Direct Known Subclasses:

LightestTransformer

public abstract class CustomizedTransformer
extends Object
implements groovy.lang.GroovyObject

Applies an XSL transform, with customizations. This is a facade encapsulating the basic javax.xml.transform.Transformer functionality. The customize() method is called at most once, after which the customized stylesheet is cached inside the internal transformer variable. This implementation is NOT thread-safe.

Method Detail

getTransformAsStream

public abstract InputStream getTransformAsStream()

Returns the XSL transform source as an InputStream.

setParameter

public void setParameter(String name,
                         Object value)

Adds a parameter for the transformation.

Parameters:

name -

value -

transform

public void transform(String s,
                      OutputStream os)

Transforms the given XML string with customizations, and writes the result to the given output stream. This version calls the version of transform() that taks an InputStream as its first parameter.

Parameters:

s - the XML string to transform. Assumed to be UTF-8 encoded.

transform

public void transform(InputStream is,
                      OutputStream os)

Parameters:

is -

os -

customize

public abstract void customize(Document doc)

Customizes the XSL transform XML. This will be invoked before the transform is applied to the source document.

Parameters:

doc - the document object of the XSLT document.
