[aspectj-users] Quick Question
|
How would I fashion a point cut that matched a method invocation only
if it had not already been applied to an overridden form of that
method in a superclass? For instance in one project I have:
public class SimpleQuery{
public void appendConstraints(){
..add default constraints..
}
}
public interface SuppressableQuery{
...some stuff relevant to suppression...
}
public aspect SuppressableQueryAspect{
void around(SuppressableQuery query) : execution(protected void
SimpleQuery.appendConstraints()) && this(query) {
/* Not really important what this does, just when it is applied */
if(query.getSuppressed() != null){
query.addClause(
(query.getSuppressed() ? "" : "NOT ") + "EXISTS (SELECT
suppression.partitionId " +
"FROM " + query.getSuppressionType().getName() +
" suppression WHERE suppression.partitionId IN
(:suppressionOrder) " +
"AND suppression.entity = " + query.getSuppressedEntityField() +
")");
query.addParameter("suppressionOrder", query.getSuppressionOrder());
}
proceed(query);
}
}
Then in another project with a jar containing the jar from the first
project on the aspect path:
public class ProfileQuery extends SimpleQuery<Profile> implements
PartitionedQuery<Profile>, SuppressableQuery<Profile> {
@Override
protected void appendConstraints() {
super.appendConstraints();
if(onetOccupationStub != null){
addClause(alias("delegate") + " = :onetOccupationStub");
addParameter("onetOccupationStub", onetOccupationStub);
}
}
}
What I'm seeing is that the clause is added to the query twice, when
I only want it to match one invocation of appendConstraints, in this
case the one in ProfileQuery. Can that be done?
