Enum Constant Detail

DEFAULT

public static final Scope DEFAULT
One instance per injection.


SINGLETON

public static final Scope SINGLETON
One instance per container.


THREAD

public static final Scope THREAD
One instance per thread.

Note: if a thread local object strongly references its Container, neither the Container nor the object will be eligible for garbage collection, i.e. memory leak.


REQUEST

public static final Scope REQUEST
One instance per request.


SESSION

public static final Scope SESSION
One instance per session.


WIZARD

public static final Scope WIZARD
One instance per wizard.

Method Detail

values

public static Scope[] 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 (Scope c : Scope.values())
    System.out.println(c);

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

valueOf

public static Scope 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
