[rules-users] MultiValueRestriction

Hello, I saw the following in the "Design Patterns for PRS system" pdf and could not understand the difference between the two statements (they look the same to me). Please can the community clarify what the difference is: A multiple choice could be written using the same syntactic form, e.g., Type( strField == "Huey" || == "Dewey" || == "Louie" ) but if you are testing for equality, the MultiValueRestriction is to be preferred, so that the preceding pattern is better written as Type( strField in ( "Huey", "Dewey", "Louie" ) ) Thank you, Iftikhar -- View this message in context: http://drools.46999.n3.nabble.com/MultiValueRestriction-tp4024384.html Sent from the Drools: User forum mailing list archive at Nabble.com.
