public abstract class NestedRuntimeException
extends RuntimeException

Handy class for wrapping runtime Exceptions with a root cause.

This class is abstract to force the programmer to extend the class. getMessage will include nested exception information; printStackTrace and other like methods will delegate to the wrapped exception, if any.

The similarity between this class and the NestedCheckedException class is unavoidable, as Java forces these two classes to have different superclasses (ah, the inflexibility of concrete inheritance!).

getMessage 在类中 Throwable

getRootCause

public Throwable getRootCause()

Retrieve the innermost cause of this exception, if any.

返回:

the innermost exception, or null if none

从以下版本开始:

2.0

getMostSpecificCause

public Throwable getMostSpecificCause()

Retrieve the most specific cause of this exception, that is, either the innermost cause (root cause) or this exception itself.

Differs from getRootCause() in that it falls back to the present exception if there is no root cause.

返回:

the most specific cause (never null)

从以下版本开始:

2.0.3

contains

public boolean contains(Class<?> exType)

Check whether this exception contains an exception of the given type: either it is of the given class itself or it contains a nested cause of the given type.

参数:

exType - the exception type to look for

返回:

whether there is a nested exception of the specified type
