      • 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,
                            javax.xml.transform.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,
                            javax.xml.transform.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 javax.xml.transform.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​(javax.xml.transform.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.)
        Overrides:
        getCause in class java.lang.Throwable
      • 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.

        Overrides:
        initCause in class java.lang.Throwable
        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.
