Package com.sun.tools.xjc

Class ErrorReceiver

java.lang.Object

com.sun.tools.xjc.ErrorReceiver

All Implemented Interfaces:

ErrorListener, com.sun.xml.bind.api.ErrorListener, ErrorHandler

Direct Known Subclasses:

ConsoleErrorReporter, ErrorReceiverFilter, SchemaCompilerImpl

public abstract class ErrorReceiver
extends Object
implements ErrorHandler, ErrorListener

Implemented by the driver of the compiler engine to handle errors found during the compiliation.

This class implements ErrorHandler so it can be passed to anywhere where ErrorHandler is expected.

However, to make the error handling easy (and make it work with visitor patterns nicely), none of the methods on thi class throws SAXException. Instead, when the compilation needs to be aborted, it throws AbortException, which is unchecked.

This also implements the externally visible ErrorListener so that we can reuse our internal implementation for testing and such.
