Method Detail

values

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

Returns:

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

valueOf

public static Compression 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

byExtension

public static Compression byExtension(java.lang.String name)

Determines the compression type depending on the suffix of name.

Parameters:

name - File name including extension

Returns:

the compression type

forContentType

public static Compression forContentType(java.lang.String contentType)

Determines the compression type based on the content type (MIME type).

Parameters:

contentType - the content type

Returns:

the compression type

getUncompressedInputStream

public java.io.InputStream getUncompressedInputStream(java.io.InputStream in)
                                               throws java.io.IOException

Returns an un-compressing InputStream for in.

Parameters:

in - raw input stream

Returns:

un-compressing input stream

Throws:

java.io.IOException - if any I/O error occurs

getUncompressedFileInputStream

public static java.io.InputStream getUncompressedFileInputStream(java.io.File file)
                                                          throws java.io.IOException

Returns an un-compressing InputStream for the File file.

Parameters:

file - file

Returns:

un-compressing input stream

Throws:

java.io.IOException - if any I/O error occurs

getCompressedOutputStream

public java.io.OutputStream getCompressedOutputStream(java.io.OutputStream out)
                                               throws java.io.IOException

Returns a compressing OutputStream for out.

Parameters:

out - raw output stream

Returns:

compressing output stream

Throws:

java.io.IOException - if any I/O error occurs

getCompressedFileOutputStream

public static java.io.OutputStream getCompressedFileOutputStream(java.io.File file)
                                                          throws java.io.IOException

Returns a compressing OutputStream for the File file.

Parameters:

file - file

Returns:

compressing output stream

Throws:

java.io.IOException - if any I/O error occurs
