IDENTITY_COMPARISONS

public static final ConcurrentReferenceHashMap.Option IDENTITY_COMPARISONS

Indicates that referential-equality (== instead of .equals()) should be used when locating keys. This offers similar behavior to IdentityHashMap

Method Details

values

public static ConcurrentReferenceHashMap.Option[] 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 ConcurrentReferenceHashMap.Option 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
