Enum FileType

java.lang.Object

java.lang.Enum<FileType>

org.torproject.metrics.collector.webstats.FileType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<FileType>

public enum FileType
extends java.lang.Enum<FileType>

These enums provide compression functionality.

findType(java.lang.String) determines the compression type by the given extension. Compression can also be zero-compression, which is currently provided by the PLAIN and JSON enums.

Method Detail

values

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

Returns:

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

valueOf

public static FileType 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

findType

public static FileType findType(java.lang.String ext)

Returns valueOf or the default enum PLAIN, i.e., this method doesn't throw any exceptions and allways returns a valid enum.

inputStream

public java.io.InputStream inputStream(java.io.InputStream is)
                                throws java.lang.Exception

Return the appropriate input stream.

Throws:

java.lang.Exception

outputStream

public java.io.OutputStream outputStream(java.io.OutputStream os)
                                  throws java.lang.Exception

Return the appropriate output stream.

Throws:

java.lang.Exception

compress

public byte[] compress(byte[] bytes)
                throws java.lang.Exception

Compresses the given bytes in memory and returns the compressed bytes.

Throws:

java.lang.Exception

compress

public java.io.OutputStream compress(java.io.OutputStream os)
                              throws java.lang.Exception

Compresses the given InputStream and returns an OutputStream.

Throws:

java.lang.Exception

decompress

public java.io.InputStream decompress(java.io.InputStream is)
                               throws java.lang.Exception

Decompresses the given InputStream and returns an OutputStream.

Throws:

java.lang.Exception

decompress

public byte[] decompress(byte[] bytes)
                  throws java.lang.Exception

Decompresses the given bytes in memory and returns the decompressed bytes.

Throws:

java.lang.Exception
