Enum IsolationLevel

java.lang.Object

java.lang.Enum<IsolationLevel>

org.apache.hadoop.hbase.client.IsolationLevel

All Implemented Interfaces:

Serializable, Comparable<IsolationLevel>

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

Specify Isolation levels in Scan operations.

There are two isolation levels. A READ_COMMITTED isolation level indicates that only data that is committed be returned in a scan. An isolation level of READ_UNCOMMITTED indicates that a scan should return data that is being modified by transactions that might not have been committed yet.

Method Detail

values

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

Returns:

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

valueOf

public static IsolationLevel 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
