Constructor Detail

### DTMException

    public DTMException(java.lang.String message)

  Create a new DTMException.
  Parameters:
    `message` - The error or warning message.

### DTMException

    public DTMException(java.lang.Throwable e)

  Create a new DTMException wrapping an existing exception.
  Parameters:
    `e` - The exception to be wrapped.

### DTMException

    public DTMException(java.lang.String message,
                        java.lang.Throwable e)

  Wrap an existing exception in a DTMException.

  This is used for throwing processor exceptions before the processing has started.

  Parameters:
    `message` - The error or warning message, or null to use the message from the embedded exception.
    `e` - Any exception

### DTMException

    public DTMException(java.lang.String message,
                        SourceLocator locator)

  Create a new DTMException from a message and a Locator.

  This constructor is especially useful when an application is creating its own exception from within a DocumentHandler callback.

  Parameters:
    `message` - The error or warning message.
    `locator` - The locator object for the error or warning.

### DTMException

    public DTMException(java.lang.String message,
                        SourceLocator locator,
                        java.lang.Throwable e)

  Wrap an existing exception in a DTMException.
  Parameters:
    `message` - The error or warning message, or null to use the message from the embedded exception.
    `locator` - The locator object for the error or warning.
    `e` - Any exception

Method Detail

### getLocator

    public SourceLocator getLocator()

  Method getLocator retrieves an instance of a SourceLocator object that specifies where an error occured.
  Returns:
    A SourceLocator object, or null if none was specified.

### setLocator

    public void setLocator(SourceLocator location)

  Method setLocator sets an instance of a SourceLocator object that specifies where an error occured.
  Parameters:
    `location` - A SourceLocator object, or null to clear the location.

### getException

    public java.lang.Throwable getException()

  This method retrieves an exception that this exception wraps.
  Returns:
    An Throwable object, or null.
  See Also:
    `getCause()`

### getCause

    public java.lang.Throwable getCause()

  Returns the cause of this throwable or `null` if the cause is nonexistent or unknown. (The cause is the throwable that caused this throwable to get thrown.)

### initCause

    public java.lang.Throwable initCause(java.lang.Throwable cause)

  Initializes the cause of this throwable to the specified value. (The cause is the throwable that caused this throwable to get thrown.)

  This method can be called at most once. It is generally called from within the constructor, or immediately after creating the throwable. If this throwable was created with `DTMException(Throwable)` or `DTMException(String,Throwable)`, this method cannot be called even once.

  Parameters:
    `cause` - the cause (which is saved for later retrieval by the `getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)
  Returns:
    a reference to this `Throwable` instance.
  Throws:
    java.lang.IllegalArgumentException - if `cause` is this throwable. (A throwable cannot be its own cause.)
    java.lang.IllegalStateException - if this throwable was created with `DTMException(Throwable)` or `DTMException(String,Throwable)`, or this method has already been called on this throwable.

### getMessageAndLocation

    public java.lang.String getMessageAndLocation()

  Get the error message with location information appended.

### getLocationAsString

    public java.lang.String getLocationAsString()

  Get the location information as a string.
  Returns:
    A string with location info, or null if there is no location information.

### printStackTrace

    public void printStackTrace()

  Print the the trace of methods from where the error originated. This will trace all nested exception objects, as well as this object.
  Overrides:
    printStackTrace in class java.lang.Throwable

### printStackTrace

    public void printStackTrace(java.io.PrintStream s)

  Print the the trace of methods from where the error originated. This will trace all nested exception objects, as well as this object.
  Parameters:
    `s` - The stream where the dump will be sent to.
  Overrides:
    printStackTrace in class java.lang.Throwable

### printStackTrace

    public void printStackTrace(java.io.PrintWriter s)

  Print the the trace of methods from where the error originated. This will trace all nested exception objects, as well as this object.
  Parameters:
    `s` - The writer where the dump will be sent to.
  Overrides:
    printStackTrace in class java.lang.Throwable
