appreciate it if you could supply a test case to help me improve the overall stability of the project. Looks like an edge case around representing primitives as java.lang.Object again.

Thanks,
Niall

[Simple-support] Avoiding NullPointerException

[Alan D. <Ala...@zn...>]

Niall,

Thanks for the recent update to 2.0.3.   It wasn't holding me up but it is great to get past that problem.

On to something else:  I think this has been discussed before, but I couldn't find it in the archives.  It has to do with serializing the empty String value: "".  When reading it back in, you get a NullPointerException if the element is not marked required=false.

So how do we deal with that in a collection?   My test case produces the following document:

<simpleBug1 id="0">
   <test1 id="1">
      <data id="2">
         <entry>
            <string id="3">key1</string>
            <object class="java.lang.String" id="4">value</object>
         </entry>
         <entry>
            <string id="5">key2</string>
            <object class="java.lang.String" id="6"></object>
         </entry>
      </data>
   </test1>
</simpleBug1>

Reading it back in gets:

	Exception: java.lang.NullPointerException
	java.lang.NullPointerException
        	at org.simpleframework.xml.core.Traverser.read(Traverser.java:79)
        	at org.simpleframework.xml.core.CompositeValue.read(CompositeValue.java:102)
        	at org.simpleframework.xml.core.CompositeMap.populate(CompositeMap.java:177)

etc.  If you want me to send you the test case let me know, but again I don't know if this is a problem with simple or something I sould be doing but ain't.  Thanks again.

Re: [Simple-support] De-serialization problem -- valid referencenot valid?

[<Nia...@ub...>]

Hi,

Yes this is a bug that was introduced with a recent enhancement to be
able to write primitives from Object fields and  also mix primitives
within a list or map. I have resolved the issue and will release a minor
version tonight with the fix. 2.0.3.

Thanks for the feedback,
Niall

OK, I think I have test case for you in the attached file.   The program 
run without a command-line parameter will write the file 
"SimpleBug.xml".   If you run it with the command line parameter "-r" it 
will try to read that file, with the exception.   The exception I got was:

    org.simpleframework.xml.graph.CycleException: Invalid reference '4' 
found

The file it should generate (but can't read) looks like this:

<simpleBug id="0">
   <test1 id="1">
      <data id="2">
         <entry>
            <string id="3">key1</string>
            <object class="java.lang.String" id="4">value</object>
         </entry>
      </data>
   </test1>

Re: [Simple-support] De-serialization problem -- valid reference not valid?

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

Hi,

This looks strange, also have id= attributes been added manually? I've never seen this error before? Just wondering is there some other manipulation of the resulting XML. For example id="431" before id="438" looks odd. 

Is this easy to reproduce? Would it be possible to write a test case to expose this problem, at least then I could fix the issue from a known reproducable test.

Thanks,
Niall

[Simple-support] De-serialization problem -- valid reference not valid?

[Alan D. <Ala...@zn...>]

Is the following a known bug?  This is using simple-xml-2.0.2 library.  
I recently upgraded so I don't know if this was showing up before.

I have two instantiations of the same class, each one contains a map 
declared as follows:

        @ElementMap protected TreeMap<String, Object> data;

Each instance has a map entry similar to a following:

    data.put("root/source", "original");

When serialized, the overall XML looks good, but when I attempt to read 
it back in, I get an error:

org.simpleframework.xml.graph.CycleException: Invalid reference '439' found
        at 
org.simpleframework.xml.graph.ReadGraph.getReference(ReadGraph.java:158)
        at 
org.simpleframework.xml.graph.ReadGraph.getInstance(ReadGraph.java:126)
        at 
org.simpleframework.xml.graph.ReadGraph.getElement(ReadGraph.java:107)

The XML looks like this:  (I edited out other entries)

        <data id="431">
           <entry>
             <string id="438">root/source</string>
             <object class="java.lang.String" id="439">original</object>
           </entry>
        </data>

Then later in the file:

        <data id="723">
           <entry>
             <string ref="438"/>
             <object class="java.lang.String" ref="439"/>
           </entry>
        </data>

If I manually take out the ref="439" and put in some constant, it 
de-serializes the way you would expect.   My guess is the problem has 
something to do with the the reference is to class Object and not class 
java.lang.String, but the ReadGraph code that throws the exception is 
doing so because it came up with a null out of the reference map.  So 
id="439" never seems to be making into the map.    Is there a fix for this?

