Method Details

clearParameters

public abstract void clearParameters()
Clears all parameter values.

getErrorListener

public abstract ErrorListener getErrorListener()
Returns the callback used to report errors during the transformation.

getOutputProperties

public abstract Properties getOutputProperties()
Returns a copy of the output properties for the transformation. Missing properties are defaulted according the XSLT Recommendation, section 16: getProperty(String) returns all properties including defaulted ones, and get(Object) returns only the properties explicitly set in the stylesheet.

getOutputProperty

public abstract String getOutputProperty(String name)
            throws IllegalArgumentException
Returns the value of an output property for the transformation. Only explicit properties set programmatically or defined in the stylesheet, not defaulted properties, are returned by this method.
Parameters:
name - the property name (an XML Name, or a namespace-prefixed XML Name of the form {namespaceURI}localName

getParameter

public abstract Object getParameter(String name)
Returns the specified parameter value.
Parameters:
name - the parameter name (an XML Name, or a namespace-prefixed XML Name of the form {namespaceURI}localName

getURIResolver

public abstract URIResolver getURIResolver()
Returns the callback used to resolve entities referenced by xsl:include, xsl:import, or the XPath document() function.

reset

public void reset()
Reset this Transformer to its original configuration.
Since:
1.3

setErrorListener

public abstract void setErrorListener(ErrorListener listener)
            throws IllegalArgumentException
Sets the callback used to report errors during the transformation.

setOutputProperties

public abstract void setOutputProperties(Properties oformat)
            throws IllegalArgumentException
Sets the output properties for the transformation, overriding any properties defined in the stylesheet. The format of property keys is as in the setOutputProperty(java.lang.String,java.lang.String) method.
Parameters:
oformat - a set of output properties, or null to reset all the properties to their default values

setOutputProperty

public abstract void setOutputProperty(String name,
                                       String value)
            throws IllegalArgumentException
Sets an output property for the transformation, overriding any property of the same name defined in the stylesheet.
Parameters:
name - the property name (an XML Name, or a namespace-prefixed XML Name of the form {namespaceURI}localName
value - the string value of the property

setParameter

public abstract void setParameter(String name,
                                  Object value)
Sets a parameter value for the transformation. Parameters may be referenced in the XSLT stylesheet.
Parameters:
name - the parameter name (an XML Name, or a namespace-prefixed XML Name of the form {namespaceURI}localName
value - the value to assign

setURIResolver

public abstract void setURIResolver(URIResolver resolver)
Sets the callback used to resolve entities referenced by xsl:include, xsl:import, or the XPath document() function.

transform

public abstract void transform(Source xmlSource,
                               Result outputTarget)
            throws TransformerException
Transforms the source XML to a result tree.
Parameters:
xmlSource - the XML source
outputTarget - the result of the transformation
