Interface StaticContext

All Known Implementing Classes:
ExpressionContext, StandaloneContext, StaticQueryContext

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.

 java.util.Comparator getCollation(java.lang.String name)
          Get a named collation.
 Configuration getConfiguration()
          Get the system configuration
 java.lang.String getDefaultCollationName()
          Get the name of the default collation.
 short getDefaultElementNamespace()
          Get the default XPath namespace, as a namespace code that can be looked up in the NamePool
 java.lang.String getDefaultFunctionNamespace()
          Get the default function namespace
 FunctionLibrary getFunctionLibrary()
          Get the function library containing all the in-scope functions available in this static context
 int getLineNumber()
          Get the line number of the expression within its containing entity Returns -1 if no line number is available
 LocationMap getLocationMap()
          Get the location map

Method Detail

getConfiguration

public Configuration getConfiguration()
Get the system configuration


getLocationMap

public LocationMap getLocationMap()
Get the location map


issueWarning

public void issueWarning(java.lang.String s)
Issue a compile-time warning


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(), doc(), resolve-uri(), and base-uri() functions. May return null if the base URI is not known.


getURIForPrefix

public java.lang.String getURIForPrefix(java.lang.String prefix)
                                 throws XPathException
Get the URI for a namespace prefix. The default namespace is NOT used when the prefix is empty.

Parameters:
prefix - The prefix
Throws:
XPathException - if the prefix is not declared

getNamePool

public NamePool getNamePool()
Get the NamePool used for compiling expressions


bindVariable

public VariableDeclaration bindVariable(int fingerprint)
                                 throws StaticError
Bind a variable used in this element to the XSLVariable element in which it is declared

StaticError

getFunctionLibrary

public FunctionLibrary getFunctionLibrary()
Get the function library containing all the in-scope functions available in this static context


getCollation

public java.util.Comparator getCollation(java.lang.String name)
                                  throws XPathException
Get a named collation.

Parameters:
name - The name of the required collation. Supply null to get the default collation.
Returns:
the collation; or null if the required collation is not found.
XPathException

getDefaultCollationName

public java.lang.String getDefaultCollationName()
Get the name of the default collation.

Returns:
the name of the default collation; or the name of the codepoint collation if no default collation has been defined

getDefaultElementNamespace

public short getDefaultElementNamespace()
Get the default XPath namespace, as a namespace code that can be looked up in the NamePool


getDefaultFunctionNamespace

public java.lang.String getDefaultFunctionNamespace()
Get the default function namespace


isInBackwardsCompatibleMode

public boolean isInBackwardsCompatibleMode()
Determine whether Backwards Compatible Mode is used


isImportedSchema

public boolean isImportedSchema(java.lang.String namespace)
Determine whether a Schema for a given target namespace has been imported. Note that the in-scope element declarations, attribute declarations and schema types are the types registered with the (schema-aware) configuration, provided that their namespace URI is registered in the static context as being an imported schema namespace. (A consequence of this is that within a Configuration, there can only be one schema for any given namespace, including the null namespace).


getNamespaceResolver

public NamespaceResolver getNamespaceResolver()
Get a namespace resolver to resolve the namespaces declared in this static context.

Returns:
a namespace resolver.
