DOMErrorHandler

  • DOMErrorHandler is a callback interface used by the DOM to report errors during XML processing or validation.

  • Applications using the DOM are expected to implement this interface to handle errors.

  • The handleError method is called when an error occurs, allowing the application to decide whether to halt or continue processing.

  • Returning false from handleError signals the DOM to stop processing, while true may allow it to continue based on the error's severity.
public interface DOMErrorHandler

DOMErrorHandler is a callback interface that the DOM implementation can call when reporting errors that happens while processing XML data, or when doing some other processing (e.g. validating a document). A DOMErrorHandler object can be attached to a Document using the "error-handler" on the DOMConfiguration interface. If more than one error needs to be reported during an operation, the sequence and numbers of the errors passed to the error handler are implementation dependent.

The application that is using the DOM implementation is expected to implement this interface.

Public Method Summary

abstract boolean
handleError(DOMError error)
This method is called on the error handler when an error occurs.

Public Methods

public abstract boolean handleError (DOMError error)

This method is called on the error handler when an error occurs.
If an exception is thrown from this method, it is considered to be equivalent of returning true.

Parameters
error The error object that describes the error. This object may be reused by the DOM implementation across multiple calls to the handleError method.
Returns
  • If the handleError method returns false, the DOM implementation should stop the current processing when possible. If the method returns true, the processing may continue depending on DOMError.severity.
