Class IsAEvaluatorDefinition

java.lang.Object

org.drools.traits.core.base.evaluators.IsAEvaluatorDefinition

All Implemented Interfaces:

Externalizable, Serializable, org.kie.api.runtime.rule.EvaluatorDefinition

public class IsAEvaluatorDefinition
extends Object
implements org.drools.core.base.evaluators.EvaluatorDefinition

The implementation of the 'str' evaluator definition.

The str compares two string values.

Lets look at some examples:

$m : Message( routingValue str[startsWith] "R1" )

$m : Message( routingValue str[endsWith] "R2" )

$m : Message( routingValue str[length] 17 )
