public final class NullErrorHandler
extends Object
implements ErrorHandler

This implementation for a XML Error handler swallows the error messages. The methods

• error()
• fatalError()
• warning()

have an empty body.

This error handler is useful when really no internal error handling is desired; calling DocumentBuilder.setErrorHandler(ErrorHandler) with null as argument will activate a built-in error handler with an unpredictable behaviour.

The one and only instance for this class can be obtained using the INSTANCE constant.

This simple initialisation pattern was chosen instead of a full Singleton setup because the error handler does not maintain a state.
