public interface Nestable
An interface to be implemented by Throwable
extensions which would like to be able to nest root exceptions
inside themselves.
| Method Summary | |
|---|---|
Throwable |
getCause()
Returns the reference to the exception or error that caused the exception implementing the Nestable to be thrown. |
String |
getMessage()
Returns the error message of this and any nested Throwable. |
String |
getMessage(int index)
Returns the error message of the Throwable in the chain
of Throwables at the specified index, numbererd from 0. |
String[] |
getMessages()
Returns the error message of this and any nested Throwables
in an array of Strings, one element for each message. |
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. |
Throwable[] |
getThrowables()
Returns this Nestable and any nested Throwables
in an array of Throwables, one element for each
Throwable. |
int |
indexOfThrowable(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(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(PrintWriter out)
Prints the stack trace for this exception only--root cause not included--using the provided writer. |
void |
printStackTrace(PrintStream out)
Prints the stack trace of this exception to the specified print stream. |
void |
printStackTrace(PrintWriter out)
Prints the stack trace of this exception to the specified print writer. |
| Method Detail |
|---|
Throwable getCause()
Nestable to be thrown.
String getMessage()
Throwable.
String getMessage(int index)
Throwable in the chain
of Throwables at the specified index, numbererd from 0.
index - the index of the Throwable in the chain of
Throwables
Throwable at the
specified index in the chain does not contain a message
IndexOutOfBoundsException - if the index argument is
negative or not less than the count of Throwables in the
chainString[] getMessages()
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()
operation.
Throwable getThrowable(int index)
Throwable in the chain of
Throwables at the specified index, numbererd from 0.
index - the index, numbered from 0, of the Throwable in
the chain of Throwables
Throwable
IndexOutOfBoundsException - if the index argument is
negative or not less than the count of Throwables in the
chainint getThrowableCount()
Throwables represented by
this Nestable, including this Nestable.
Throwable[] getThrowables()
Nestable and any nested Throwables
in an array of Throwables, one element for each
Throwable.
Throwablesint indexOfThrowable(Class type)
Throwables, or -1 if the
specified type is not found in the chain.
type - Class to be found
int indexOfThrowable(Class type,
int fromIndex)
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.
type - Class to be foundfromIndex - the index, numbered from 0, of the starting position in
the chain to be searched
IndexOutOfBoundsException - if the fromIndex argument
is negative or not less than the count of Throwables in the
chainvoid printStackTrace(PrintWriter out)
out - PrintWriter to use for output.void printStackTrace(PrintStream out)
out - PrintStream to use for output.void printPartialStackTrace(PrintWriter out)
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.
out - The writer to use.
