[rules-users] MultiValueRestriction

[droolster]

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
