Method Detail

values

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

Returns:

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

valueOf

public static VanillaBytesHash 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

agitate

public static long agitate(long l)

hash

public long hash(Bytes bytes,
                 long offset,
                 long limit)

Description copied from interface: BytesHasher

Provide a 64-bit hash for the bytes between offset and limit

Specified by:

hash in interface BytesHasher

Parameters:

bytes - to hash

offset - the start inclusive

limit - the end exclusive

Returns:

64-bit hash.

hash

public long hash(Bytes bytes)

Description copied from interface: BytesHasher

Provide a 64-bit hash for the bytes in Bytes between the bytes.position() and bytes.limit();

Specified by:

hash in interface BytesHasher

Parameters:

bytes - to hash

Returns:

64-bit hash
