Class org.xmlmiddleware.xmldbms.actions.ActionCompiler

java.lang.Object

public class ActionCompiler

extends Object

implements ContentHandler

Action documents specify a default action for a document, as well as per-class (per element type) actions. For more information, see actions.dtd.

ActionCompiler assumes that the action document is valid. If it is not, the class will either generate garbage or throw an exception. One way to guarantee that the document is valid is to pass a validating parser to the action compiler.

For example, the following code creates an Actions object from the sales.act action document.

    // Instantiate a new action compiler and set the XMLReader.
    compiler = new ActionCompiler(xmlReader);

    

    // Compile sales.act into an Actions object.
    actions = compiler.compile(map, new InputSource(new FileReader("sales.act")));
