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

setSecureProcessing

public void setSecureProcessing(boolean flag)

Set the state of the secure processing feature.

isSecureProcessing

public boolean isSecureProcessing()

Return the state of the secure processing feature.

getAvailableElements

public java.util.HashMap 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()

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

Usage:

**For internal use only**

getAttributeSetComposed

public java.util.ArrayList 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.

See Also:

literal-result-element in XSLT Specification

getTemplateListComposed

public final TemplateList getTemplateListComposed()

Accessor method to retrieve the TemplateList associated with this StylesheetRoot.

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,

                                        boolean quietConflictWarnings,
                                        DTM dtm)
                                 throws TransformerException

Get an "xsl:template" property by node match. This looks in the imports as well as this stylesheet.

Parameters:

xctxt - non-null reference to XPath runtime execution context.

targetNode - non-null reference of node that the template must match.

mode - qualified name of the node, or null.

quietConflictWarnings - true if conflict warnings should not be reported.
