Class PreparedStylesheet

java.lang.Object
  extended by net.sf.saxon.expr.instruct.Executable
      extended by net.sf.saxon.PreparedStylesheet
All Implemented Interfaces:
Serializable, Templates

public class PreparedStylesheet
extends Executable
implements Templates, Serializable

This PreparedStylesheet class represents a Stylesheet that has been prepared for execution (or "compiled").

Note that the PreparedStylesheet object does not contain a reference to the source stylesheet tree (rooted at an XSLStyleSheet object). This allows the source tree to be garbage-collected when it is no longer required.

Returns:
the DecimalFormatManager containing the named xsl:decimal-format definitions

setUsesTunnelParameters

public void setUsesTunnelParameters()

Returns:
true if the stylesheet uses tunnel parameters.

prepare

loadStylesheetModule

public DocumentImpl loadStylesheetModule(Source styleSource)
                                  throws XPathException

setRuleManager

public void setRuleManager(RuleManager rm)
Set the RuleManager that handles template rules

Parameters:
rm - the RuleManager containing details of all the template rules

getRuleManager

public RuleManager getRuleManager()
Get the RuleManager which handles template rules

Returns:
the RuleManager registered with setRuleManager

getNamedTemplate

public Template getNamedTemplate(StructuredQName qName)
Get the named template with a given name.

Parameters:
qName - The template name
Returns:
The template (of highest import precedence) with this name if there is one; null if none is found.

putNamedTemplate

public void putNamedTemplate(StructuredQName templateName,
                             Template template)
Register the named template with a given name

Parameters:
templateName - the name of a named XSLT template
template - the template

iterateNamedTemplates

public Iterator<Template> iterateNamedTemplates()
Iterate over all the named templates defined in this Executable

Returns:
an iterator, the items returned being of class Template

explainNamedTemplates

public void explainNamedTemplates(ExpressionPresenter presenter)
Explain the expression tree for named templates in a stylesheet

Parameters:
presenter - destination for the explanatory output

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,

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

getCompilerInfo

public CompilerInfo getCompilerInfo()
Get the CompilerInfo containing details of XSLT compilation options

Returns:
the CompilerInfo containing compilation options
Since:
9.2

explain

public void explain(ExpressionPresenter presenter)
Produce an XML representation of the compiled and optimized stylesheet

Parameters:

                                      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).
