Constructor Detail

### StylesheetRoot

    public StylesheetRoot(ErrorListener errorListener)
                   throws TransformerConfigurationException

  Uses an XSL stylesheet document.
  Throws:
    TransformerConfigurationException - if the baseIdentifier can not be resolved to a URL.

### StylesheetRoot

    public StylesheetRoot(XSLTSchema schema,
                          ErrorListener listener)
                   throws TransformerConfigurationException

  Creates a StylesheetRoot and retains a pointer to the schema used to create this StylesheetRoot. The schema may be needed later for an element-available() function call.
  Parameters:
    `schema` - The schema used to create this stylesheet
  Throws:
    TransformerConfigurationException - if the baseIdentifier can not be resolved to a URL.

Method Detail

### isRoot

    public boolean isRoot()

  Tell if this is the root of the stylesheet tree.
  Returns:
    True since this is the root of the stylesheet tree.
  Overrides:
    isRoot in class Stylesheet

### getAvailableElements

    public java.util.Hashtable getAvailableElements()

  Get the hashtable of available elements.
  Returns:
    table of available elements, keyed by qualified names, and with values of the same qualified names.

### getExtensionNamespacesManager

    public ExtensionNamespacesManager getExtensionNamespacesManager()

  Only instantiate an ExtensionNamespacesManager if one is called for (i.e., if the stylesheet contains extension functions and/or elements).

### getExtensions

    public java.util.Vector getExtensions()

  Get the vector of extension namespaces. Used to provide the extensions table access to a list of extension namespaces encountered during composition of a stylesheet.

### newTransformer

    public Transformer newTransformer()

  Create a new transformation context for this Templates object.
  Specified by:
    newTransformer in interface Templates
  Returns:
    A Transformer instance, never null.

### getDefaultOutputProps

    public java.util.Properties getDefaultOutputProps()

### getOutputProperties

    public java.util.Properties getOutputProperties()

  Get the static properties for xsl:output. The object returned will be a clone of the internal values, and thus it can be mutated without mutating the Templates object, and then handed in to the process method.

  For XSLT, Attribute Value Templates attribute values will be returned unexpanded (since there is no context at this point).

  Specified by:
    getOutputProperties in interface Templates
  Returns:
    A Properties object, not null.

### recompose

    public void recompose()
                   throws TransformerException

  Recompose the values of all "composed" properties, meaning properties that need to be combined or calculated from the combination of imported and included stylesheets. This method determines the proper import precedence of all imported stylesheets. It then iterates through all of the elements and properties in the proper order and triggers the individual recompose methods.
  Throws:
    TransformerException -

### getGlobalImport

    public StylesheetComposed getGlobalImport(int i)

  Get a stylesheet from the global import list. TODO: JKESS PROPOSES SPECIAL-CASE FOR NO IMPORT LIST, TO MATCH COUNT.
  Parameters:
    `i` - Index of stylesheet to get from global import list
  Returns:
    The stylesheet at the given index

### getGlobalImportCount

    public int getGlobalImportCount()

  Get the total number of imports in the global import list.
  Returns:
    The total number of imported stylesheets, including the root stylesheet, thus the number will always be 1 or greater. TODO: JKESS PROPOSES SPECIAL-CASE FOR NO IMPORT LIST, TO MATCH DESCRIPTION.

### getImportNumber

    public int getImportNumber(StylesheetComposed sheet)

  Given a stylesheet, return the number of the stylesheet in the global import list.
  Parameters:
    `sheet` - The stylesheet which will be located in the global import list.
  Returns:
    The index into the global import list of the given stylesheet, or -1 if it is not found (which should never happen).

### getOutputComposed

    public OutputProperties getOutputComposed()

  Get the combined "xsl:output" property with the properties combined from the included stylesheets. If a xsl:output is not declared in this stylesheet or an included stylesheet, look in the imports. Please note that this returns a reference to the OutputProperties object, not a cloned object, like getOutputProperties does.
  Returns:
    non-null reference to composed output properties object.
  See Also:
    output in XSLT Specification

### isOutputMethodSet

    public boolean isOutputMethodSet()

  **For internal use only** Find out if an output method has been set by the user.
  Returns:
    Value indicating whether an output method has been set by the user

### getAttributeSetComposed

    public java.util.Vector getAttributeSetComposed(QName name)
                                             throws java.lang.ArrayIndexOutOfBoundsException

  Get a list "xsl:attribute-set" properties that match the qname.
  Parameters:
    `name` - Qualified name of attribute set properties to get
  Returns:
    A vector of attribute sets matching the given name
  Throws:
    java.lang.ArrayIndexOutOfBoundsException -
  See Also:
    attribute-sets in XSLT Specification

### getDecimalFormatComposed

    public java.text.DecimalFormatSymbols getDecimalFormatComposed(QName name)

  Given a valid element decimal-format name, return the decimalFormatSymbols with that name.

  It is an error to declare either the default decimal-format or a decimal-format with a given name more than once (even with different import precedence), unless it is declared every time with the same value for all attributes (taking into account any default values).

  Which means, as far as I can tell, the decimal-format properties are not additive.

  Parameters:
    `name` - Qualified name of the decimal format to find
  Returns:
    DecimalFormatSymbols object matching the given name or null if name is not found.

### getKeysComposed

    public java.util.Vector getKeysComposed()

  Get the composed "xsl:key" properties.
  Returns:
    A vector of the composed "xsl:key" properties.
  See Also:
    key in XSLT Specification

### getNamespaceAliasComposed

    public NamespaceAlias getNamespaceAliasComposed(java.lang.String uri)

  Get the "xsl:namespace-alias" property. Return the NamespaceAlias for a given namespace uri.
  Parameters:
    `uri` - non-null reference to namespace that is to be aliased.
  Returns:
    NamespaceAlias that matches uri, or null if no match.

  Returns:
    The composed `TemplateList`.

### setTemplateListComposed

    public final void setTemplateListComposed(TemplateList templateList)

  Mutator method to set the `TemplateList` associated with this StylesheetRoot. This method should only be used by the compiler. Normally, the template list is built during the recompose process and should not be altered by the user.
  Parameters:
    `templateList` - The new `TemplateList` for this StylesheetRoot.

### getTemplateComposed

    public ElemTemplate getTemplateComposed(XPathContext xctxt,
                                            int targetNode,
