[xstream-user] Is there a way to set the order of Xstream serialization

[Ihar Tsimoshka]

I need to generate XML from java objects on Android. XML nodes must be in
definite sequence.
Due http://xstream.codehaus.org/manual-tweaking-output.html order of XML nodes
match object's fields define. There is no problems when I use java
classes(String, Date...) as fields. But there is problem when I need serialize
my objects as fields.

Here is my code:

    final XStream x = new XStream();

    x.autodetectAnnotations(true);

    SecondEntity secondEntity = new SecondEntity();
    secondEntity.setSecondaryString("Secondary String");
    secondEntity.setSecondaryDate(new Date());

    InnerEntity innerEntity = new InnerEntity();
    innerEntity.setInnerString("Inner String");
    innerEntity.setInnerDate(new Date());

    SomeEntity someEntity = new SomeEntity();
    someEntity.setInnerEntity(innerEntity);
    someEntity.setSecondEntity(secondEntity);
    someEntity.setSomeDate(new Date());
    someEntity.setSomeString("Some string");

    x.toXML(someEntity)

SomeEntity:



    @XStreamAlias("SomeEntity")
    public class SomeEntity {
        @XStreamAlias("innerEntity")
        private InnerEntity innerEntity;
        @XStreamAlias("secondEntity")
        private SecondEntity secondEntity;
        @XStreamAlias("someString")
        private String someString;
        @XStreamAlias("someDate")
        private Date someDate;
    
        public InnerEntity getInnerEntity() {
            return innerEntity;
        }
    
        public void setInnerEntity(InnerEntity innerEntity) {
            this.innerEntity = innerEntity;
        }
    
        public SecondEntity getSecondEntity() {
            return secondEntity;
        }
    
        public void setSecondEntity(SecondEntity secondEntity) {
            this.secondEntity = secondEntity;
        }
    
        public String getSomeString() {
            return someString;
        }
    
        public void setSomeString(String someString) {
            this.someString = someString;
        }
    
        public Date getSomeDate() {
            return someDate;
        }
    
        public void setSomeDate(Date someDate) {
            this.someDate = someDate;
        }
    }

InnerEntity:

    @XStreamAlias("InnerEntity")
    public class InnerEntity {
        @XStreamAlias("innerString")
        private String innerString;
        @XStreamAlias("innerDate")
        private Date innerDate;
    
        public String getInnerString() {
            return innerString;
        }
    
        public void setInnerString(String innerString) {
            this.innerString = innerString;
        }
    
        public Date getInnerDate() {
            return innerDate;
        }
    
        public void setInnerDate(Date innerDate) {
            this.innerDate = innerDate;
        }
    }

SecondEntity:

    @XStreamAlias("SecondEntity")
    public class SecondEntity {
        @XStreamAlias("secondaryString")
        private String secondaryString;
        @XStreamAlias("secondaryDate")
        private Date secondaryDate;

        public String getSecondaryString() {
            return secondaryString;
        }

        public void setSecondaryString(String secondaryString) {
            this.secondaryString = secondaryString;
        }

        public Date getSecondaryDate() {
            return secondaryDate;
        }

        public void setSecondaryDate(Date secondaryDate) {
            this.secondaryDate = secondaryDate;
        } 
    }


I get 

    <SomeEntity>
        <innerEntity>
            <innerDate>2013-02-28 18:04:24.184 UTC</innerDate>
            <innerString>Inner String</innerString>
        </innerEntity>
        <secondEntity>
            <secondaryDate>2013-02-28 18:04:24.183 UTC</secondaryDate>
            <secondaryString>Secondary String</secondaryString>
        </secondEntity>
        <someDate>2013-02-28 18:04:24.184 UTC</someDate>
        <someString>Some string</someString>
    </SomeEntity>

When I need:

    <SomeEntity>
        <innerEntity>
            <innerString>Inner String</innerString>
            <innerDate>2013-02-28 18:04:24.184 UTC</innerDate>
        </innerEntity>
        <secondEntity>
            <secondaryString>Secondary String</secondaryString>
            <secondaryDate>2013-02-28 18:04:24.183 UTC</secondaryDate>
        </secondEntity>
        <someDate>2013-02-28 18:04:24.184 UTC</someDate>
        <someString>Some string</someString>
    </SomeEntity>
