SCALA Consulting: Supply Chain and Logistics Consultancy, Note that the result of the test is modulo Scala’s era sure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return.
This member is added by an implicit conversion from Ensuring [A] to Ensuring [ Ensuring [A]] performed by method Ensuring in scala .Predef. Shadowing This implicitly inherited member is shadowed by one or more members in this class. To access this member you can use a type ascription:, Scala provides a set of preconditions functions (assert, assume, require, ensuring). In addition to the actual functionality of dynamically check invariants, these functions are used for documentation and static code analysis. These functions are used to do mainly Desing by Contract (DbC). It’s a software design technique which suggests that software designer should define formal, precise, and verifiable.
12/23/2019 · Scala | Preconditions (assert, assume, require, ensuring) Preconditions refer to some conditions in Scala that need to be fulfilled before going further with any code or program . In Scala, the process of Designing by Contract (DbC), a software designing process gives significance and meaning to Scala preconditions.
