Package org.drools.traits.core.base.evaluators

Class IsAEvaluatorDefinition

  • All Implemented Interfaces:
    java.io.Externalizable, java.io.Serializable, org.drools.compiler.rule.builder.EvaluatorDefinition, org.kie.api.runtime.rule.EvaluatorDefinition
    public class IsAEvaluatorDefinition
extends java.lang.Object
implements org.drools.compiler.rule.builder.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 )
