i want to parse a project in which some classes have inner classes.how can i extract inner classes name other information using eclips JDT?
You can traverse through the Compilation unit of the Java class and visit the TypeDeclaration AST node. The below code can then be used to check if it is not a top-level class, i.e an inner class.
public boolean visit(TypeDeclaration typeDeclarationStatement) {
if (!typeDeclarationStatement.isPackageMemberTypeDeclaration()) {
System.out.println(typeDeclarationStatement.getName());
// Get more details from the type declaration.
}
return true;
}
For getting anonymous inner classes use the below code too:
public boolean visit(AnonymousClassDeclaration anonyomousClassDeclaration) {
System.out.println(anonyomousClassDeclaration.toString());
return true;
}
Details on Class traversal using JDT can be found from below link:
Eclipse create CompilationUnit from .java file
If you have an IType instance (type) then you can query the inner classes by
type.getTypes();
which will give you an array of the immediate member types declared by this type.

I was working on COM/ATL. I need to use a class object as return value so that it can be used in managed code. I am able to define structure in idl file and also able to use it as return parameter when creating methods.
Below is the partial idl file implementation:
import "oaidl.idl";
import "ocidl.idl";
//Structure for message mapping of activation and deactivation
//Structures are working properly
[uuid(E2240D8B-EB97-4ACD-AC96-21F2EAFFE100)]
struct tagActivationManaged
{
WORD wMsgId;
WORD wStatus;
WORD wClient;
WORD wClientId;
};
//same manner if creating class it throws error.
[uuid(2ED2E59C-9362-46b2-80D8-471AD69BA5D5)]
class AuthenticationMessage
{
public:
Word message;
}
do I need to change any settings in MIDL.
NB: I am new to COM programming.
You just can't do that - there're no C++ flavor classes in IDL. If you want to return an object of some class from a function you have to declare an interface and possibly a coclass (the latter may not be required depending on your sitiation) and make the function return that interface.
To start: This is also for REST deserialiaztion, so a custom XmlSerializer is out of the question.
I have a hjierarchy of classes that need to be serializable and deserializable from an "Envelope". It has an arrayelement named "Items" that can contain subclasses of the abstract "Item".
[XmlArray("Items")]
public Item [] Items { get; set; }
Now I need to add XmlArrayItem, but the number is not "fixed". We use so far reflection to find all subclasses with a KnownTypeProvider so it is easy to extend the assembly with new subtypes. I dont really want to hardcode all items here.
The class is defined accordingly:
[XmlRoot]
[KnownType("GetKnownTypes")]
public class Envelope {
but it does not help.
Changing Items to:
[XmlArray("Items")]
[XmlArrayItem(typeof(Item))]
public Item [] Items { get; set; }
results in:
{"The type
xxx.Adjustment
was not expected. Use the XmlInclude
or SoapInclude attribute to specify
types that are not known statically."}
when tyrying to serialize.
Anyone an idea how I can use XmlInclude to point to a known type provider?
The KnownTypesAttribute does not work for XmlSerializer. It's only used by a DataContractSerializer. I'm quite sure that you can exchange the serializer in WCF, because I have done that for the DataContractSerializer. But if that's not an option, you have to implement IXmlSerializable yourself and handle type lookup there.
Before disqualifying this solution: You just have to implement IXmlSerializable just for a special class which replaces Item[]. Everything else can be handled by the default serializer.
According to: http://social.msdn.microsoft.com/Forums/en-US/asmxandxml/thread/83181d16-a048-44e5-b675-a0e8ef82f5b7/
you can use different XmlSerializer constructor:
new XmlSerializer(typeof(Base), new Type[] { typeof(Derived1), ..});
Instead of enumerating all derived classes in the base definition like this:
[System.Xml.Serialization.XmlInclude(typeof(Derived1))]
[System.Xml.Serialization.XmlInclude(typeof(Derived2))]
[System.Xml.Serialization.XmlInclude(typeof(DerivedN))]
I think you should be able to use your KnownTypeProvider to fill the array in the XmlSerializer's constructor.
I am using a sping ws endpoint with jaxb marshalling/unmarshalling to proudce a list of Organisation objects (our local type). The endpoint is SOAP 1.1, no parameters supplied on the request message.
I understand JAXB doesn't handle lists very well, so I use a wrapper class.
#XmlRootElement(name="orgResponse", namespace=....)
public class OrganisationListWrapper {
private ArrayList<Organisation> organisationList;
public getOrganisationList() {
return organisationList;
}
public setOrganisationList(ArrayList<Organisation> organisationList) {
this.organisationList = organisationList;
}
}
The endpoint....
#PayloadRoot(localPart=.... namespace=....)
