Enum ZlibCompressor.CompressionStrategy

    java.lang.Object
      java.lang.Enum<ZlibCompressor.CompressionStrategy>
          org.apache.hadoop.io.compress.zlib.ZlibCompressor.CompressionStrategy

All Implemented Interfaces:
  Serializable, Comparable<ZlibCompressor.CompressionStrategy>

Enclosing class:
  ZlibCompressor

    public static enum ZlibCompressor.CompressionStrategy

extends Enum<ZlibCompressor.CompressionStrategy>

The compression level for zlib library.

Enum Constant Summary
`DEFAULT_STRATEGY` Default compression strategy.
`FILTERED` Compression strategy best used for data consisting mostly of small values with a somewhat random distribution.
`FIXED` Compression strategy to prevent the use of dynamic Huffman codes, allowing for a simpler decoder for special applications.
`HUFFMAN_ONLY` Compression strategy for Huffman coding only.
`RLE` Compression strategy to limit match distances to one (run-length encoding).

Method Summary
`static ZlibCompressor.CompressionStrategy` `valueOf(String name)` Returns the enum constant of this type with the specified name.
`static ZlibCompressor.CompressionStrategy[]` `values()` Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

### FILTERED

    public static final ZlibCompressor.CompressionStrategy FILTERED

  Compression strategy best used for data consisting mostly of small values with a somewhat random distribution. Forces more Huffman coding and less string matching.

### HUFFMAN_ONLY

    public static final ZlibCompressor.CompressionStrategy HUFFMAN_ONLY

  Compression strategy for Huffman coding only.

### RLE

    public static final ZlibCompressor.CompressionStrategy RLE

  Compression strategy to limit match distances to one (run-length encoding).

### FIXED

    public static final ZlibCompressor.CompressionStrategy FIXED

  Compression strategy to prevent the use of dynamic Huffman codes, allowing for a simpler decoder for special applications.

### DEFAULT_STRATEGY

    public static final ZlibCompressor.CompressionStrategy DEFAULT_STRATEGY

  Default compression strategy.

Method Detail

### values

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

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

### valueOf

    public static ZlibCompressor.CompressionStrategy 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
