Interface StaticContext

  • All Known Implementing Classes:
    ExpressionContext, StandaloneContext

    public interface StaticContext
    A StaticContext contains the information needed while an expression or pattern is being parsed. The information is also sometimes needed at run-time.
    • Method Detail

      • makeRuntimeContext

        StaticContext makeRuntimeContext​(NamePool pool)
        Copy the context with a different namepool
      • getSystemId

        String getSystemId()
        Get the System ID of the container of the expression. This is the containing entity (file) and is therefore useful for diagnostics. Use getBaseURI() to get the base URI, which may be different.
      • getLineNumber

        int getLineNumber()
        Get the line number of the expression within its containing entity Returns -1 if no line number is available
      • getBaseURI

        String getBaseURI()
        Get the Base URI of the stylesheet element, for resolving any relative URI's used in the expression. Used by the document() function.
      • getURIForPrefix

        String getURIForPrefix​(String prefix)
                        throws XPathException
        Get the URI for a prefix, using this Element as the context for namespace resolution
        Parameters:
        prefix - The prefix
        Throws:
        XPathException
      • makeNameCode

        int makeNameCode​(String qname,

                  throws XPathException
        Make a NameCode, using this Element as the context for namespace resolution
        Parameters:
        qname - The name as written, in the form "[prefix:]localname"
        Throws:
        XPathException
      • getFingerprint

        int getFingerprint​(String qname,
                           boolean useDefault)
                    throws XPathException
        Get a fingerprint for a name, using this as the context for namespace resolution
        Parameters:
        qname - The name as written, in the form "[prefix:]localname"
        Returns:
        -1 if the name is not already present in the name pool
        Throws:
        XPathException
      • makeNameTest

        NameTest makeNameTest​(short nodeType,
                              String qname,

                       throws XPathException
        Make a NameTest, using this element as the context for namespace resolution
        Throws:
        XPathException
      • bindVariable

        Binding bindVariable​(int fingerprint)
                      throws XPathException

        Parameters:
        fingerprint - The fingerprint of the variable name
        Returns:
        a Binding object that can be used to identify it in the Bindery
        Throws:
        XPathException - if the variable has not been declared, or if the context does not allow the use of variables
