public IUnknownServer(CoClassMetaInfo classImpl)

Method Detail

getClassImpl

protected CoClassMetaInfo getClassImpl()

addRef

public ULongInt addRef()

Description copied from interface: IUnknown

Increments the reference count for an interface on an object.

Specified by:

addRef in interface IUnknown

Returns:

new reference count. This value is intended to be used only for test purposes.

addRefAggregated

public ULongInt addRefAggregated()

Calls the addRef method for an aggregate object.

Returns:

count of references for an aggregate object.

release

public ULongInt release()

Description copied from interface: IUnknown

Decrements the reference count for an interface on an object.

Specified by:

release in interface IUnknown

Returns:

new reference count. This value is intended to be used only for test purposes.

doDestroy

protected void doDestroy()

releaseAggregated

public ULongInt releaseAggregated()

Calls release for an aggregate object.

Returns:

count of references for an aggregate object.

queryInterface

public void queryInterface(IID iid,
                           IUnknown pReqInterface)
                    throws ComException

Description copied from interface: IUnknown

Retrieves pointers to the supported interfaces on an object.

Specified by:

queryInterface in interface IUnknown

Parameters:

iid - [in]

pReqInterface - [out]

Throws:

ComException - if the interface is not supported

queryInterfaceAggregated

public void queryInterfaceAggregated(IID iid,
                                     IUnknown pReqInterface)
                              throws ComException

If an aggregate object exists, calls the queryInterface method for it; otherwise calls the queryInterface method for a current object.

Parameters:

iid - IID of a requested interface.

pReqInterface - a requested interface.

Throws:

ComException - when operation fails

doQueryInterface

public boolean doQueryInterface(IID iid,
                                IUnknown intf)

Returns interface by IID.
NOTE: This method does not call addRef() method of this Java COM object.

Parameters:

iid - IID of a requested interface.

intf - a requested interface if true is returned.

Returns:

true if the interface with a specified IID exists, otherwise false.

destroy

protected void destroy()

create

                   IID iid,
                   IUnknown defInterface)
            throws ComException

Creates a co-class and returns its default interface.

Parameters:

outerInterface - an outer interface

iid - IID of the requested interface.

defInterface - output with the default interface for the created co-class (out-only parameter).
