(This is similar to the new C# inferred type expressions via the var keyword.) The let expression doesn't need to work solely with data. You can use it to define functions, which F# recognizes as first-class concepts. So, for example, the following defines an add function that takes ...
More importantly, XPath defines a common syntax so you can retrieve nodes from within classes that implement the XML document object model (DOM) as well as from XSLT. In the Microsoft® .NET Framework, the XPath query language is fully supported through the classes defined in the System.Xml...
Instead, in defining generic code a "code factory" is created. The factory code can then be used by referencing code in order to construct code that can be used directly. Let's look at this idea first with a generic method. The code in Figure 5 defines and references a generic method ...
Since Cov ( ξ i , ξ j ) is symmetric and positive, its inverse is also symmetric and positive, i.e., it is a positive bilinear form, therefore, the above expression defines a scalar product. Then, the optimal test for an alternative spectrum ξ ¯ can be written in the elegant ...

This object defines an executable process. The data source, index, and indexer are created in this step.Accept the system-generated value for the Indexer name (hotels-sample-indexer). For this quickstart, use the default option to run the indexer once, immediately. The hosted data is static ...
interface Defines an interface. namespace Allows you to control the visibility of definitions. package Allows you to organize your code into discrete groups that can be imported by other scripts. set Defines a setter, which is a method that appears in the public interface as a property. var ...
Have a look at the configuration file 'gaiandb_config.properties'. This defines logical tables (LT0, LT1, ..), and their federated physical data sources (LT0_DS0, LT0_DS1, ..). You can find out more about these configuration settings here. Verify...

To handle any transaction-oriented functionality, you can add a route that specifies a method (called an “action” in routing-speak) on the controller by name rather than by HTTP type. The following example defines a URL that routes a request to a method called AssignCustomerToOrder and...