Thanks in advance for any help.

[Simple-support] BigInteger in CycleStrategy problem

[Joselito D. M. <joe...@gm...>]

Hello,

Is there a way to turn off CycleStrategy for Elements that are standard java
types?

Let me explain.

Given the class definition:

@Root
public class AClass {

@Element
private BigInteger aBigInteger;
@Element
private BigInteger anotherBigInteger;

//(Setters, getters implied for this code)

}

//In the test code

public class SomeTest {
@Test
public class aTest() {

   BigInteger aBigInteger = new BigInteger("0");

   AClass aClass = new AClass();
   aClass.setABigInteger(aBigInteger);
   aClass.setAnotherBigInteger(aBigInteger);

   Strategy strategy = new CycleStrategy();
   Serializer serializer = new Persister(strategy);
   StringWriter writer = new StringWriter();
   serializer.write(aClass, writer);
   System.out.println(writer.toString());

}
}

The output is:
<AClass id="0">
   <aBigInteger id="1">0</aBigInteger>
   <anotherBigInteger reference="1"/>
</AClass>

What I need is:

<AClass id="0">
   <aBigInteger id="1">0</aBigInteger>
   <anotherBigInteger id="2">0</anotherBigInteger>
</AClass>

That is, I need the second BigInteger property to be treated not as an
element reference because I want standard java data types in my beans to be
treated as different instances even though at runtime, they are pointing to
the same instance.

Could this be added as a future feature maybe?

Thanks,

Joen Moreno

[Simple-support] NullPointerException when attempting to serialize multiply nested generic maps

[Stanislaw O. <sta...@ca...>]

Hello,

I thought I'd let you know that an attempt to serialize an object of class
like this:

    @Root
    private static class ToSerialize
    {
        @ElementMap
        public Map<String, Map<String, String>> map;
    }

results (v2.0.2) in a NullPointerException:

    at org.simpleframework.xml.core.Persister.write(Persister.java:963)

I'm not sure -- is this a bug or some design decision/limitation related to
generics? I'm asking more out of curiosity because I'm happy with a
workaround based on creating a wrapper class that contains a field
corresponding to the "inner" map of the problematic case.

Cheers,

Re: [Simple-support] how to determine where in the xml file/stream anexception is thrown?

[<Nia...@ub...>]

Hi, 

You can do this in a few ways, the simples of which is to use a Strategy
to grab the line number from the NodeMap. For convenience you could put
it in to a thread local then any method invoked in your object can get
the last position reference from the thread local and throw that without
you having to do anything.

There are examples in the test cases, look for tests with Strategy in
them.

If I throw an exception in a "setSomething" method, how can I determine

location)?  Is this info available in a Validate method?

In SAX this is the Locator object and its getLineNumber() and

Re: [Simple-support] XML formatting for attribute lists

[<Nia...@ub...>]

Hi,

Simplest thing to do would be to implement your own writer to scan for new lines, for each new line extracted decide how long the line should be. Then i-- until you find a space, and replace that space with a newline. For example.

LineWriter out = new LineWriter(fileOut);
Persiser persister = new Persister();

persister.write(myObject, out); 

I was intending to do something like this, configurable within the Format object. However, for now you would need to write your own, which should be a simple enough to do.

Re: [Simple-support] Difference between DefaultStrategy and TreeStrategy?

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

Hi,

They do the exact same thing. I did not make DefaultStrategy public for a number of reasons. For one I hate "Default" objects and for another I wanted to have stock strategy types in a single location, without any package cycles. So you can use TreeStrategy to get the exact same functionality as DefaultStrategy.
