Methods

Modifier and Type	Method and Description
byte	getByteCode() The byte that indicates this KeyType.
int	getEncodedLength() The #of bytes in which values of that KeyType are encoded -or- zero (0) iff values are encoded in a variable number of bytes with a nul terminator for the byte sequence.
static KeyType	getKeyType(byte b) Return the KeyType given its byte code.
boolean	isFixedLength() True iff the key type is encoded in a fixed #of bytes.
static KeyType	valueOf(String name) Returns the enum constant of this type with the specified name.
static KeyType[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

public static 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 (KeyType c : 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 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

isFixedLength

public boolean isFixedLength()

True iff the key type is encoded in a fixed #of bytes.

getEncodedLength

public int getEncodedLength()

The #of bytes in which values of that KeyType are encoded -or- zero (0) iff values are encoded in a variable number of bytes with a nul terminator for the byte sequence.

getByteCode

public byte getByteCode()

The byte that indicates this KeyType.

Returns:

getKeyType

public static KeyType getKeyType(byte b)

Return the KeyType given its byte code.

Parameters:

b - The byte code.

Returns:

The KeyType.