#ResponsePayload
public OrganisationListWrapper getOrganisations() {
OrganisationListWrapper wrapper = new OrganisationListWrapper();
wrapper.setOrganisationList(.... call service layer get list ....);
return wrapper;
}
This works fine and I get a SOAP payload with
<orgResponse>
<organisationList>
... contents of organisation 1
</organisationList>
<organisationList>
... comtents of organisation 2
</organisationList>
.... etc ....
</orgResponse>
The Organisation class is not JAXB annotated. It is part of a large list of pre-existing classes that are being exposed through web services for the first time. Trying to get by without going in and annotating them all by hand.
I was able to override the name OrganisationWrapper with orgResponse in the XmlRootElement annotation. I would like to override the organisationList name in the child element with organisation but haven't been able to find an annotation that does this.
I can replace the array list name with organisation and it will work fine, but our coding standard here required us to put List on the end of our list names. I would like to try and stick to that. I have tried XmlElement, but that produced a jaxb exception.
Any suggestions would be appreciated.
Because JAXB default the access type to PUBLIC_MEMBER, make sure you annotate the property (getter) and not the field:
#XmlElement(name="organisation")
public getOrganisationList() {
return organisationList;
}
If you want to annotate the field then add the following annotation to your class:
#XmlAccessorType(XmlAccessType.FIELD)
I am running into a problem when trying to implicitly convert one of my dynamic types. There are two assemblies with definitions similar to the following:
Configuration.dll:
public class ConfigurationValue : DynamicObject
{
public ConfigurationValue(string val)
{
//...
}
//...
public static implicit operator string(ConfigurationValue val)
{
return val.ToString();
}
}
There is another class in this dll called Configuration with a member variable called Instance (to make the class singleton). This variable holds the ConfigurationValue instances in a dictionary and is of type dynamic. This allows me to do this following:
Server.dll:
//...
if (Configuration.Instance.SecurityLevel != "Insecure")
{
//...
}
Assuming that SecurityLevel is in the dictionary.
This if statement appears verbatim in my code and always fails with the following error:
{"Operator '!=' cannot be applied to operands of type 'System.Dynamic.DynamicObject' and 'string'"}
Previously, when these two classes were in the same assembly, this code worked fine. Can anyone tell me what I'm doing wrong here?
Thanks,
Max
Solved the problem, a little embarrassing actually, I forgot to change the container class for ConfigurationValue (e.g. the type of Configuration.Instance) from internal to public when I moved it to the new assembly, so of course the type couldn't be resolved and the implicit conversion was not found
Try
var SecurityLevel = new ConfigurationValue("Insecure");
I am looking for help to achieve the following
The Diagram represents a car, users can add engine and colour
when I view the XML it looks like this:
<Car>
<Engine>BigEngine</Engine>
<Colour>Pink</Colour>
</Car>
What I would like to do is to wrap the car inside 'vehicle', i.e
<Vehicle>
<Car>
<Engine>BigEngine</Engine>
<Colour>Pink</Colour>
</Car>
</Vehicle>
I am not sure of the best way to achieve this. I want the model explorer and the generated XML to be wrapped in 'vehicle' but for all other intents and purposes the user is working with a car only
Info: Visual Studio 2010, C# and DSL SDK for 2010
I would try two different approaches:
1st: override DSL Package class DocData
In DocData.cs file and override method
protected override void OnDocumentSaved(System.EventArgs e)
and then I would create the wrapper
afterwards I'd override in DocData.cs
protected override void OnDocumentLoading(System.EventArgs e)
and before calling the base method base.OnDocumentLoading(e); i would delete from the file.
2nd: Under DSL Explorer go to XML Serialization Behaviour and set Car Domain Class "Is Custom = true".
This solution is not straightforward but it's not as complicated as it seems at the first place. You'll must define every single method but for each custom method you can call a DSL generated method called "DefaulMethod" which has the default DSL serializer behaviour.
I am currently using VS 2005, so some things might have changed...
I have fixed this by the following. I am double deriving the Car class and in the Car serializer I am doing this:
Writing the extra elements:
public partial class CarSerializer : CarSerializerBase
{
public override void Write(SerializationContext serializationContext, ModelElement element, XmlWriter writer, RootElementSettings rootElementSettings)
{
// Adds the Model and LobSystem root elements to match that required by the SharePoint BCS
writer.WriteStartElement("Garage");
writer.WriteStartElement("Cars");
base.Write(serializationContext, element, writer, rootElementSettings);
writer.WriteEndElement();
writer.WriteEndElement();
}
}
To be able to read this back in I am overriding the Car LoadModel method in the SerializationHelper and where it is getting the reader I am reading the elements until I get to Car.
....
XmlReader reader = XmlReader.Create(fileStream, settings);
reader.MoveToContent();
while (!reader.EOF && !reader.Name.Equals("Car"))
{
reader.Read();
}
reader = reader.ReadSubtree();
// using (global::System.Xml.XmlReader reader = global::System.Xml.XmlReader.Create(fileStream, settings))
using (reader)
{
....
