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

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

Throws:

XPathException

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"

Throws:

XPathException

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

Throws:

XPathException

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
