Like lists and tuples, option values are simple constructs frequently used as workhorses in F# coding. An option is simply either a value Some(v) or the absence of a value None. For example, options are useful for returning the value of a search where you may or may not have a result. You see in the section Defining Discriminated Unions that the option type is defined in the F# library as follows: type 'T option = | None | Some of 'T The following is a data structure that uses options to represent the (optional) parents of some wellknown characters: > let people = [ ("Adam", None); ("Eve" , None); ("Cain", Some("Adam","Eve")); ("Abel", Some("Adam","Eve")) ];; val people : (string * (string *string) option) list Pattern matching is frequently used to examine option values: > let showParents (name,parents) = match parents with | Some(dad,mum) -> printfn "%s has father %s, mother %s" name dad mum | None -> printfn "%s has no parents!" name;; val showParents : (string * (string * string) option) -> unit > showParents ("Adam",None);; Adam has no parents val it : unit = () The F# library also includes a module Option that contains useful functions for programming with options. Table 3-10 shows some of these. Although it s easy to code them by hand using pattern matching, it can also be useful to learn and rely on the standard definitions. Table 3-10. Some Sample Functions in the Option Module

How It Works You added an UPDATE statement and changed the name of the original query string variable from sql to upd in order to clearly distinguish it from this statement:

The GenericPortlet class implements the PortletConfig interface, so any subclass of GenericPortlet may just call getPortletContext() on itself. If your portlet directly implements the Portlet interface, your init(PortletConfig config) method must retain a reference to the PortletConfig object.

Negative packages are those you use to remove (rather than add) applications. The easiest way to remove an application is with an uninstaller that the application vendor provides. If you don t have that (or if it doesn t work, which happens), more than likely you ll want to use a negative package. You can also use it at install time to remove any applications bundled with the operating system if they were in a standard- or bare-metal image. Suppose you re attempting to remove Norton AntiVirus for the Mac in an automated fashion and the uninstaller distributed by Symantec isn t doing the trick. To start, look at the package contents to determine what was added to the system. You can find the contents from the Bill of Materials (BOM) for the package, which resides in the Contents directory in the initial installation package. Then you can simply build a shell script to remove all the files added during the installation. Note, however, that this often fails to remove all items that were installed or moved, and it can also leave settings in various locations. But there s another method to determine what files are in a package: Perform a snapshot before installation and another following. You can do this easily using the package-snapshot feature of PackageMaker, Composer, or another snapshot-based packaging utility. Rather than create a package, you use the tool to look at what was actually installed----which might include items not in the BOM. -

A business rule performs actions when conditions defined in the Business Rule Composer are true. For example, an action may modify a value in a message. The BizTalk developer creates a condition from facts, which are pieces of information the rules engine can examine. Most often, the rules engine will examine facts from the messages BizTalk directly processes. The orchestration invoking the rules engine directly provides these facts. However, sometimes a rule needs to be based on facts that are not available in the orchestration. The rules engine can retrieve these external facts with a custom fact retriever. In this example, a business rule will schedule a customer s service request only if the customer s address is in the Northwind database. The customer s address may be different each time the orchestration invokes the rules engine. The customer s address is called a short-term fact because the orchestration provides the fact every time it invokes the rules engine. However, instead of opening a new connection to the database each time the orchestration invokes the rules engine, this example reuses the same connection to the Northwind database over and over again. Reusing the database connection makes it a long-term fact. The BizTalk developer must provide long-term facts to the rules engine with the IFactRetriever interface. The custom fact retriever created in this recipe provides the connection to the Northwind database to the rules engine.
