Enum HiveMetaStoreClientWithLocalCache.KeyType

java.lang.Object

java.lang.Enum<HiveMetaStoreClientWithLocalCache.KeyType>

org.apache.hadoop.hive.ql.metadata.HiveMetaStoreClientWithLocalCache.KeyType

All Implemented Interfaces:

Serializable, Comparable<HiveMetaStoreClientWithLocalCache.KeyType>

Enclosing class:

HiveMetaStoreClientWithLocalCache

public static enum HiveMetaStoreClientWithLocalCache.KeyType
extends Enum<HiveMetaStoreClientWithLocalCache.KeyType>

KeyType is used to differentiate the request types. More types can be added in future. We added the unique classes that are part of the key for each request as well as the class of the value stored in the cache: At initialization time, they will be registered within the size estimator, which will be used to estimate the size of the objects within the cache.

Method Detail

values

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

Returns:

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

valueOf

public static HiveMetaStoreClientWithLocalCache.KeyType 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
