方法详细资料

rethrowIfUnrecoverable

public static void rethrowIfUnrecoverable(Throwable exception)

Rethrow the supplied exception if it is unrecoverable.

If the supplied exception is not unrecoverable, this method does nothing.

throwAsUncheckedException

public static RuntimeException throwAsUncheckedException(Throwable t)

Throw the supplied Throwable, masked as an unchecked exception.

The supplied Throwable will not be wrapped. Rather, it will be thrown as is using an exploit of the Java language that relies on a combination of generics and type erasure to trick the Java compiler into believing that the thrown exception is an unchecked exception even if it is a checked exception.

Warning

This method should be used sparingly.

参数:

t - the Throwable to throw as an unchecked exception; never null

返回:

this method always throws an exception and therefore never returns anything; the return type is merely present to allow this method to be supplied as the operand in a throw statement

throwAs

public static <T extends Throwable> void throwAs(Throwable t)
                                          throws T extends Throwable

Rethrows t (identical object).

抛出:

T extends Throwable
