Class ProfessionalConfiguration

  • All Implemented Interfaces:
    SourceResolver, NotationSet
    Direct Known Subclasses:
    EnterpriseConfiguration
    public class ProfessionalConfiguration
extends Configuration
    This class holds details of user-selected configuration options for a set of transformations and/or queries. When running XSLT, the preferred way of setting configuration options is via the JAXP TransformerFactory interface, but the Configuration object provides a finer level of control. As yet there is no standard API for XQuery, so the only way of setting Configuration information is to use the methods on this class directly.

    As well as holding configuration settings, this class acts as a factory for classes providing service in particular areas: error handling, URI resolution, and the like. Some of these services are chosen on the basis of the current platform (Java or .NET), some vary depending whether the environment is schema-aware or not.

    The Configuration provides access to a NamePool which is used to manage all the names used in stylesheets, queries, schemas, and source and documents: the NamePool allocates integer codes to these names allowing efficient storage and comparison. Normally there will be a one-to-one relationship between a NamePool and a Configuration. It is possible, however, for several Configuration objects to share the same NamePool. Until Saxon 8.9, by default all Configuration objects shared a single NamePool unless configured otherwise; this changed in 8.9 so that the default is to allocate a new NamePool for each Configuration.

    The Configuration establishes the scope within which node identity is managed. Every document belongs to a Configuration, and every node has a distinct identity within that Configuration. In consequence, it is not possible for any query or transformation to manipulate multiple documents unless they all belong to the same Configuration.

    Saxon-EE has a subclass of the Configuration class which provides the additional services needed for schema-aware processing. The EnterpriseConfiguration also holds a cache of loaded schema components used for compiling schema-aware transformations and queries, and for validating instance documents.

    Since Saxon 8.4, the JavaDoc documentation for Saxon attempts to identify interfaces that are considered stable, and will only be changed in a backwards-incompatible way if there is an overriding reason to do so. These interfaces and methods are labelled with the JavaDoc "since" tag. The value 8.n indicates a method in this category that was introduced in Saxon version 8.n: or in the case of 8.4, that was present in Saxon 8.4 and possibly in earlier releases. (In some cases, these methods have been unchanged for a long time.) Methods without a "since" tag, although public, are provided for internal use or for use by advanced users, and are subject to change from one release to the next. The presence of a "since" tag on a class or interface indicates that there are one or more methods in the class that are considered stable; it does not mean that all methods are stable.

      • readConfigurationFile

        protected Configuration readConfigurationFile​(javax.xml.transform.Source source)
                                       throws XPathException
        Read the configuration file and construct a new Configuration (the real one)
        Overrides:
        readConfigurationFile in class Configuration
        Parameters:
        source - the source of the configuration file
        Returns:
        the Configuration that will be used for real work
        Throws:
        XPathException - if, for example, the configuration file is invalid

      • makeProfessionalConfiguration

        public static Configuration makeProfessionalConfiguration​(java.lang.ClassLoader classLoader,
                                                          java.lang.String className)
                                                   throws java.lang.RuntimeException
        Static method to instantiate a professional configuration.

        On the .NET platform, this method should not be called unless it is known that the assembly saxon9sa.dll has already been loaded. This can be achieved by an appropriate call on Assembly.Load(): for an example, see the C# Configuration.cs class in the Saxon.Api namespace.

        This method fails if Saxon-EE cannot be loaded, but it does not fail if there is no license available. In that case it returns a schema-aware configuration object, but any attempt to use schema-aware processing will fail.

        Parameters:
        classLoader - - the class loader to be used. If null, the context class loader for the current thread is used.
        className - - the name of the schema aware configuration class. Defaults to "com.saxonica.config.ProfessionalConfiguration" if null is supplied. This allows an assembly qualified name to be supplied under .NET. The class, once instantiated, must be an instance of Configuration, but despite the name of this method there is nothing that requires it to be schema-aware.
        Returns:
        the new ProfessionalConfiguration
        Throws:
        java.lang.RuntimeException - if the Saxon-PE product cannot be loaded
        Since:
        9.2 (renamed from makeSchemaAwareConfiguration)

      • bindExtensions

        public void bindExtensions​(java.lang.String uri,
                           cli.System.Type type)
        Declare a mapping from a specific namespace URI to a .NET class
        Overrides:
        bindExtensions in class Configuration
        Parameters:
        uri - - the namespace URI of the function name
        type - - the .NET class that implements the functions in this namespace

