PrivilegedExceptionAction (Java Platform SE 8 ) (original) (raw)

public interface PrivilegedExceptionAction
A computation to be performed with privileges enabled, that throws one or more checked exceptions. The computation is performed by invokingAccessController.doPrivileged on thePrivilegedExceptionAction object. This interface is used only for computations that throw checked exceptions; computations that do not throw checked exceptions should use PrivilegedAction instead.

     * #### run

     Performs the computation. This method will be called by`AccessController.doPrivileged` after enabling privileges.  
     Returns:  
     a class-dependent value that may represent the results of the computation. Each class that implements`PrivilegedExceptionAction` should document what (if anything) this value represents.  
     Throws:  
     `[Exception](../../java/lang/Exception.html "class in java.lang")` \- an exceptional condition has occurred. Each class that implements `PrivilegedExceptionAction` should document the exceptions that its run method can throw.
