inheritance - EclipseLink MOXy: Override rules of binding files -


i would, in scenario below, binding of java-type name="subclass" applied set text field on superclass. not. there problem overriding bindingsa.xml? according overriding rules documentation:

if same java-type occurs in multiple files, values set in later file, override values previous file

what need make work?

input:

<?xml version="1.0" encoding="utf-8"?> <a text="a text">b text</a>

bindings a:

<?xml version="1.0"?> <xml-bindings  xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"  package-name="test">   <java-types>            <java-type name="superclass">     <xml-root-element name="a"/>     <java-attributes>         <xml-element java-attribute="text" xml-path="@text" />     </java-attributes>   </java-type>  </java-types>  </xml-bindings>

bindings b:

<?xml version="1.0"?> <xml-bindings  xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"  package-name="test">  <java-types>           <java-type name="superclass" xml-transient="true"></java-type>   <java-type name="subclass">     <xml-root-element name="a"/>     <java-attributes>         <xml-element java-attribute="text" xml-path="text()" />     </java-attributes>   </java-type> </java-types>  </xml-bindings>

classes:

public class superclass {   private string text;   public string gettext() {     return text;  }   public void settext(string text) {     this.text = text;  } }  public class subclass extends superclass { }

demo:

map<string, object> jaxbcontextproperties = new hashmap<string, object>(1); list<string> bindings = new linkedlist<string>(); bindings.add("bindingsa.xml"); bindings.add("bindingsb.xml"); jaxbcontextproperties.put(jaxbcontextproperties.oxm_metadata_source, bindings); jaxbcontext jaxbcontext = jaxbcontextfactory.createcontext(new class[] {superclass.class}, jaxbcontextproperties); unmarshaller unmarshaller = jaxbcontext.createunmarshaller(); superclass superclass = (superclass)unmarshaller.unmarshal(new file("input.xml")); system.out.println(superclass.gettext());

output:

[el warning]: 2013-07-31 16:08:07.771--ignoring attribute [text] on class [subclass] no property generated it. text

it's bit odd map text property differently on super , sub classes. if want do, below way accomplish this.

java model

superclass

package forum17982654;  public class superclass {      private string text;      public string gettext() {         return text;     }      public void settext(string text) {         this.text = text;     }  }

subclass

we override accessor methods super class. trick moxy thinking subclass has own property text.

package forum17982654;  public class subclass extends superclass {      @override     public string gettext() {         return super.gettext();     }      @override     public void settext(string text) {         super.settext(text);     }   }

metadata

bindings.xml

in mapping document tell moxy real super class of subclass java.lang.object. 

<?xml version="1.0"?> <xml-bindings     xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"     package-name="forum17982654">     <java-types>         <java-type name="superclass">             <xml-root-element/>             <java-attributes>                 <xml-attribute java-attribute="text"/>             </java-attributes>         </java-type>         <java-type name="subclass" super-type="java.lang.object">             <xml-root-element/>             <java-attributes>                 <xml-value java-attribute="text"/>             </java-attributes>         </java-type>     </java-types> </xml-bindings>

demo code

below demo code can run prove works:

demo

package forum17982654;  import java.io.stringreader; import java.util.*; import javax.xml.bind.*; import org.eclipse.persistence.jaxb.jaxbcontextfactory; import org.eclipse.persistence.jaxb.jaxbcontextproperties;  public class demo {      public static void main(string[] args) throws exception {         map<string, object> jaxbcontextproperties = new hashmap<string, object>(1);         jaxbcontextproperties.put(jaxbcontextproperties.oxm_metadata_source, "bindings.xml");         jaxbcontext jaxbcontext = jaxbcontextfactory.createcontext(new class[] {superclass.class}, jaxbcontextproperties);         unmarshaller unmarshaller = jaxbcontext.createunmarshaller();          stringreader superclassxml = new stringreader("<superclass text='hello super class'/>");         superclass superclass = (superclass) unmarshaller.unmarshal(superclassxml);         system.out.println(superclass.gettext());          stringreader subclassxml = new stringreader("<subclass>hello sub class</subclass>");         subclass subclass = (subclass) unmarshaller.unmarshal(subclassxml);         system.out.println(subclass.gettext());     }  }

output

hello super class hello sub class

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