      • getEditionCode

        public java.lang.String getEditionCode()
        Get the edition code identifying this configuration: "HE", "PE" or "EE"

        the code identifying the Saxon edition associated with this configuration

      • setConfigurationProperty

        public void setConfigurationProperty​(java.lang.String name,
                                     java.lang.Object value)
        Set a property of the configuration. This method underpins the setAttribute() method of the TransformerFactory implementation, and is provided to enable setting of Configuration properties using URIs without instantiating a TransformerFactory: specifically, this may be useful when running XQuery, and it is also used by the Validator API

        From Saxon 9.9, an alternative interface is available: setConfigurationProperty(Feature, Object). The new interface is more efficient because it avoids expensive string comparisons. The old interface is retained mainly for compatibility, and also because there are a few cases where it cannot easily be replaced, for example when using composite feature URIs to delegate configuration options to the XML parser.

        Overrides:
        setConfigurationProperty in class Configuration
        Parameters:
        name - the URI identifying the property to be set. See the class FeatureKeys for constants representing the property names that can be set.
        value - the value of the property
        Throws:
        java.lang.IllegalArgumentException - if the property name is not recognized or if the value is not a valid value for the named property

      • setExtensionBinder

        public void setExtensionBinder​(java.lang.String scheme,
                               FunctionLibrary binder)
        Set the FunctionLibrary used to bind calls on extension functions. This allows the rules for identifying extension functions to be customized (in principle, it would allow support for extension functions in other languages to be provided).

        When an application supplies its own FunctionLibrary for binding extension functions, this replaces the default binding mechanism for Java extension functions, namely JavaExtensionLibrary. It thus disables the function libraries for built-in Saxon extensions and for EXSLT extensions. It is possible to create a function library that adds to the existing mechanisms, rather than replacing them, by supplying as the FunctionLibrary a FunctionLibraryList that itself contains two FunctionLibrary objects: a JavaExtensionLibrary, and a user-written FunctionLibrary.

        Parameters:
        scheme - The scheme served by the extension binder. Typically this will be one of "java" or "clitype". However, user-defined extension binders for other schemes can be registered. Note that the scheme name does not have to be related to the actual namespace used in function calls; all registered function libraries have the opportunity to bind any extension function call. The significance is purely local to this class: setting an extension binder for a given scheme replaces the existing extension binder for that scheme. The two schemes used by Saxon itself are "java" for dynamically-bound Java extension functions, and "clitype" for dynamically-bound .NET extension functions
        binder - The FunctionLibrary object used to locate implementations of extension functions, based on their name and arity

      • getExtensionBinder

        public FunctionLibrary getExtensionBinder​(java.lang.String scheme)
        Get the FunctionLibrary used to bind calls on extension functions on the specified platform.

        This mechanism is for advanced users only, and the details are subject to change.

        Parameters:
        scheme - The URI scheme served by the extension binder. This will typically be one of "java" or "clitype". On the Java platform, the only scheme currently supported is "java"; on the .NET platform, the "java" and "clitype" schemes coexist.
        Returns:
        the registered FunctionLibrary for extension functions if one has been registered; or null otherwise

      • bindSaxonExtensionFunction

        Parameters:
        name - the name of the required function
        arity - the arity of the required function
        Returns:
        the requested function, or null if there is no such function. Note that some functions (those with particular context dependencies) may be unsuitable for dynamic calling.

        an XDM map containing entries representing the public instance-level methods available in the object, to the extent that they have unique names.

      • resolveSource

        public javax.xml.transform.Source resolveSource​(javax.xml.transform.Source source,
                                                Configuration config)
                                         throws XPathException
        Resolve a Source.
        Specified by:
        resolveSource in interface SourceResolver
        Overrides:
        resolveSource in class Configuration
        Parameters:
        source - A source object, typically the source supplied as the first argument to Transformer.transform(javax.xml.transform.Source, javax.xml.transform.Result) or similar methods.
        config - The Configuration. This provides the SourceResolver with access to configuration information; it also allows the SourceResolver to invoke the resolveSource() method on the Configuration object as a fallback implementation.
        Returns:
        a source object that Saxon knows how to process. This must be an instance of one of the classes StreamSource, SAXSource, DOMSource, AugmentedSource, NodeInfo, or PullSource. Return null if the Source object is not recognized
        Throws:
        XPathException - if the Source object is recognized but cannot be processed

      • makeMode

        public SimpleMode makeMode​(StructuredQName modeName,
                           CompilerInfo compilerInfo)
        Make a new Mode - this can be overridden in subclasses to produce optimized variants
        Overrides:
        makeMode in class Configuration
        Parameters:
        modeName - the name of the mode
        compilerInfo - information on the compiler, that can alter rule optimization
        Returns:
        an instantiated Mode
