Enum SyncReplicationState

java.lang.Object

java.lang.Enum<SyncReplicationState>

org.apache.hadoop.hbase.replication.SyncReplicationState

All Implemented Interfaces:

Serializable, Comparable<SyncReplicationState>

@InterfaceAudience.Public
public enum SyncReplicationState
extends Enum<SyncReplicationState>

Used by synchronous replication. Indicate the state of the current cluster in a synchronous replication peer. The state may be one of ACTIVE, DOWNGRADE_ACTIVE or STANDBY.

For asynchronous replication, the state is NONE.

Method Detail

values

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

Returns:

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

valueOf

public static SyncReplicationState 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

valueOf

public static SyncReplicationState valueOf(int value)

value

public int value()

toByteArray

public static byte[] toByteArray(SyncReplicationState state)

parseFrom

public static SyncReplicationState parseFrom(byte[] bytes)
                                      throws org.apache.hbase.thirdparty.com.google.protobuf.InvalidProtocolBufferException

Throws:

org.apache.hbase.thirdparty.com.google.protobuf.InvalidProtocolBufferException

toByteArray

public static byte[] toByteArray(SyncReplicationState state,
                                 SyncReplicationState newState)

parseStateAndNewStateFrom

public static Pair<SyncReplicationState,SyncReplicationState> parseStateAndNewStateFrom(byte[] bytes)
                                                                                 throws IOException

Throws:

IOException
