protected NestableDelegate delegate
The helper instance which contains much of the code which we
delegate to.
NestableRuntimeException
public NestableRuntimeException()
Constructs a new NestableRuntimeException
without specified
detail message.
NestableRuntimeException
public NestableRuntimeException(String msg)
Constructs a new NestableRuntimeException
with specified
detail message.
NestableRuntimeException
public NestableRuntimeException(String msg,
Throwable cause)
Constructs a new NestableRuntimeException
with specified
detail message and nested Throwable
.
msg
- the error messagecause
- the exception or error that caused this exception to be
thrown
NestableRuntimeException
public NestableRuntimeException(Throwable cause)
Constructs a new NestableRuntimeException
with specified
nested Throwable
.
cause
- the exception or error that caused this exception to be
thrown
getCause
public Throwable getCause()
Returns the reference to the exception or error that caused the
exception implementing the Nestable
to be thrown.
- getCause in interface Nestable
- throwable that caused the original exception
getMessage
public String getMessage()
Returns the detail message string of this throwable. If it was
created with a null message, returns the following:
(cause==null ? null : cause.toString()).
- getMessage in interface Nestable
- String message string of the throwable
getMessage
public String getMessage(int index)
Returns the error message of the Throwable
in the chain
of Throwable
s at the specified index, numbered from 0.
- getMessage in interface Nestable
index
- the index of the Throwable
in the chain of
Throwable
s
- the error message, or null if the
Throwable
at the
specified index in the chain does not contain a message
getMessages
public String[] getMessages()
Returns the error message of this and any nested
Throwable
s
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
Nestable.getThrowableCount()
operation.
- getMessages in interface Nestable
getThrowable
public Throwable getThrowable(int index)
Returns the Throwable
in the chain of
Throwable
s at the specified index, numbered from 0.
- getThrowable in interface Nestable
index
- the index, numbered from 0, of the Throwable
in
the chain of Throwable
s
getThrowableCount
public int getThrowableCount()
Returns the number of nested Throwable
s represented by
this Nestable
, including this Nestable
.
- getThrowableCount in interface Nestable
getThrowables
public Throwable[] getThrowables()
Returns this Nestable
and any nested Throwable
s
in an array of Throwable
s, one element for each
Throwable
.
- getThrowables in interface Nestable
indexOfThrowable
public int indexOfThrowable(Class type)
Returns the index, numbered from 0, of the first occurrence of the
specified type, or a subclass, in the chain of
Throwable
s.
The method returns -1 if the specified type is not found in the chain.
NOTE: From v2.1, we have clarified the
Nestable
interface
such that this method matches subclasses.
If you want to NOT match subclasses, please use
ExceptionUtils.indexOfThrowable(Throwable,Class)
(which is avaiable in all versions of lang).
- indexOfThrowable in interface Nestable
type
- the type to find, subclasses match, null returns -1
- index of the first occurrence of the type in the chain, or -1 if
the type is not found
indexOfThrowable
public int indexOfThrowable(Class type,
int fromIndex)
Returns the index, numbered from 0, of the first
Throwable
that matches the specified type, or a subclass, in the chain of
Throwable
s
with an index greater than or equal to the specified index.
The method returns -1 if the specified type is not found in the chain.
NOTE: From v2.1, we have clarified the
Nestable
interface
such that this method matches subclasses.
If you want to NOT match subclasses, please use
ExceptionUtils.indexOfThrowable(Throwable,Class,int)
(which is avaiable in all versions of lang).
- indexOfThrowable in interface Nestable
type
- the type to find, subclasses match, null returns -1fromIndex
- the index, numbered from 0, of the starting position in
the chain to be searched
- index of the first occurrence of the type in the chain, or -1 if
the type is not found
printPartialStackTrace
public final void printPartialStackTrace(PrintWriter out)
Prints the stack trace for this exception only--root cause not
included--using the provided writer. Used by
NestableDelegate
to write
individual stack traces to a buffer. The implementation of
this method should call
super.printStackTrace(out);
in most cases.
- printPartialStackTrace in interface Nestable
printStackTrace
public void printStackTrace()
printStackTrace
public void printStackTrace(PrintStream out)
Prints the stack trace of this exception to the specified print
stream. Includes information from the exception, if any,
which caused this exception.
- printStackTrace in interface Nestable
out
- PrintStream
to use for output.
printStackTrace
public void printStackTrace(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 in interface Nestable
