IColumnSerializer

public static enum IColumnSerializer.Flag
extends java.lang.Enum<IColumnSerializer.Flag>

Flag affecting deserialization behavior. - LOCAL: for deserialization of local data (Expired columns are converted to tombstones (to gain disk space)). - FROM_REMOTE: for deserialization of data received from remote hosts (Expired columns are converted to tombstone and counters have their delta cleared) - PRESERVE_SIZE: used when no transformation must be performed, i.e, when we must ensure that deserializing and reserializing the result yield the exact same bytes. Streaming uses this.

Method Detail

values

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

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

valueOf

public static IColumnSerializer.Flag valueOf(java.lang.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:
java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
java.lang.NullPointerException - if the argument is null
