Enum Constant Summary

Enum Constants

Enum Constant	Description
APPROXIMATE_FAST	Compute an approximate hashCode of the contents of this AnyVersionedMap that may have a large number of hash collisions, but can be calculated without iterating over the full contents.
PRECISE_SLOW	Calculate the hashCode of the contents of this AnyVersionedMap to reduce hash collisions as much as possible, even iterating over the full contents in necessary.

Method Summary

Modifier and Type	Method	Description
static ContentHashCode	valueOf(String name)	Returns the enum constant of this class with the specified name.
static ContentHashCode[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

PRECISE_SLOW

public static final ContentHashCode PRECISE_SLOW

Calculate the hashCode of the contents of this AnyVersionedMap to reduce hash collisions as much as possible, even iterating over the full contents in necessary.

APPROXIMATE_FAST

public static final ContentHashCode APPROXIMATE_FAST

Compute an approximate hashCode of the contents of this AnyVersionedMap that may have a large number of hash collisions, but can be calculated without iterating over the full contents.

In the extreme case, AnyVersionedMap.contentHashCode(ContentHashCode) may return the same hashCode irrespectively of the actual contents of the AnyVersionedMap.

Method Details

values

public static ContentHashCode[] values()

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

Returns:

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

valueOf

public static ContentHashCode valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
