Constructor Detail

JDOException

public JDOException()

Constructs a new JDOException without a detail message.

JDOException

public JDOException(String msg)

Constructs a new JDOException with the specified detail message.

Parameters:

msg - the detail message.

JDOException

public JDOException(String msg,
                    Throwable[] nested)

Constructs a new JDOException with the specified detail message and nested Throwables.

Parameters:

msg - the detail message.

nested - the nested Throwable[].

JDOException

public JDOException(String msg,
                    Throwable nested)

Constructs a new JDOException with the specified detail message and nested Throwable.

Parameters:

msg - the detail message.

nested - the nested Throwable.

JDOException

public JDOException(String msg,
                    Object failed)

Constructs a new JDOException with the specified detail message and failed object.

Parameters:

msg - the detail message.

failed - the failed object.

JDOException

public JDOException(String msg,
                    Throwable[] nested,
                    Object failed)

Constructs a new JDOException with the specified detail message, nested Throwables, and failed object.

Parameters:

msg - the detail message.

nested - the nested Throwable[].

failed - the failed object.

JDOException

public JDOException(String msg,
                    Throwable nested,
                    Object failed)

Constructs a new JDOException with the specified detail message, nested Throwable, and failed object.

Parameters:

msg - the detail message.

nested - the nested Throwable.

failed - the failed object.

Method Detail

getFailedObject

public Object getFailedObject()

The exception may include a failed object.

Returns:

the failed object.

getNestedExceptions

public Throwable[] getNestedExceptions()

The exception may have been caused by multiple exceptions in the runtime. If multiple objects caused the problem, each failed object will have its own Exception.

Returns:

the nested Throwable array.

getCause

public Throwable getCause()

Often there is only one nested exception, and this method returns it. If there are more than one, then this method returns the first nested exception. If there is no nested exception, then null is returned.

Overrides:

getCause in class Throwable

Returns:

the first or only nested Throwable.

Since:

1.0.1

initCause

public Throwable initCause(Throwable cause)

JDK 1.4 includes a new chaining mechanism for Throwable, but since JDO has its own "legacy" chaining mechanism, the "standard" mechanism cannot be used. This method always throws a JDOFatalInternalException.

Overrides:

initCause in class Throwable

Parameters:

cause - ignored.

Returns:

never.

toString

public String toString()

The String representation includes the name of the class, the descriptive comment (if any), the String representation of the failed Object (if any), and the String representation of the nested Throwables (if any).

Overrides:

toString in class Throwable

Returns:

the String.

printStackTrace

public void printStackTrace()

Prints this JDOException and its backtrace to the standard error output. Print nested Throwables' stack trace as well.

Overrides:

printStackTrace in class Throwable

printStackTrace

public void printStackTrace(PrintStream s)

Prints this JDOException and its backtrace to the specified print stream. Print nested Throwables' stack trace as well.

Overrides:

printStackTrace in class Throwable

Parameters:

s - PrintStream to use for output

printStackTrace

public void printStackTrace(PrintWriter s)

Prints this JDOException and its backtrace to the specified print writer. Print nested Throwables' stack trace as well.

Overrides:

printStackTrace in class Throwable

Parameters:

s - PrintWriter to use for output
