### DOMErrorHandlerWrapper

    public DOMErrorHandlerWrapper(org.apache.xerces.dom3.DOMErrorHandler domErrorHandler)

Method Detail

### setErrorHandler

    public void setErrorHandler(org.apache.xerces.dom3.DOMErrorHandler errorHandler)

  Sets the DOM error handler.

### getErrorHandler

    public org.apache.xerces.dom3.DOMErrorHandler getErrorHandler()

### warning

    public void warning(java.lang.String domain,
                        java.lang.String key,
                        org.apache.xerces.xni.parser.XMLParseException exception)
                 throws org.apache.xerces.xni.XNIException

  Reports a warning. Warnings are non-fatal and can be safely ignored by most applications.
  Specified by:
    `warning` in interface `org.apache.xerces.xni.parser.XMLErrorHandler`
  Parameters:
    `domain` - The domain of the warning. The domain can be any string but is suggested to be a valid URI. The domain can be used to conveniently specify a web site location of the relevent specification or document pertaining to this warning.
    `key` - The warning key. This key can be any string and is implementation dependent.
    `exception` - Exception.
  Throws:
    `org.apache.xerces.xni.XNIException` - Thrown to signal that the parser should stop parsing the document.

### error

    public void error(java.lang.String domain,
                      java.lang.String key,
                      org.apache.xerces.xni.parser.XMLParseException exception)
               throws org.apache.xerces.xni.XNIException

  Reports an error. Errors are non-fatal and usually signify that the document is invalid with respect to its grammar(s).
  Specified by:
    `error` in interface `org.apache.xerces.xni.parser.XMLErrorHandler`
  Parameters:
    `domain` - The domain of the error. The domain can be any string but is suggested to be a valid URI. The domain can be used to conveniently specify a web site location of the relevent specification or document pertaining to this error.
    `key` - The error key. This key can be any string and is implementation dependent.
    `exception` - Exception.
  Throws:
    `org.apache.xerces.xni.XNIException` - Thrown to signal that the parser should stop parsing the document.

### fatalError

    public void fatalError(java.lang.String domain,
                           java.lang.String key,
                           org.apache.xerces.xni.parser.XMLParseException exception)
                    throws org.apache.xerces.xni.XNIException

  Report a fatal error. Fatal errors usually occur when the document is not well-formed and signifies that the parser cannot continue normal operation.

  Note: The error handler should always throw an `XNIException` from this method. This exception can either be the same exception that is passed as a parameter to the method or a new XNI exception object. If the registered error handler fails to throw an exception, the continuing operation of the parser is undetermined.

  Specified by:
    `fatalError` in interface `org.apache.xerces.xni.parser.XMLErrorHandler`
  Parameters:
    `domain` - The domain of the fatal error. The domain can be any string but is suggested to be a valid URI. The domain can be used to conveniently specify a web site location of the relevent specification or document pertaining to this fatal error.
    `key` - The fatal error key. This key can be any string and is implementation dependent.
    `exception` - Exception.
  Throws:
    `org.apache.xerces.xni.XNIException` - Thrown to signal that the parser should stop parsing the document.

### handleError

    public boolean handleError(org.apache.xerces.dom3.DOMError error)

  Description copied from interface: `org.apache.xerces.dom3.DOMErrorHandler`
  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`.
  Specified by:
    `handleError` in interface `org.apache.xerces.dom3.DOMErrorHandler`
  Following copied from interface: `org.apache.xerces.dom3.DOMErrorHandler`
  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`.
