getChildListThe getChildList() method returns the Iterator for the child objects of theDataDescription.

public Iterator getChildList() throws MetadataException

{

return (this.getMetadataObject().getChildren(null)).getObjectIterator();

}

WBIInboundServiceDescriptionImpl samples:WBIInboundServiceDescriptionImpl represents the object that populates functiondescriptions for inbound service descriptions.Implement the method shown in the section below.setFunctionDescriptionsThe setFunctionDescriptions() method populates function descriptions based onobjects and properties selected in MetadataSelection .

public void setFunctionDescriptions(MetadataSelection selection)

throws MetadataException {

MetadataImportConfiguration[] selectedObjects = selection.getSelection();

PropertyGroup selectionProperties =

((WBIMetadataSelectionImpl) selection).getAppliedSelectionProperties();

WBIMultiValuedPropertyImpl operationsProperty =

(WBIMultiValuedPropertyImpl) selectionProperties.getProperty("Operations");

String[] operations = operationsProperty.getValuesAsStrings();

ArrayList functionDescriptions = new ArrayList();

String location = TwineBallConfigurationProperties.getLocation

(selectionProperties);

// iterate through the objects.

for(inti=0;i<selectedObjects.length; i++) {

WBIMetadataImportConfigurationImpl spec =

(WBIMetadataImportConfigurationImpl) selectedObjects[i];

WBIInboundFunctionDescriptionImpl functionDescription;

TwineBallMetadataObject metadataObj =

(TwineBallMetadataObject) spec.getMetadataObject();

for(intj=0;j<operations.length; j++) {

String operation = operations[j];

functionDescription = new WBIInboundFunctionDescriptionImpl();

char firstCharacter = operation.charAt(0);

//convention for displaying the outbound function.

functionDescription.setName

("emit" + Character.toUpperCase(firstCharacter) +

operation.substring(1).toLowerCase() + "AfterImage" +

StringCaseChanger.toCamelCase(metadataObj.getDisplayName()));

functionDescription.setEISFunctionName(functionDescription.getName());

functionDescription.setImportConfiguration(spec);

TwineBallDataDescription dataDescription = new TwineBallDataDescription();

dataDescription.setMetadataObject(metadataObj);

dataDescription.setName(getNameSpace(),

StringCaseChanger.toCamelCase(metadataObj.getDisplayName()));

dataDescription.populateSchemaDefinitions();

dataDescription.setRelativePath(location);

dataDescription.setName(getNameSpace() + "/" +

metadataObj.getBOName().toLowerCase() +

"bg", metadataObj.getBOName() + "BG");

functionDescription.setInputDataDescription(dataDescription);
