| [higgins-dev] IdAS interface questions |
|
Hi, Jim.
We have some questions about IdAS interfaces. Now in order to get full information of Entity we need many IdAS calls, such as getAttributes(), getValues(), getData() etc. And the more actual data (more Attributes with values present) then more calls need to be done respectively. For example to get the m-card with claims we need get many attributes for claim types, get their values, simple as well as complex, getting their attributes and so on. In common case to get the full Entity we need do something like this: IEntity entity = context.getEntity(entityID); Iterator itAttributes =
entity.getAttributes();
while
(itAttributes.hasNext()) {
IAttribute
attr = (IAttribute) itAttributes.next();
processAttribute(attr);
}
public void processAttribute(IAttribute
attr) {
Iterator
itValues = attr.getValues();
while (itValues.hasNext()) {
IAttributeValue val = (IAttributeValue)
itValues.next();
if (val.isSimple())
{
Object data = ""
val).getData();
doSomethingWith(data);
}
else {
Iterator itAttr = ((IComplexAttrValue)
val).getAttributes();
while (itAttr.hasNext())
{
processAttribute((IAttribute)itAttr.next());
}
}
}
}
Is it possible to reduce number of IdAS calls to get the full Entity data? May be it would be good to change interfaces so that it will no need in cycles and big number of separate calls...Probably it is possible to change IComplexAttrValue and IEntity interfaces, method getAttributes() so that we could be able to narrow the attribute set and filter them by value to get only information that we need, and get all of the attributes with values all in one at a time.
