public class XMLException
extends RuntimeException

The generic superclass for most runtime exceptions thrown in `nu.xom`. The general principle followed is that anything that can normally be detected by testing such as using spaces in an element name is a runtime exception. Exceptions that depend on environmental conditions, such as might occur when parsing an external file, are checked exceptions, because these depend on variable input, and thus all problems may not be detected during testing.

Constructor Detail

### XMLException

    public XMLException(String message,
                        Throwable cause)

  Creates a new `XMLException` with the specified detail message and an underlying root cause.

Parameters:
  `message` - information about the cause of the exception
  `cause` - the nested exception that caused this exception

### XMLException

    public XMLException(String message)

  Creates a new `XMLException` with the specified detail message.

Parameters:
  `message` - information about the cause of the exception

Method Detail

### getCause

    public Throwable getCause()

  Return the original cause that led to this exception, or null if there was no original exception.

  Returns:
    the root cause of this exception

### initCause

    public Throwable initCause(Throwable cause)

  Sets the root cause of this exception. This may only be called once. Subsequent calls throw an `IllegalStateException`.

  This method is unnecessary in Java 1.4 where it could easily be inherited from the superclass. However, including it here allows this method to be used in Java 1.3 and earlier.

  Parameters:
    `cause` - the root cause of this exception
  Returns:
    this `XMLException`
  Throws:
    `IllegalArgumentException` - if the cause is this exception (An exception cannot be its own cause.)
    `IllegalStateException` - if this method is called twice
