public class XSLTransformer
extends Transformer

This actor reads an XSLT file and apply it to a dom tree. The file or URL is specified using any form acceptable to the FileParameter class.

Currently, this actor requires the Saxon XSLT processor so as to ensure reproducible results. This restriction may be relaxed in later versions of this actor.

FIXME: what should the type of the input/output ports be???.

Ptolemy II 4.0

Field Detail

styleSheetFile

public FileParameter styleSheetFile

The file name or URL from which to read. This is a string with any form accepted by FileParameter.

See Also:

FileParameter

styleSheetParameters

public PortParameter styleSheetParameters

The parameters to be used in the stylesheet. This is a record that defaults to "emptyRecord()", an expression language command that returns an empty record. For example, if the parameter used in the style sheet is named a with type int, then the styleSheetParameters has type {a = int}. If the style sheet has multiple parameters, then each of them is represented as a field of the record.

Constructor Detail

XSLTransformer

public XSLTransformer(CompositeEntity container,
                      java.lang.String name)
               throws IllegalActionException,
                      NameDuplicationException

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException

Clone the actor into the specified workspace. This calls the base class and then set the filename public member.

Overrides:

clone in class TypedAtomicActor

Parameters:

workspace - The workspace for the new object.

Returns:

A new actor.

Throws:

java.lang.CloneNotSupportedException - If a derived class contains an attribute that cannot be cloned.

See Also:

NamedObj.exportMoML(Writer, int, String), NamedObj.setDeferringChangeRequests(boolean)

fire

public void fire()
          throws IllegalActionException

Consume an XMLToken from the input and apply the XSL transform specified by the styleSheetFile parameter. If the styleSheetFile parameter does not name a file, then the input is copied to the output without modification.

Specified by:

fire in interface Executable

Overrides:

fire in class AtomicActor<TypedIOPort>

Throws:

IllegalActionException - If the parent class throws it

initialize

public void initialize()
                throws IllegalActionException

Open the XSL file named by the styleSheetFile parameter and set up the transformer.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class AtomicActor<TypedIOPort>

Throws:

IllegalActionException - If the TransformFactory class name does not start with net.sf.saxon.
