Compiler Interface

Table 10-2 summarizes the methods of available through the Compiler interface.

Table 10-2 Summary of Compiler Methods; Xsl Package

Function Summary
compile()
Compile Xsl and return its compiled binary representation.
getCompilerId()
Get compiler's Id.

compile()

Compiles Xsl and returns its compiled binary representation.

Syntax

virtual ub2* compile(
   InputSource* isrc_ptr)
throw (XslException) = 0;

Parameter Description
isrc_ptr
Xsl document

Returns

(InputSource) Xsl document in compiled binary representation


getCompilerId()

Get the compiler Id.

Syntax

virtual XslCompIdType getCompilerId() const = 0;

Returns

(XslCompIdType) Compiler's Id


getLength()

Returns length of compiled XSL document

Syntax

virtual ub4 getLength( 
   ub2* binxsl_ptr)
throw (XslException) = 0;

Parameter Description
binxsl_ptr
compiled Xsl document

Returns

(ub4) length of the document


CompTransformer Interface

Table 10-3 summarizes the methods of available through the CompTransformer interface.

Table 10-3 Summary of CompTransformer Methods; Xsl Package

Function Summary
getTransformerId()
Get transformer's Id.
setBinXsl()
Set compiled Xsl.
setSAXHandler()
Set SAX handler.
setXSL()
Set XSLT document for this transformer.
transform()
Transform the document.


getTransformerId()

Get transformer's id.

Syntax

virtual XslTrIdType getTransformerId() const = 0;

Returns

(XslTrIdType) Transformer's Id


setBinXsl()

Sets compiled Xsl.

Syntax

virtual void setBinXsl (
   ub2* binxsl_ptr)
throw (XslException) = 0;
Parameter Description
binxsl_ptr
compiled Xsl document


setSAXHandler()

Inherited from Transformer.

Syntax

virtual void setSAXHandler(
   SAXHandlerRoot* hdlr_ptr) = 0;
Parameter Description
hdlr_ptr
SAX handler pointer


setXSL()

Set XSLT document for this transformer. Should be called before the transform member function is called. It is inherited from Transform.

Syntax

virtual void setXSL (
   InputSource* isrc_ptr)
throw (XslException) = 0;
Parameter Description
isrc_ptr
instance document to process


transform()

Transforms the document. Throws an exception if an XSLT document is not set by a previous call to setXSL. Inherited from Transform.

Syntax Description
virtual NodeRef< Node>* transform(
   nputSource* isrc_ptr)
throw (XslException) = 0;
Transform the document and return DOM.
virtual void transform(
   InputSource* isrc_ptr,
   SAXHandlerRoot* hdlr_ptr)
throw (XslException) = 0;
Transform the document and return SAX events.

Parameter Description
isrc_ptr
instance document to process
hdlr_ptr
SAX handler pointer

Returns

(DocumentRef) document tree of new document


Transformer Interface

Table 10-4 summarizes the methods of available through the Transformer interface.

Table 10-4 Summary of Transformer Methods; Xsl Package

Function Summary
getTransformerId()
Get transformer's Id.
setSAXHandler()
Set SAX handler.
setXSL()
Set XSLT document for this transformer.
transform()
Transform the document and return SAX events.


getTransformerId()

Gets transformer's id.

Syntax

virtual XslTrIdType getTransformerId() const = 0;

Returns

Parameter Description
hdlr_ptr
SAX handler pointer

Syntax

virtual void setXSL (
   InputSource* isrc_ptr)
throw (XslException) = 0;
Parameter Description
