java - JAXB not creating member variables and getters and setters -


i trying generate java classes form xsd schema , using jaxb. part when run process generate classes works. there few classes member variable, getters , , setters not generated. here have

file ns2.xsd

<xs:element name="observation" type="ns2:observationtype" substitutiongroup="ns1:_metadata"/> <xs:complextype name="observationtype" mixed="true">     <xs:complexcontent mixed="true">         <xs:extension base="ns1:abstracttype">             <xs:sequence>                     <xs:element ref="ns2:identifier"/>              </xs:sequence>         </xs:extension>     </xs:complexcontent> </xs:complextype>

file ns3.xsd

<xs:element name="observation" type="ns3:observationtype" substitutiongroup="ns2:observation"/> <xs:complextype name="observationtype" mixed="true">     <xs:annotation>         <xs:documentation>this extends ns2:observationtype </xs:documentation>     </xs:annotation>     <xs:complexcontent mixed="true">         <xs:extension base="ns2:observationtype">             <xs:sequence>                 <xs:element ref="ns3:deliveryinfo" minoccurs="0"/>             </xs:sequence>         </xs:extension>     </xs:complexcontent> </xs:complextype>

this creates empty class 

package mypackage.ns3;  import javax.xml.bind.annotation.xmlaccesstype; import javax.xml.bind.annotation.xmlaccessortype; import javax.xml.bind.annotation.xmltype;   /**  * extends ns2:observationtype   *   * <p>java class observationtype complex type.  *   * <p>the following schema fragment specifies expected content contained within class.  *   * <pre>  * &lt;complextype name="observationtype">  *   &lt;complexcontent>  *     &lt;extension base="{http://earth.esa.int/ns2}observationtype">  *       &lt;sequence>  *         &lt;element ref="{http://earth.esa.int/ns3}deliveryinfo" minoccurs="0"/>  *       &lt;/sequence>  *     &lt;/extension>  *   &lt;/complexcontent>  * &lt;/complextype>  * </pre>  *   *   */ @xmlaccessortype(xmlaccesstype.field) @xmltype(name = "observationtype") public class observationtype     extends mypackage.ns2.observationtype {   }

my question why not creating required member variable , setters , getters? there wrong schema or there limitation on jaxb create missing information form complex types use extensions different files? thank in advance. or comments appreciated.

what makes use case odd have inheritance in xml schema between 2 types mixed content. think there xjc (and possibly spec) bug here, , suggested puce should enter bug @ following link:

xml schema

schema.xsd

here simpler xml schema reproduces same issue:

<?xml version="1.0" encoding="utf-8"?> <schema      xmlns="http://www.w3.org/2001/xmlschema"      targetnamespace="http://www.example.org/schema"      xmlns:tns="http://www.example.org/schema"      elementformdefault="qualified">      <complextype name="b" mixed="true">                  <sequence>                    <element ref="tns:bb"/>                 </sequence>     </complextype>       <complextype name="c">         <complexcontent mixed="true">             <extension base="tns:b">                 <sequence>                    <element ref="tns:cc"/>                 </sequence>             </extension>         </complexcontent>     </complextype>      <element name="bb" type="string"/>      <element name="cc" type="string"/>  </schema>

incorrect java model

b

the class generated b type fine.

@xmlaccessortype(xmlaccesstype.field) @xmltype(name = "b", proporder = {"content"}) @xmlseealso({c.class}) public class b {      @xmlelementref(name = "bb", namespace = "http://www.example.org/schema", type = jaxbelement.class)     @xmlmixed     protected list<serializable> content;      public list<serializable> getcontent() {         if (content == null) {             content = new arraylist<serializable>();         }         return this.content;     }  }

c

the class generated c type wrong, question should be?

@xmlaccessortype(xmlaccesstype.field) @xmltype(name = "c") public class c extends b {   }

better java model? - option #1

you add property c class. question comes down of mixed text goes on property inherited b , goes in property defined on c.

@xmlaccessortype(xmlaccesstype.field) @xmltype(name = "c") public class c     extends b {      @xmlelementref(name = "cc", namespace = "http://www.example.org/schema", type = jaxbelement.class)     @xmlmixed     protected list<serializable> content2;  }

better java model? - option #2

you extend property on b aware of element reference c type. allow handle xml correctly b , c types allows documents weren't valid against xml schema.

@xmlaccessortype(xmlaccesstype.field) @xmltype(name = "b", proporder = {"content"}) @xmlseealso({c.class}) public class b {      @xmlelementrefs({         @xmlelementref(name = "bb", namespace = "http://www.example.org/schema", type = jaxbelement.class),         @xmlelementref(name = "cc", namespace = "http://www.example.org/schema", type = jaxbelement.class)     })     @xmlmixed     protected list<serializable> content;      public list<serializable> getcontent() {         if (content == null) {             content = new arraylist<serializable>();         }         return this.content;     }  }

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)...
