RapidIdentity Product Guide: New UI

Java Implementation

  • Familiarity with language

  • Better type checking

  • Better tools and IDE support

  • Easier debugging

  • Existing code

  • Calculation intensive algorithms

  • Records and Objects

    • Records and to a lesser extent Objects are some of the most used data structures in RapidIdentity Connect, but unfortunately, they are designed to primarily be used from ECMAScript and not easily usable from Java. Your best bet is to create and pass instance-specific Java classes after copying the necessary field/property values from the Record/object.

  • XML

    • An E4X XML object is not particularly useful in Java, but fortunately, Rhino's default E4X implementation uses Java DOM underneath. This allows you to declare a parameter in Java as org.w3c.dom.Node and when calling from ECMAScript use an underlying method that extracts the DOM node.

    • Note however that the DOM Node extracted from the E4X XML object should probably be considered strictly read-only.

  • undefined

    • Rhino passes the special value undefined to Java as an instance of the underlying class the Rhino uses to represent that value. This is not particularly useful in Java, so given that an adapter is supposed to treat null and undefined as if they were the same, the best way to deal with undefined is to make sure the ECMAScript wrapper checks for undefined and changes it to null before passing to Java.
