Enum Constant Detail

NONE

public static final SequenceFile.CompressionType NONE
Do not compress records.


RECORD

public static final SequenceFile.CompressionType RECORD
Compress values only, each separately.


BLOCK

public static final SequenceFile.CompressionType BLOCK
Compress sequences of records together in blocks.

Method Detail

values

public static SequenceFile.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 (SequenceFile.CompressionType c : SequenceFile.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 SequenceFile.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
