java.lang.Enum<MemStoreCompactionStrategy.Action>

org.apache.hadoop.hbase.regionserver.MemStoreCompactionStrategy.Action

All Implemented Interfaces:

Serializable, Comparable<MemStoreCompactionStrategy.Action>

Enclosing class:

MemStoreCompactionStrategy

public static enum MemStoreCompactionStrategy.Action
extends Enum<MemStoreCompactionStrategy.Action>

Types of actions to be done on the pipeline upon MemStoreCompaction invocation. Note that every value covers the previous ones, i.e. if MERGE is the action it implies that the youngest segment is going to be flatten anyway.

Method Detail

values

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

Returns:

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

valueOf

public static MemStoreCompactionStrategy.Action 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
