Class XsltExecutable

java.lang.Object

net.sf.saxon.s9api.XsltExecutable

public class XsltExecutable
extends java.lang.Object

An XsltExecutable represents the compiled form of a stylesheet. To execute the stylesheet, it must first be loaded to form an XsltTransformer.

An XsltExecutable is immutable, and therefore thread-safe. It is simplest to load a new XsltTransformer each time the stylesheet is to be run. However, the XsltTransformer is serially reusable within a single thread.

An XsltExecutable is created by using one of the compile methods on the XsltCompiler class.

Method Detail

getProcessor

public Processor getProcessor()

Get the Processor that was used to create this XsltExecutable

Returns:

the original Processor object

Since:

9.6

load

public XsltTransformer load()

Load the stylesheet to prepare it for execution. This version of the load() method creates an XsltTransformer which offers interfaces for stylesheet invocation corresponding to those described in the XSLT 2.0 specification. It can be used with XSLT 2.0 or XSLT 3.0 stylesheets, but does not offer new XSLT 3.0 functionality such as the ability to supply parameters to the initial template, or the ability to invoke stylesheet-defined functions, or the ability to return an arbitrary sequence as a result without wrapping it in a document node. If such facilities are required, use the method load30() in preference.

Returns:

An XsltTransformer. The returned XsltTransformer can be used to set up the dynamic context for stylesheet evaluation, and to run the stylesheet.

load30

public Xslt30Transformer load30()

Load the stylesheet to prepare it for execution. This version of the load() method creates an Xslt30Transformer which offers interfaces for stylesheet invocation corresponding to those described in the XSLT 3.0 specification. It can be used with XSLT 2.0 or XSLT 3.0 stylesheets, and in both cases it offers new XSLT 3.0 functionality such as the ability to supply parameters to the initial template, or the ability to invoke stylesheet-defined functions, or the ability to return an arbitrary sequence as a result without wrapping it in a document node.

Returns:

An Xslt30Transformer. The returned Xslt30Transformer can be used to set up the dynamic context for stylesheet evaluation, and to run the stylesheet.

explain

public void explain(Destination destination)
             throws SaxonApiException

Produce a diagnostic representation of the compiled stylesheet, in XML form.

The detailed form of this representation is not stable (or even documented).

Parameters:

destination - the destination for the XML document containing the diagnostic representation of the compiled stylesheet

Throws:

SaxonApiException

Since:

9.1

export

public void export(java.io.OutputStream destination)
            throws SaxonApiException

Produce a representation of the compiled stylesheet, in XML form, suitable for distribution and reloading. If the configuration under which the export takes place is suitably licensed, then license information will be included in the export file allowing execution of the stylesheet without any additional license.

The detailed form of the output representation is not documented.

Parameters:

destination - the destination for the XML document containing the diagnostic representation of the compiled stylesheet. The stream will be closed when writing has finished.

Throws:

SaxonApiException

Since:

9.7

export

public void export(java.io.OutputStream destination,
                   java.lang.String target)
            throws SaxonApiException

Produce a representation of the compiled stylesheet for a particular target environment, in XML form, suitable for distribution and reloading. If the configuration under which the export takes place is suitably licensed, then license information will be included in the export file allowing execution of the stylesheet without any additional license.

The detailed form of the output representation is not documented.

Requires Saxon-EE.

Parameters:

destination - the destination for the XML document containing the diagnostic representation of the compiled stylesheet. The stream will be closed when writing has finished.

target - the target environment. The only values currently recognized are "JS" and "JS2, which export the package for running under Saxon-JS 1.0 or 2.0 respectively.

Throws:

SaxonApiException

Since:

9.7

getWhitespaceStrippingPolicy

public WhitespaceStrippingPolicy getWhitespaceStrippingPolicy()

Get the whitespace stripping policy defined by this stylesheet, that is, the policy defined by the xsl:strip-space and xsl:preserve-space elements in the top-level package of this stylesheet

Returns:

a newly constructed WhitespaceStrippingPolicy based on the declarations in the top-level package of this stylesheet. This policy can be used as input to a DocumentBuilder.

getGlobalParameters

public java.util.HashMap<QName,XsltExecutable.ParameterDetails> getGlobalParameters()

Get the names of the xsl:param elements defined in this stylesheet, with details of each parameter including its required type, and whether it is required or optional

Returns:

a HashMap whose keys are the names of global parameters in the stylesheet, and whose values are XsltExecutable.ParameterDetails objects giving information about the corresponding parameter.

Since:

9.3

getUnderlyingCompiledStylesheet

public PreparedStylesheet getUnderlyingCompiledStylesheet()

Get the underlying implementation object representing the compiled stylesheet. This provides an escape hatch into lower-level APIs. The object returned by this method may change from release to release.

Returns:

the underlying implementation of the compiled stylesheet
