Class InvocationTargetException

Contents
  • All Implemented Interfaces:
    Serializable

    public class InvocationTargetException
extends ReflectiveOperationException
    InvocationTargetException is a checked exception that wraps an exception thrown by an invoked method or constructor.

    As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "target exception" that is provided at construction time and accessed via the getTargetException() method is now known as the cause, and may be accessed via the Throwable.getCause() method, as well as the aforementioned "legacy method."

    • Method Detail

      • getTargetException

        public Throwable getTargetException()
        Get the thrown target exception.

        This method predates the general-purpose exception chaining facility. The Throwable.getCause() method is now the preferred means of obtaining this information.

        Returns:
        the thrown target exception (cause of this exception).

      • getCause

        public Throwable getCause()
        Returns the cause of this exception (the thrown target exception, which may be null).
        Overrides:
        getCause in class Throwable
        Returns:
        the cause of this exception.
        Since:
        1.4
