Interface StaticContext

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 Summary

bindVariable(int fingerprint)
Bind a variable to an object that can be used to refer to it
boolean
forwardsCompatibleModeIsEnabled()
Determine whether forwards-compatible mode is enabled
String
getBaseURI()
Get the Base URI of the stylesheet element, for resolving any relative URI's used in the expression.
Class
getExternalJavaClass(String uri)
Get an external Java class corresponding to a given namespace prefix, if there is one.
int
getFingerprint(String qname, boolean useDefault)
Get a fingerprint for a name, using this as the context for namespace resolution
int
getLineNumber()
Get the line number of the expression within its containing entity Returns -1 if no line number is available
Function
getStyleSheetFunction(int fingerprint)
String
getSystemId()
Get the System ID of the container of the expression.
String
getURIForPrefix(String prefix)
Get the URI for a prefix, using this Element as the context for namespace resolution
String
getVersion()
Get the effective XSLT version in this region of the stylesheet
boolean
isElementAvailable(String qname)
Determine if an extension element is available
boolean
isExtensionNamespace(short uriCode)

Method Details

allowsKeyFunction

public boolean allowsKeyFunction()
Determine whether the key() function is permmitted in this context


bindVariable

public Binding bindVariable(int fingerprint)
            throws XPathException
Bind a variable to an object that can be used to refer to it

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


forwardsCompatibleModeIsEnabled

public boolean forwardsCompatibleModeIsEnabled()
            throws XPathException
Determine whether forwards-compatible mode is enabled


getBaseURI

public 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.


getExternalJavaClass

public Class getExternalJavaClass(String uri)
            throws TransformerException
Get an external Java class corresponding to a given namespace prefix, if there is one.

Parameters:
uri - The namespace URI corresponding to the prefix used in the function call.

Returns:
the Java class if a suitable class exists, otherwise return null.


getFingerprint

public 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


getLineNumber

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


getStyleSheetFunction

public Function getStyleSheetFunction(int fingerprint)
            throws XPathException


getSystemId

public 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.


getURIForPrefix

public 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


getVersion

public String getVersion()
Get the effective XSLT version in this region of the stylesheet


isElementAvailable

public boolean isElementAvailable(String qname)
            throws XPathException
Determine if an extension element is available


isExtensionNamespace

public boolean isExtensionNamespace(short uriCode)
            throws XPathException
Determine whether a given URI code identifies an extension element namespace


isFunctionAvailable

public boolean isFunctionAvailable(String qname)
            throws XPathException
Determine if a function is available


makeNameCode

public int makeNameCode(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"


makeNameTest

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

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