getChildList
The
getChildList()
method returns the
Iterator
for the child objects of the
DataDescription
.
public Iterator getChildList() throws MetadataException
{
return (this.getMetadataObject().getChildren(null)).getObjectIterator();
}
WBIInboundServiceDescriptionImpl samples:
WBIInboundServiceDescriptionImpl
represents the object that populates function
descriptions for inbound service descriptions.
Implement the method shown in the section below.
setFunctionDescriptions
The
setFunctionDescriptions()
method populates function descriptions based on
objects 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 (int i = 0; i < selectedObjects.length; i++) {
WBIMetadataImportConfigurationImpl spec =
(WBIMetadataImportConfigurationImpl) selectedObjects[i];
WBIInboundFunctionDescriptionImpl functionDescription;
TwineBallMetadataObject metadataObj =
(TwineBallMetadataObject) spec.getMetadataObject();
for (int j = 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);
functionDescriptions.add(functionDescription);
}
}
