Enum SplittableCompressionCodec.READ_MODE
java.lang.Object
java.lang.Enum<SplittableCompressionCodec.READ_MODE>
org.apache.hadoop.io.compress.SplittableCompressionCodec.READ_MODE
- All Implemented Interfaces:
- Serializable, Comparable<SplittableCompressionCodec.READ_MODE>
- Enclosing interface:
- SplittableCompressionCodec
public static enum SplittableCompressionCodec.READ_MODE
- extends Enum<SplittableCompressionCodec.READ_MODE>
During decompression, data can be read off from the decompressor in two
modes, namely continuous and blocked. Few codecs (e.g. BZip2) are capable
of compressing data in blocks and then decompressing the blocks. In
Blocked reading mode codecs inform 'end of block' events to its caller.
While in continuous mode, the caller of codecs is unaware about the blocks
and uncompressed data is spilled out like a continuous stream.
CONTINUOUS
public static final SplittableCompressionCodec.READ_MODE CONTINUOUS
BYBLOCK
public static final SplittableCompressionCodec.READ_MODE BYBLOCK
values
public static SplittableCompressionCodec.READ_MODE[] 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 (SplittableCompressionCodec.READ_MODE c : SplittableCompressionCodec.READ_MODE.values())
System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in
the order they are declared
valueOf
public static SplittableCompressionCodec.READ_MODE 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
