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
- Make a NamespaceTest, using this element as the context for namespace resolution
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
isExtensionNamespace
public boolean isExtensionNamespace(short uriCode)
throws XPathException
- Determine whether a given URI code identifies an extension element namespace
forwardsCompatibleModeIsEnabled
public boolean forwardsCompatibleModeIsEnabled()
throws XPathException
- Determine whether forwards-compatible mode is enabled
getStyleSheetFunction
public Function getStyleSheetFunction(int fingerprint) throws XPathException
getExternalJavaClass
public java.lang.Class getExternalJavaClass(java.lang.String uri)
- Get an external Java class corresponding to a given namespace prefix, if there is
one.
isElementAvailable
public boolean isElementAvailable(java.lang.String qname)
throws XPathException
- Determine if an extension element is available
isFunctionAvailable
public boolean isFunctionAvailable(java.lang.String qname)
throws XPathException
- Determine if a function is available
allowsKeyFunction
public boolean allowsKeyFunction()
- Determine whether the key() function is permmitted in this context
getVersion
public java.lang.String getVersion()
