Interface Platform

  • All Known Implementing Classes:
    JavaPlatform, JavaPlatformEE, JavaPlatformPE

      • makeCollation

        StringCollator makeCollation​(Configuration config,
                             java.util.Properties props,

                      throws XPathException
        Obtain a collation with a given set of properties. The set of properties is extensible and variable across platforms. Common properties with example values include lang=en-GB, strength=primary, case-order=upper-first, ignore-modifiers=yes, alphanumeric=yes. Properties that are not supported are generally ignored; however some errors, such as failing to load a requested class, are fatal.
        Parameters:
        config - the configuration object
        props - the desired properties of the collation
        uri - the collation URI
        Returns:
        a collation with these properties

        XPathException - if a fatal error occurs

      • canReturnCollationKeys

        boolean canReturnCollationKeys​(StringCollator collation)
        Given a collation, determine whether it is capable of returning collation keys. The essential property of collation keys is that if two values are equal under the collation, then the collation keys are equal under the equals() method.
        Parameters:
        collation - the collation being examined, provided as a Comparator
        Returns:
        true if this collation can supply collation keys

      • getCollationKey

        AtomicMatchKey getCollationKey​(SimpleCollation namedCollation,
                               java.lang.String value)
        Given a collation, get a collation key. The essential property of collation keys is that if two values are equal under the collation, then the collation keys are equal under the equals() method.
        Parameters:
        namedCollation - the collation in use
        value - the string whose collation key is required
        Returns:
        a representation of the collation key, such that two collation keys are equal() if and only if the string values they represent are equal under the specified collation.
        Throws:
        java.lang.ClassCastException - if the collation is not one that is capable of supplying collation keys (this should have been checked in advance)

      • hasICUCollator

        boolean hasICUCollator()
        Indicate whether the ICU library is available and supports Collations
        Returns:
        true if the ICU library class for collations appears to be loaded

      • hasICUNumberer

        boolean hasICUNumberer()
        Indicate whether the ICU library is available and supports Numberers
        Returns:
        true if the ICU library class for rule-based numbering appears to be loaded

      • makeUcaCollator

        StringCollator makeUcaCollator​(java.lang.String uri,
                               Configuration config)
                        throws XPathException
        If available, make a UCA collation. Depending on the Saxon edition and licensing, this will use the ICU-J Library if available, or the built-in Java collation support otherwise.
        Parameters:
        uri - the collation URI (which will always be a UCA collation URI as defined in XSLT 3.0)
        config - the Saxon configuration
        Returns:
        the collation, or null if not available
        Throws:
        XPathException - if the URI is malformed in some way

      • setDefaultSAXParserFactory

        void setDefaultSAXParserFactory​(Configuration config)
        Set the default XML parser to be loaded by the SAXParserFactory on this platform. Needed because the Apache catalog resolver uses the SAXParserFactory to instantiate a parser, and if not customized this causes a failure on the .NET platform.
        Parameters:
        config - the Saxon configuration
        Since:
        9.4

      • JAXPStaticContextCheck

        Checks if the supplied static context is an instance of the JAXP static context. On Java we create namespace information from the JAXP XPath static context. On the .NET platform we do nothing.
        Parameters:
        retainedStaticContext - If the static context is a JAXPStaticContext, then its namespaces are used to update the retainedStaticContext
        sc - the possible JAXPStaticContext
