ErrorListener

public interface ErrorListener

To provide customized error handling, implement this interface and use the setErrorListener method to register an instance of the implementation with the Transformer. The Transformer then reports all errors and warnings through this interface.

If an application does not register its own custom ErrorListener, the default ErrorListener is used which reports all warnings and errors to System.err and does not throw any Exceptions. Applications are strongly encouraged to register and use ErrorListeners that insure proper behavior for warnings and errors.

For transformation errors, a Transformer must use this interface instead of throwing an Exception: it is up to the application to decide whether to throw an Exception for different types of errors and warnings. Note however that the Transformer is not required to continue with the transformation after a call to fatalError(TransformerException).

Transformers may use this mechanism to report XML parsing errors as well as transformation errors.

Public Method Summary

abstract void
error(TransformerException exception)
Receive notification of a recoverable error.
abstract void
fatalError(TransformerException exception)

Receive notification of a non-recoverable error.

abstract void
warning(TransformerException exception)
Receive notification of a warning.

Public Methods

public abstract void error (TransformerException exception)

Receive notification of a recoverable error.

The transformer must continue to try and provide normal transformation after invoking this method. It should still be possible for the application to process the document through to the end if no other errors are encountered.

Parameters
exception The error information encapsulated in a transformer exception.
Throws
TransformerException if the application chooses to discontinue the transformation.

public abstract void fatalError (TransformerException exception)

Receive notification of a non-recoverable error.

The Transformer must continue to try and provide normal transformation after invoking this met
