Hi all,
Recently, I've found something wrong in CEP query output attribute executors.
In DivideExpressionExecutorLong.java, the execute method was written as
---------------------------------------------------------
public Object execute(AtomicEvent event) {
return ((Number) leftExpressionExecutor.execute(event)).doubleValue() /
((Number) rightExpressionExecutor.execute(event)).doubleValue();
}
---------------------------------------------------------
hence, the result of the output Object is of type Double, but this particular
executor requires output type Long. All executors under the divide category
suffers from this issue. The consequence is to cause a java cast exception
when the wrong type of attribute occurs in the output stream, and the attribute
is used in the followed queries.
Hope this will be fixed, thanks.
