Enum Constant Detail

STRICT

public static final RefreshCachedSupplier.StaleValueBehavior STRICT

Strictly treat the stale time. Never return a stale cached value (except when the supplier returns an expired value, in which case the supplier will return the value but only for a very short period of time to prevent overloading the underlying supplier).

ALLOW

public static final RefreshCachedSupplier.StaleValueBehavior ALLOW

Allow stale values to be returned from the cache. Value retrieval will never fail, as long as the cache has succeeded when calling the underlying supplier at least once.

Method Detail

values

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

Returns:

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

valueOf

public static RefreshCachedSupplier.StaleValueBehavior 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
