how do i get target prop_content by using queryAssociated?

[tomcheng76]

Suppose i have the parent Reference, and the associate type, then i can find the "target".
But i can only get a NamedValue which is a string, i am not sure if there is a problem if the content is not plain text.
Can i get the image content by casting it to byte? Or should i get the uuid and use contentService to read the content again (is this slow since it needs two queries ??)?

       Association association = new Association(assocType, "target") ;
       ResultSetRow[] imageRows = repositoryService.queryAssociated(parent, association).getResultSet().getRows();
        // by using getColumns() and search for Constants.PROP_CONTENT, i can get the content in NamedValue format

Hopefully my question is understandable..

okay, end up with this, not sure the performance though

QueryResult queryResult = MyCollection.getAssociatedChild(currentRef, ICMConstants.ASSOC_IMAGES);
ResultSetRow[] imageRows = queryResult.getResultSet().getRows();
for (ResultSetRow imageRow : imageRows) {
ResultSetRowNode imageNode = imageRow.getNode();
String imageNodeId = imageNode.getId();
               
Reference imageRef = new Reference(dsICM.getStore(), imageNodeId, null);
Predicate imagePredicate = new Predicate(new Reference[]{imageRef}, dsICM.getStore(), null);
Content[] readResult = dsICM.getContentService().read(imagePredicate, ICMConstants.PROP_CONTENT);
Content imageContent = readResult[0];
InputStream imageIn = ContentUtils.getContentAsInputStream(imageContent);
byte[] content = IOUtils.toByteArray(imageIn);
}

reading testcase is much better than sdk example, they are more solid 🙂
