Interface Nestable  

All Known Implementing Classes:

NestableException, NestableRuntimeException

---

public interface Nestable

An interface to be implemented by java.lang.Throwable extensions which would like to be able to nest root exceptions inside themselves.

Since:

1.0

Version:

$Id: Nestable.java 4782 2004-11-21 00:11:27Z pgmjsd $

Method Summary
java.lang.Throwable	getCause()           Returns the reference to the exception or error that caused the exception implementing the Nestable to be thrown.
java.lang.String	getMessage()           Returns the error message of this and any nested Throwable.
java.lang.String	getMessage(int index)           Returns the error message of the Throwable in the chain of Throwables at the specified index, numbererd from 0.
java.lang.String[]	getMessages()           Returns the error message of this and any nested Throwables in an array of Strings, one element for each message.
java.lang.Throwable	getThrowable(int index)           Returns the Throwable in the chain of Throwables at the specified index, numbererd from 0.
int	getThrowableCount()           Returns the number of nested Throwables represented by this Nestable, including this Nestable.
java.lang.Throwable[]	getThrowables()           Returns this Nestable and any nested Throwables in an array of Throwables, one element for each Throwable.
int	indexOfThrowable(java.lang.Class type)           Returns the index, numbered from 0, of the first occurrence of the specified type in the chain of Throwables, or -1 if the specified type is not found in the chain.
int	indexOfThrowable(java.lang.Class type, int fromIndex)           Returns the index, numbered from 0, of the first Throwable that matches the specified type in the chain of Throwables with an index greater than or equal to the specified index, or -1 if the type is not found.
void	printPartialStackTrace(java.io.PrintWriter out)           Prints the stack trace for this exception only--root cause not included--using the provided writer.
void	printStackTrace(java.io.PrintStream out)           Prints the stack trace of this exception to the specified print stream.

Method Detail

getCause

public java.lang.Throwable getCause()

Returns the reference to the exception or error that caused the exception implementing the Nestable to be thrown.

---

getMessage

public java.lang.String getMessage()

Returns the error message of this and any nested Throwable.

---

getMessage

public java.lang.String getMessage(int index)

Returns the error message of the Throwable in the chain of Throwables at the specified index, numbererd from 0.

---

getMessages

public java.lang.String[] getMessages()

Returns the error message of this and any nested Throwables in an array of Strings, one element for each message. Any Throwable not containing a message is represented in the array by a null. This has the effect of cause the length of the returned array to be equal to the result of the getThrowableCount() 55 operation.

---

getThrowable

public java.lang.Throwable getThrowable(int index)

Returns the Throwable in the chain of Throwables at the specified index, numbererd from 0.

---

getThrowableCount

public int getThrowableCount()

Returns the number of nested Throwables represented by this Nestable, including this Nestable.

---

getThrowables

public java.lang.Throwable[] getThrowables()

Returns this Nestable and any nested Throwables in an array of Throwables, one element for each Throwable.

---

indexOfThrowable

public int indexOfThrowable(java.lang.Class type)

Returns the index, numbered from 0, of the first occurrence of the specified type in the chain of Throwables, or -1 if the specified type is not found in the chain.

---

indexOfThrowable

public int indexOfThrowable(java.lang.Class type,
                            int fromIndex)

Returns the index, numbered from 0, of the first Throwable that matches the specified type in the chain of Throwables with an index greater than or equal to the specified index, or -1 if the type is not found.

---

printStackTrace

public void printStackTrace(java.io.PrintWriter out)

Prints the stack trace of this exception to the specified print writer. Includes information from the exception, if any, which caused this exception.

---

printStackTrace

public void printStackTrace(java.io.PrintStream out)

Prints the stack trace of this exception to the specified print stream. Includes inforamation from the exception, if any, which caused this exception.

---

printPartialStackTrace

public void printPartialStackTrace(java.io.PrintWriter out)

Prints the stack trace for this exception only--root cause not included--using the provided writer. Used by org.apache.commons.lang.exception.NestableDelegate to write individual stack traces to a buffer. The implementation of this method should call super.printStackTrace(out); in most cases.
