All Implemented Interfaces:

java.io.Serializable, javax.xml.transform.SourceLocator, Container, StaticContext, NamespaceResolver
```
public class JAXPXPathStaticContext
extends AbstractStaticContext
implements StaticContext, NamespaceResolver, Container
```
A StandaloneContext provides a context for parsing an XPath expression in a context other than a stylesheet. In particular, it is used to support the JAXP 1.3 XPath API. The JAXP API does not actually expose the StaticContext object directly; rather, the static context (namespaces, variables, and functions) is manipulated through the XPath object, implemented in Saxon by the XPathEvaluator

```
public JAXPXPathStaticContext(Configuration config)
```
    Create a StandaloneContext using a specific Configuration.
    
    Parameters:
    
    config - the Configuration. For schema-aware XPath expressions, this must be a SchemaAwareConfiguration.
- Method Detail
  - setNamespaceContext
```
public void setNamespaceContext(javax.xml.namespace.NamespaceContext context)
```
    Supply the NamespaceContext used to resolve namespaces.
  - getNamespaceContext

```
public SlotManager getStackFrameMap()
```
    Get the stack frame map containing the slot number allocations for the variables declared in this static context
  - setXPathVariableResolver
```
public void setXPathVariableResolver(javax.xml.xpath.XPathVariableResolver resolver)
```
    Set an XPathVariableResolver. This is used to resolve variable references if no variable has been explicitly declared.
    
    Parameters:
    
    resolver - A JAXP 1.3 XPathVariableResolver
  - getXPathVariableResolver
```
public javax.xml.xpath.XPathVariableResolver getXPathVariableResolver()
```
    Get the XPathVariableResolver
  - setXPathFunctionResolver
```
public void setXPathFunctionResolver(javax.xml.xpath.XPathFunctionResolver xPathFunctionResolver)
```
  - getXPathFunctionResolver
```
public javax.xml.xpath.XPathFunctionResolver getXPathFunctionResolver()
```
  - getURIForPrefix
```
public java.lang.String getURIForPrefix(java.lang.String prefix)
                                 throws XPathException
```
    Get the URI for a prefix, using the declared namespaces as the context for namespace resolution. The default namespace is NOT used when the prefix is empty. This method is provided for use by the XPath parser.
    
    Specified by:
    
    getURIForPrefix in interface StaticContext
    
    Parameters:
    
    prefix - The prefix
    
    Returns:
    
    the corresponding namespace URI
    
    Throws:
    
    XPathException - if the prefix is not declared
  - getNamespaceResolver
```
public NamespaceResolver getNamespaceResolver()
```
    Description copied from interface: StaticContext
    
    Get a namespace resolver to resolve the namespaces declared in this static context.
    
    Specified by:
    
    getNamespaceResolver in interface StaticContext
    
    Returns:
    
    a namespace resolver.
  - getURIForPrefix
```
public java.lang.String getURIForPrefix(java.lang.String prefix,
                                        boolean useDefault)
```
    Get the namespace URI corresponding to a given prefix. Return null if the prefix is not in scope. This method searches any namespace context supplied using setNamespaceContext(javax.xml.namespace.NamespaceContext).
    
    Specified by:
    
    getURIForPrefix in interface NamespaceResolver
    
    Parameters:
    
    prefix - the namespace prefix
    
    useDefault - true if the default namespace for elements and types is to be used when the prefix is ""
    
    Returns:
    
    the uri for the namespace, or null if the prefix is not in scope. Return "" if the prefix maps to the null namespace.
  - iteratePrefixes
```
public java.util.Iterator iteratePrefixes()
```
    Get an iterator over all the prefixes declared in this namespace context. This method is implemented only in the case where the NamespaceContext supplied using setNamespaceContext(javax.xml.namespace.NamespaceContext) is an instance of Saxon's NamespaceResolver class. In other cases the method throws an UnsupportedOperationException
    
    Specified by:
    
    iteratePrefixes in interface NamespaceResolver
    
    Returns:
    
    an iterator over all the inscope namespace prefixes, if available
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the NamespaceContext object is not a NamespaceResolver.
  - bindVariable
```
public final VariableReference bindVariable(StructuredQName qName)
                                     throws XPathException
```
    Bind a variable used in an XPath Expression to the XSLVariable element in which it is declared. This method is provided for use by the XPath parser, and it should not be called by the user of the API.
    
    Specified by:
    
    bindVariable in interface StaticContext
    
    Parameters:
    
    qName -
    
    Returns:
    
    a VariableReference representing the variable reference, suitably initialized to refer to the corresponding variable declaration
    
    Throws:
    
    XPathException - if no VariableResolver has been supplied.
  - importSchema
```
public void importSchema(javax.xml.transform.Source source)
                  throws SchemaException
```
    Import a schema. This is possible only if the schema-aware version of Saxon is being used, and if the Configuration is a SchemaAwareConfiguration. Having imported a schema, the types defined in that schema become part of the static context.
    
    Parameters:
    
    source - A Source object identifying the schema document to be loaded
    
    Throws:
    
    SchemaException - if the schema contained in this document is invalid
    
    java.lang.UnsupportedOperationException - if the configuration is not schema-aware
  - 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).
    
    Specified by:
    
    isImportedSchema in interface StaticContext
    
    Parameters:
    
    namespace - the target namespace in question
    
    Returns:
    
    true if schema components for the given namespace have been imported into the schema-aware configuration
  - getImportedSchemaNamespaces
```
public java.util.Set getImportedSchemaNamespaces()
```
    Get the set of imported schemas
    
    Specified by:
    
    getImportedSchemaNamespaces in interface StaticContext
    
    Returns:
    
    a Set, the set of URIs representing the names of imported schemas
