alma.demo.XmlComponentImpl

Class XmlComponentImpl

java.lang.Object

alma.acs.component.ComponentImplBase

alma.demo.XmlComponentImpl.XmlComponentImpl

All Implemented Interfaces:

ComponentLifecycle

public class XmlComponentImpl
extends ComponentImplBase

A test component that implements the XmlComponentImpl interface from demo.idl. The implemented functional interface, XmlComponentJ, uses Castor binding classes, where the IDL (and XmlComponentOperations) use serialized XML strings inside the XmlEntityStruct.

In addition to methods for testing the transparent-xml feature, there is the method sayHello, which is meant to internally contact another component (HelloDemo).

Method Detail

initialize

public void initialize(ContainerServices contServices)
                throws ComponentLifecycleException

Description copied from class: ComponentImplBase

Subclass must call super.initialize(containerServices) unless it overrides as well all other methods which access the member vars of this class.

Specified by:

initialize in interface ComponentLifecycle

Overrides:

initialize in class ComponentImplBase

Parameters:

contServices - callback object for services provided by the container

Throws:

ComponentLifecycleException

See Also:

ComponentLifecycle.initialize(ContainerServices)

dumbMethod

public int dumbMethod(java.lang.String somevalue)

from IDL: long dumbMethod(in string somevalue);

See Also:

alma.demo.XmlComponentJ#dumbMethod(java.lang.String)

createObsProposal

public ObsProposal createObsProposal()

from IDL: ObsProposal createObsProposal();

See Also:

alma.demo.XmlComponentJ#createObsProposal()

getBestSchedBlock

public SchedBlock getBestSchedBlock()

See Also:

alma.demo.XmlComponentJ#getBestSchedBlock()

getAllSchedBlocks

public SchedBlock[] getAllSchedBlocks()

from IDL: SchedBlockSeq getAllSchedBlocks();

See Also:

alma.demo.XmlComponentJ#getAllSchedBlocks()

addNewSchedBlocks

public void addNewSchedBlocks(SchedBlock[] newSchedBlocks)

See Also:

alma.demo.XmlComponentJ#addNewSchedBlocks(alma.xmljbind.test.schedblock.SchedBlock[])

xmlInOutMethod

public void xmlInOutMethod(ObsProposal opsPropIn,
                           SchedBlockHolder schedBlockOut)

from IDL: void xmlInOutMethod(in ObsProposal opsPropIn, out SchedBlock schedBlockOut);

See Also:

alma.demo.XmlComponentJ#xmlInOutMethod(alma.xmljbind.test.obsproposal.ObsProposal, alma.demo.SchedBlockHolder)

getEntireTreeInAStruct

public ObsProjectTreeJ getEntireTreeInAStruct()

Returns the ObsProposal from createObsProposal() and the SchedBlocks from getAllSchedBlocks() together in a struct. Illustrates and tests the usage of xml entity classes inside IDL structs, or rather their usage as Java class members from an implementation point of view.

See Also:

alma.demo.XmlComponentJ#getEntireTreeInAStruct()

sayHello

public java.lang.String sayHello()

See Also:

alma.demo.XmlComponentJ#sayHello()

exceptionMethod

public void exceptionMethod()
                     throws XmlComponentErrorEx

At the CORBA interface level, we must use the CORBA-exceptions.

Throws:

XmlComponentErrorEx - with an alma.ACSErr.ErrorTrace inside; the ErrorTrace will contain a NullPointerException.

internalExceptionMethod

public void internalExceptionMethod()
                             throws AcsJXmlComponentErrorEx

Inside the Java implementation, we can throw around native Java exceptions generated from the error specifications.

Throws:

AcsJXmlComponentErrorEx - because that one is easier to work with than the corresponding XmlComponentErrorEx, and this method is not part of the (CORBA) component interface.

getOffshoot

public XmlOffshootJ getOffshoot()

deactivateOffshoot
