TransformerConfigurationException - if compilation of the stylesheet fails for any reason

loadStylesheetModule

public DocumentImpl loadStylesheetModule(Source styleSource,
                                         StyleNodeFactory nodeFactory)
                                  throws XPathException

Build the tree representation of a stylesheet module

Parameters:

styleSource - the source of the module

nodeFactory - the StyleNodeFactory used for creating element nodes in the tree

Returns:

the root Document node of the tree containing the stylesheet module

Throws:

XPathException - if XML parsing or tree construction fails

setStylesheetDocument

protected void setStylesheetDocument(DocumentImpl doc,
                                     StyleNodeFactory snFactory)
                              throws XPathException

Create a PreparedStylesheet from a supplied DocumentInfo Note: the document must have been built using the StyleNodeFactory

Parameters:

doc - the document containing the stylesheet module

snFactory - the StyleNodeFactory used to build the tree

Throws:

XPathException - if the document supplied is not a stylesheet

getExecutable

public Executable getExecutable()

Get the associated executable

Returns:

the Executable for this stylesheet

isCompileWithTracing

public boolean isCompileWithTracing()

Determine whether trace hooks are included in the compiled code.

Returns:

true if trace hooks are included, false if not.

Since:

8.9

getOutputProperties

public Properties getOutputProperties()

Get the properties for xsl:output. JAXP method. 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.

In Saxon, the properties object is a new, empty, Properties object that is backed by the live properties to supply default values for missing properties. This means that the property values must be read using the getProperty() method. Calling the get() method on the underlying Hashtable will return null.

In Saxon 8.x, this method gets the output properties for the unnamed output format in the stylesheet.

Specified by:

getOutputProperties in interface Templates

Returns:

A Properties object reflecting the output properties defined for the default (unnamed) output format in the stylesheet. It may be mutated and supplied to the setOutputProperties() method of the Transformer, without affecting other transformations that use the same stylesheet.

See Also:

Transformer.setOutputProperties(java.util.Properties)

reportError

public void reportError(TransformerException err)
                 throws TransformerException

Report a compile time error. This calls the errorListener to output details of the error, and increments an error count.

Parameters:

err - the exception containing details of the error

Throws:

TransformerException - if the ErrorListener decides that the error should be reported

getErrorCount

public int getErrorCount()

Get the number of errors reported so far

Returns:

the number of errors reported

reportWarning

public void reportWarning(TransformerException err)

Report a compile time warning. This calls the errorListener to output details of the warning.

Parameters:

err - an exception holding details of the warning condition to be reported

getCachedStylesheet

public PreparedStylesheet getCachedStylesheet(String href,
                                              String baseURI)

Get a "next in chain" stylesheet. This method is intended for internal use.

Parameters:

href - the relative URI of the next-in-chain stylesheet

baseURI - the baseURI against which this relativeURI is to be resolved

Returns:

the cached stylesheet if present in the cache, or null if not

putCachedStylesheet

public void putCachedStylesheet(String href,
                                String baseURI,
                                PreparedStylesheet pss)

Save a "next in chain" stylesheet in compiled form, so that it can be reused repeatedly. This method is intended for internal use.

Parameters:

href - the relative URI of the stylesheet

baseURI - the base URI against which the relative URI is resolved

pss - the prepared stylesheet object to be cached

                                      throws TransformerConfigurationException

Get the stylesheet specification(s) associated via the xml-stylesheet processing instruction (see http://www.w3.org/TR/xml-stylesheet/) with the document document specified in the source parameter, and that match the given criteria. Note that it is possible to return several stylesheets, in which case they are applied as if they were a list of imports or cascades.

Parameters:

config - The Saxon Configuration

source - The XML source document.

media - The media attribute to be matched. May be null, in which case the prefered templates will be used (i.e. alternate = no).

charset - The value of the charset attribute to match. May be null.

Returns:

A Source object suitable for passing to the TransformerFactory.
