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 Details

    • getConfiguration

      Configuration getConfiguration()
      Get the system configuration
    • makeEarlyEvaluationContext

      XPathContext makeEarlyEvaluationContext()
      Construct a dynamic context for early evaluation of constant subexpressions.
    • getLocationMap

      LocationMap getLocationMap()
      Get the location map. This is a mapping from short location ids held with each expression or subexpression, to a fully-resolved location in a source stylesheet or query.
    • issueWarning

      void issueWarning(String s, SourceLocator locator)
      Issue a compile-time warning
    • getSystemId

      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

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

      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

      String getURIForPrefix(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

      NamePool getNamePool()
      Get the NamePool used for compiling expressions
    • bindVariable

      VariableReference bindVariable(int fingerprint) throws StaticError
      Bind a variable used in this element to the XSLVariable element in which it is declared
      Parameters:
      fingerprint - the name of the variable
      Returns:
      a VariableReference representing the variable reference, suitably initialized to refer to the corresponding variable declaration
      Throws:
      StaticError
    • getFunctionLibrary

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

      Comparator getCollation(String name)
      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.
    • getDefaultCollationName

      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

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

      String getDefaultFunctionNamespace()
      Get the default function namespace
    • isInBackwardsCompatibleMode

      boolean isInBackwardsCompatibleMode()
      Determine whether Backwards Compatible Mode is used
    • isImportedSchema

      boolean isImportedSchema(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).
    • getImportedSchemaNamespaces

      Set getImportedSchemaNamespaces()
      Get the set of imported schemas
      Returns:
      a Set, the set of URIs representing the names of imported schemas
    • isAllowedBuiltInType

      boolean isAllowedBuiltInType(AtomicType type)
      Determine whether a built-in type is available in this context. This method caters for differences between host languages as to which set of types are built in.
      Parameters:
      type - the supposedly built-in type. This will always be a type in the XS or XDT namespace.
      Returns:
      true if this type can be used in this static context
    • getNamespaceResolver

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