    • initialize

      public void initialize(Configuration config)
      Perform platform-specific initialization of the configuration
      Specified by:
      initialize in interface Platform

    • makeAbsolute

      public URI makeAbsolute(String relativeURI, String base) throws URISyntaxException
      Construct an absolute URI from a relative URI and a base URI
      Specified by:
      makeAbsolute in interface Platform
      Parameters:
      relativeURI - the relative URI
      base - the base URI
      Returns:
      the absolutized URI
      Throws:
      URISyntaxException

    • escapeSpaces

      public static String escapeSpaces(String s)
      Replace spaces by %20

    • tryToExpand

      public static String tryToExpand(String systemId)
      If a system ID can't be parsed as a URL, we'll try to expand it as a relative URI using the current directory as the base URI: MHK addition.

    • getPlatformVersion

      public String getPlatformVersion()
      Get the platform version
      Specified by:
      getPlatformVersion in interface Platform

    • getPlatformSuffix

      public String getPlatformSuffix()
      Get a suffix letter to add to the Saxon version number to identify the platform
      Specified by:
      getPlatformSuffix in interface Platform

    • getParserSource

      public Source getParserSource(StreamSource input, int validation, boolean dtdValidation, int stripspace)
      Convert a StreamSource to either a SAXSource or a PullSource, depending on the native parser of the selected platform
      Specified by:
      getParserSource in interface Platform
      Parameters:
      input - the supplied StreamSource
      validation -
      dtdValidation -
      stripspace -
      Returns:
      the PullSource or SAXSource, initialized with a suitable parser, or the original input Source, if now special handling is required or possible. This implementation always returns the original input unchanged.

    • compileRegularExpression

      public RegularExpression compileRegularExpression(CharSequence regex, boolean isXPath, CharSequence flags) throws XPathException
      Create a compiled regular expression
      Specified by:
      compileRegularExpression in interface Platform
      Parameters:
      regex - the source text of the regular expression, in XML Schema or XPath syntax
      isXPath - set to true if this is an XPath regular expression, false if it is XML Schema
      flags - the flags argument as supplied to functions such as fn:matches(), in string form
      Returns:
      the compiled regular expression
      Throws:
      XPathException - if the syntax of the regular expression or flags is incorrect

    • makeCollation

      public Comparator makeCollation(Configuration config, 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=ed-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.
      Specified by:
      makeCollation in interface Platform
      Parameters:
      config - the configuration object
      props - the desired properties of the collation
      Returns:
      a collation with these properties
      Throws:
      XPathException - if a fatal error occurs

    • canReturnCollationKeys

      public boolean canReturnCollationKeys(Comparator 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.
      Specified by:
      canReturnCollationKeys in interface Platform
      Parameters:
      collation - the collation, provided as a Comparator
      Returns:
      true if this collation can supply collation keys

    • getCollationKey

      public Object getCollationKey(Comparator collation, 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 compare correctly under the compareTo method.
      Specified by:
      getCollationKey in interface Platform
      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:
      ClassCastException - if the collation is not one that is capable of supplying collation keys (this should have been checked in advance)

    • addFunctionLibraries

      public void addFunctionLibraries(FunctionLibraryList list, Configuration config)
      Add platform-specific function libraries to the function library list
      Specified by:
      addFunctionLibraries in interface Platform

    • getExternalObjectType

      public SchemaType getExternalObjectType(String uri, String localName)
      Specified by:
      getExternalObjectType in interface Platform
