ErrorListener

interface ErrorListener
javax.xml.transform.ErrorListener

To provide customized error handling, implement this interface and use the setErrorListener method to register an instance of the implementation with the javax.xml.transform.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(javax.xml.transform.TransformerException).

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

Public methods

error

Added in API level 8
abstract fun error(exception: TransformerException!): Unit

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 TransformerException!: The error information encapsulated in a transformer exception.
Exceptions
javax.xml.transform.TransformerException if the application chooses to discontinue the transformation.

fatalError

Added in API level 8
abstract fun fatalError(exception: TransformerException!): Unit

Receive notification of a non-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, but there is no guarantee that the output will be useable.

Parameters
exception TransformerException!: The error information encapsulated in a TransformerException.
Exceptions
javax.xml.transform.TransformerException if the application chooses to discontinue the transformation.

warning

Added in API level 8
abstract fun warning(exception: TransformerException!): Unit

Receive notification of a warning.

javax.xml.transform.Transformer can use this method to report conditions that are not errors or fatal errors. The default behavior is to take no action.

After invoking this method, the Transformer must continue with the transformation. It should still be possible for the application to process the document through to the end.

Parameters
exception TransformerException!: The warning information encapsulated in a transformer exception.
Exceptions
javax.xml.transform.TransformerException if the application chooses to discontinue the transformation.
