Method Detail

values

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

Returns:

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

valueOf

public static CompressionType 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

deserialize

public static CompressionType deserialize(byte compressor)

deserialize byte number.

Parameters:

compressor - byte number

Returns:

CompressionType

getSerializedSize

public static int getSerializedSize()

serialize

public byte serialize()

Returns:

byte number

getExtension

public String getExtension()

get extension.

Returns:

extension (string type), for example: .snappy, .gz, .lzo
