Enum Constant Detail

NO_HEADER

public static final ZlibDecompressor.CompressionHeader NO_HEADER

No headers/trailers/checksums.

DEFAULT_HEADER

public static final ZlibDecompressor.CompressionHeader DEFAULT_HEADER

Default headers/trailers/checksums.

GZIP_FORMAT

public static final ZlibDecompressor.CompressionHeader GZIP_FORMAT

Simple gzip headers/trailers.

AUTODETECT_GZIP_ZLIB

Method Detail

values

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

Returns:

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

valueOf

public static ZlibDecompressor.CompressionHeader valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

windowBits

public int windowBits()
