Interface StaticContext

All Known Implementing Classes:
StandaloneContext, ExpressionContext

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


public StaticContext makeRuntimeContext(NamePool pool)
Copy the context with a different namepool

getSystemId


public java.lang.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


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

getBaseURI


public java.lang.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


public java.lang.String getURIForPrefix(java.lang.String prefix)
                                 throws XPathException
Get the URI for a prefix, using this Element as the context for namespace resolution
Parameters:
prefix - The prefix

makeNameCode


public int makeNameCode(java.lang.String qname,
                        boolean useDefault)
                 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"

getFingerprint


public int getFingerprint(java.lang.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

makeNameTest


public NameTest makeNameTest(short nodeType,
                             java.lang.String qname,
                             boolean useDefault)
                      throws XPathException
Make a NameTest, using this element as the context for namespace resolution

makeNamespaceTest


public NamespaceTest makeNamespaceTest(short nodeType,
                                       java.lang.String prefix)
                                throws XPathException
