All Implemented Interfaces:

Funnel<DbKey>, Serializable, Comparable<DbKeyCompressedFunnel>

public enum DbKeyCompressedFunnel
extends Enum<DbKeyCompressedFunnel>
implements Funnel<DbKey>

A funnel for a database key. Encodes the key in the following format: the number of significant bits in the key in unsigned LEB128 format; then the key bytes including significant bits (e.g., if there are 12 significant bits, ceil(12/8) = 2 bytes of the key will be written to the sink).

Method Detail

values

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

Returns:

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

valueOf

public static DbKeyCompressedFunnel 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

funnel

public void funnel(DbKey from,
                   PrimitiveSink into)

Description copied from interface: Funnel

Sends a stream of data from the from object into the sink into. There is no requirement that this data be complete enough to fully reconstitute the object later.
