Method Detail

doPrivileged

public static <T,E extends Exception> T doPrivileged(ThrowingSupplier<T,E> action)
                                              throws E extends Exception

Performs the specified action with privileges enabled. The action is performed with all of the permissions possessed by this class' (or by the migration framework's) protection domain.

If the action's ThrowingSupplier.get() method throws an unchecked exception, it will propagate through this method.

Note: Any DomainCombiner associated with the current AccessControlContext will be ignored while the action is performed.

Type Parameters:

T - the type of the value returned by the action

E - the type of exceptions thrown by the action

Parameters:

action - the action to be performed

Returns:

the value returned by the action's run method

Throws:

E - if the specified action's threw the exception

IllegalArgumentException - if action is null

E extends Exception

doConditionallyPrivileged

public static <T,E extends Exception> T doConditionallyPrivileged(boolean condition,
                                                                  ThrowingSupplier<T,E> action)
                                                           throws E extends Exception

Performs the specified action with privileges enabled if the specified condition is true . The action is performed with all of the permissions possessed by this class' (or by the migration framework's) protection domain. Otherwise performs the specified action using the caller's permissions.

If the action's ThrowingSupplier.get() method throws an unchecked exception, it will propagate through this method.

Note: Any DomainCombiner associated with the current AccessControlContext will be ignored while the action is performed.

Type Parameters:

T - the type of the value returned by the action

E - the type of exceptions thrown by the action

Parameters:

condition - true to perform the action with the permissions possessed by this class; false to use the caller's permissions

action - the action to be performed

Returns:

the value returned by the action's run method

Throws:

E - if the specified action's threw the exception

IllegalArgumentException - if action is null

E extends Exception

doPrivileged

public static <E extends Exception> void doPrivileged(ThrowingRunnable<E> action)
                                               throws E extends Exception

Performs the specified action with privileges enabled. The action is performed with all of the permissions possessed by this class' (or by the migration framework's) protection domain.

If the action's ThrowingSupplier.get() method throws an unchecked exception, it will propagate through this method.

Note: Any DomainCombiner associated with the current AccessControlContext will be ignored while the action is performed.

Type Parameters:

E - the type of exceptions thrown by the action

Parameters:

action - the action to be performed

Throws:

E - if the specified action's threw the exception

IllegalArgumentException - if action is null

E extends Exception

public static <E extends Exception> void doConditionallyPrivileged(boolean condition,
                                                                   ThrowingRunnable<E> action)

condition - true to perform the action with the permissions possessed by this class; false to use the caller's permissions
