An instance of this class can be obtained with the
TransformerFactory.
method. This instance may then be used to process XML from a
variety of sources and write the transformation output to a
variety of sinks.
An object of this class may not be used in multiple threads running concurrently. Different Transformers may be used concurrently by different threads.
A Transformer
may be used multiple times. Parameters and
output properties are preserved across transformations.

The new error listener. listener)Set the error event listener in effect for the transformation. |

A set of output properties that will be
used to override any of the same properties in affect
for the transformation. oformat)Set the output properties for the transformation. |

The name of the parameter, which may begin with a

up to the processor to provide the proper object conversion or to simply
pass the object on for use in an extension. value)Add a parameter for the transformation. |

getOutputProperties | back to summary |
---|---|
public abstract Properties getOutputProperties() Get a copy of the output properties for the transformation. The properties returned should contain properties set by the user,
and properties set by the stylesheet, and these properties
are "defaulted" by default properties specified by
section 16 of the
XSL Transformations (XSLT) W3C Recommendation. The properties that
were specifically set by the user or the stylesheet should be in the base
Properties list, while the XSLT default properties that were not
specifically set should be the default Properties list. Thus,
getOutputProperties().getProperty(String key) will obtain any
property in that was set by Note that mutation of the Properties object returned will not effect the properties that the transformer contains. If any of the argument keys are not recognized and are not
namespace qualified, the property will be ignored and not returned.
In other words the behaviour is not orthogonal with

setOutputProperties | back to summary |

public abstract void setOutputProperties(Properties oformat) Set the output properties for the transformation. These properties will override properties set in the Templates with xsl:output. If argument to this function is null, any properties previously set are removed, and the value will revert to the value defined in the templates object. Pass a qualified property key name as a two-part string, the namespace URI enclosed in curly braces ({}), followed by the local name. If the name has a null URL, the String only contain the local name. An application can safely check for a non-null URI by testing to see if the first character of the name is a '{' character. For example, if a URI and local name were obtained from an element defined with <xyz:foo xmlns:xyz="http://xyz.foo.com/yada/baz.html"/>, then the qualified name would be "{http://xyz.foo.com/yada/baz.html}foo". Note that no prefix is used. AnIllegalArgumentException is thrown if any of the
argument keys are not recognized and are not namespace qualified.

An application can safely check for a non-null URI by testing to see if the first character of the name is a '{' character.
