Hi,
Our current code is using drools 5.0.
We have some custom evaluators, which are working fine with 5.0.
example
*Code from Rule:*
Student(code compareCode "426656000, 426979002, 427295004" )
Where Student is a class & "code" is String field in that class. &
compareCode is a custom operator using custom evaluator. as follows.
*code from OP class:*
public static final Operator COMPARE_CODE =
Operator.addOperatorToRegistry( "compareCode",
false );
*Part from Evaluator Definitions class*
private EvaluatorCache evaluators = new EvaluatorCache() {
private static final long serialVersionUID = 100L;
{
addEvaluator( ValueType.STRING_TYPE, D1Operator.COMPARE_CODE,
CodeEvaluator.INSTANCE );
}
};
public static class CodeEvaluator extends BaseEvaluator {
private static final long serialVersionUID = 100L;
public final static Evaluator INSTANCE = new
CodeEvaluator();
public CodeEvaluator() {
super( ValueType.STRING_TYPE,
D1Operator.COMPARE_CODE );
}
public boolean evaluate(InternalWorkingMemory
workingMemory,
final InternalReadAccessor extractor,
final Object object1,
final FieldValue object2) {
final Object value1 = extractor.getValue( workingMemory,
object1 );
//System.out.println("************* in
CodeEqualEvaluator.evaluate");
final Object value2 = object2.getValue();
if ( value1 == null ) {
return value2 == null;
}
//return value1.equals( value2 );
return Utility.checkCode((String)value2, (String)value1);
}
Problem:
Now If I update my Eclipse Drool plugin to 5.2.1 or 5.3 I start getting
error
Evaluator does not support type 'ValueType = 'Object'

Thanks.
