Enum Constant Details

UNSHARED

public static final ContextStrategy UNSHARED

Creates an unshared context, where state is always "absent".

invalid reference

Context#computeIfAbsent(Object, Function)

will always creates its value from the specified factory. Intended for use when some other mechanism already ensures mutually exclusive access to the requested state.

SHARED

public static final ContextStrategy SHARED

Creates a context storing sharable references. Concurrent

invalid reference

Context#computeIfAbsent(Object, Function)

invocations for the same key will reference the same state, until all references are closed.

Method Details

values

public static ContextStrategy[] values()

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

Returns:

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

valueOf

public static ContextStrategy valueOf(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:

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

NullPointerException - if the argument is null
