Enum KeyValue.Type

java.lang.Object

java.lang.Enum<KeyValue.Type>

org.apache.hadoop.hbase.KeyValue.Type

All Implemented Interfaces:

Serializable, Comparable<KeyValue.Type>

Enclosing class:

KeyValue

public static enum KeyValue.Type
extends Enum<KeyValue.Type>

Key type. Has space for other key types to be added later. Cannot rely on enum ordinals . They change if item is removed or moved. Do our own codes.

Method Detail

values

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

Returns:

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

valueOf

public static KeyValue.Type 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

getCode

public byte getCode()

isValidType

static boolean isValidType(byte b)

True to indicate that the byte b is a valid type.

Parameters:

b - byte to check

Returns:

true or false

codeToType

public static KeyValue.Type codeToType(byte b)

Cannot rely on enum ordinals . They change if item is removed or moved. Do our own codes.

Parameters:

b - the kv serialized byte[] to process

Returns:

Type associated with passed code.
