Class SchemaNamespaceSupport

  • All Implemented Interfaces:
    NamespaceContext

    public class SchemaNamespaceSupport
    extends NamespaceSupport
    This class customizes the behaviour of the util.NamespaceSupport class in order to easily implement some features that we need for efficient schema handling. It will not be generally useful.

    • Constructor Detail

      • SchemaNamespaceSupport

        public SchemaNamespaceSupport​(Element schemaRoot,
                                      SymbolTable symbolTable)
    • Method Detail

      • setEffectiveContext

        public void setEffectiveContext​(String[] namespaceDecls)
        This method takes a set of Strings, as stored in a NamespaceSupport object, and "fools" the object into thinking that this is one unified context. This is meant to be used in conjunction with things like local elements, whose declarations may be deeply nested but which for all practical purposes may be regarded as being one level below the global element--at least with regard to namespace declarations. It's worth noting that the context from which the strings are being imported had better be using the same SymbolTable.
      • getEffectiveLocalContext

        public String[] getEffectiveLocalContext()
        This method returns an array of Strings, as would be stored in a NamespaceSupport object. This array contains all declarations except those at the global level.
      • makeGlobal

        public void makeGlobal()
      • getURI

        public String getURI​(String prefix)
        Description copied from interface: NamespaceContext
        Look up a prefix and get the currently-mapped Namespace URI.

        This method looks up the prefix in the current context. If no mapping is found, this methods will continue lookup in the parent context(s). Use the empty string ("") for the default Namespace.

        Specified by:
        getURI in interface NamespaceContext
        Overrides:
        getURI in class NamespaceSupport
        Parameters:
        prefix - The prefix to look up.
        Returns:
        The associated Namespace URI, or null if the prefix is undeclared in this context.
