public abstract class NestedRuntimeException
extends java.lang.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!).

Constructor Detail

NestedRuntimeException

public NestedRuntimeException(java.lang.String msg)

Construct a NestedRuntimeException with the specified detail message.

Parameters:

msg - the detail message

NestedRuntimeException

public NestedRuntimeException(java.lang.String msg,
                      java.lang.Throwable cause)

Construct a NestedRuntimeException with the specified detail message and nested exception.

Parameters:

msg - the detail message

cause - the nested exception

Method Detail

getMessage

public java.lang.String getMessage()

Return the detail message, including the message from the nested exception if there is one.

Overrides:

getMessage in class java.lang.Throwable

getRootCause

public java.lang.Throwable getRootCause()

Retrieve the innermost cause of this exception, if any.

Returns:

the innermost exception, or null if none

getMostSpecificCause

public java.lang.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.

Returns:

the most specific cause (never null)

contains

public boolean contains(java.lang.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.

Parameters:

exType - the exception type to look for

Returns:

whether there is a nested exception of the specified type
