Method Detail

values

public static ThreadLocalContextStorage[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ThreadLocalContextStorage c : ThreadLocalContextStorage.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ThreadLocalContextStorage valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

attach

public Scope attach(Context toAttach)

Description copied from interface: ContextStorage

Sets the specified Context as the current Context and returns a Scope representing the scope of execution. Scope.close() must be called when the current Context should be restored to what it was before attaching toAttach.

Specified by:

attach in interface ContextStorage

current

@Nullable
public Context current()

Description copied from interface: ContextStorage

Returns the current Context. If no Context has been attached yet, this will return null.

Specified by:
