2) Validate the query for my plugins property only before proceeding in processProertyConstrain(..
4) Add additional property pair in and append VM in iteration to result set with new properties and resourceObject reference of that VM
Please have a look at below code and please let me know if i am doing any mistake here or is there any other way to return a new custom column value for VM list view.
private List<ResultItem> processPropertyConstraint(PropertyConstraint pc,
PropertySpec[] propertySpecs) {
assert (pc.comparator == Comparator.TEXTUALLY_MATCHES);
String comparableValue = pc.comparableValue.toString().toLowerCase();
List<ResultItem> items = new ArrayList<ResultItem>();
Boolean myPlugin_Query = validateVMWareViewQueries(propertySpecs);
if(pc.targetType.equals(Constants.VMWARE_VIRTUALMACHINE) && myPlugin_Query){
items=getVirtualMachinesFromVCAndAppendMyCustomPropertyinResultSet(propertySpecs);
return items;
}
}
//Method to validate whether it is valid query for custom column property for my plugin
private Boolean validateVMWareViewQueries(PropertySpec[] propertySpecs) {
Boolean myPlugin_Query=false;
if(propertySpecs.length>0){
List<String> propNameinPropSpec=Arrays.asList(propertySpecs[0].propertyNames);
if(!propNameinPropSpec.isEmpty() && propNameinPropSpec.contains("VM_MYPLUGIN_DATA")){
myPlugin_Query=true;
}
else{
myPlugin_Query=false;
}
}
return myPlugin_Query;
}
//Method to retun list of Virtual machine as ResultItem with additional property-value pair
private List<ResultItem> getVirtualMachinesFromVCAndAppendMyCustomPropertyinResultSet(PropertySpec[] propertySpecs) {
// create QuerySpec
List<ResultItem> reultItem = new ArrayList<ResultItem>();
QuerySpec qs = new QuerySpec();
qs.resourceSpec = new ResourceSpec();
qs.resourceSpec.constraint = new Constraint();
// HostSystem is the targetType
qs.resourceSpec.constraint.targetType = "VirtualMachine";
// request the name property
PropertySpec pSpec = new PropertySpec();
pSpec.propertyNames = new String[]{"name"};
qs.resourceSpec.propertySpecs = propertySpecs;
qs.resultSpec = new ResultSpec();
// qs.resultSpec.maxResultCount = new Integer(maxResultCount);
// use default ordering
qs.resultSpec.order = new OrderingCriteria();
qs.resultSpec.order.orderingProperties = new OrderingPropertySpec[0];
// get data from DataService
RequestSpec requestSpec = new RequestSpec();
requestSpec.querySpec = new QuerySpec[]{qs};
//Here Fetching the ALL VM Objects from webclient service
Response response = _dataService.getData(requestSpec);
ResultItem[] items = response.resultSet[0].items;
if (items!= null) {
for(ResultItem vmObjResultItems:items)
{
//Here we processed each VM and return specific property for each VM(Based on My plugin logic) add it as
// pv.propertyName = "VM_MYPLUGIN_DATA";
//pv.value = "VM_MYPLUGIN_DATA";
vmObjResultItems.resourceObject = toURI(vmObjResultItems.resourceObject);
ArrayList<PropertyValue> propValArr = new ArrayList<PropertyValue>(1);

pv.resourceObject = (vmObjResultItems.resourceObject);
pv.propertyName = "VM_MYPLUGIN_DATA";
pv.value = "VM_MYPLUGIN_DATA";
propValArr.add(pv);
vmObjResultItems.properties = propValArr.toArray(new PropertyValue[0]);
reultItem.add(vmObjResultItems);
}
}
return reultItem;
}
