Enum Constant Detail

BZIP2

public static final CompressionType BZIP2

Constant used to identify the BZIP2 compression algorithm.

GZIP

public static final CompressionType GZIP

Constant used to identify the GZIP compression algorithm.

XZ

public static final CompressionType XZ

Constant used to identify the XZ compression algorithm.

PACK200

public static final CompressionType PACK200

Constant used to identify the PACK200 compression algorithm.

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

getName

public String getName()

Returns the name by which the compression algorithm is identified.

Returns:

the compression algorithm name

getDefaultFileExtension

public String getDefaultFileExtension()

Returns the default file extension for this compression type. E.g. ".gz" for gzip.

Returns:

the default file extension preceded by a dot

isValidCompressionType

public static boolean isValidCompressionType(String compression)

Checks if the given compression type name is valid and known format.

Parameters:

compression - the compression algorithm name

Returns:

true true if the given compression type is known to the factory, false otherwise

fromString

public static CompressionType fromString(String compression)

Attempts to return the CompressionType instance from a possible given string representation. Ignores case.

Parameters:

compression - string representation of the compression type. E.g. "GZIP".

Returns:

the compression type enum

Throws:

IllegalArgumentException - if the given compression type is unknown.
