Interface Summary
Interface | Description
--- | ---
ErrorListener | To provide customized error handling, implement this interface and use the `setErrorListener` method to register an instance of the implmentation with the `Transformer`.
Result | An object that implements this interface contains the information needed to build a transformation result tree.
Source | An object that implements this interface contains the information needed to act as source input (XML source or transformation instructions).
SourceLocator | This interface is primarily for the purposes of reporting where an error occurred in the XML source or transformation instructions.
Templates | An object that implements this interface is the runtime representation of processed transformation instructions.
URIResolver | An object that implements this interface that can be called by the processor to turn a URI used in document(), xsl:import, or xsl:include into a Source object.
