Method Detail

init

public void init(Compression.Type type,
                 int level)

Parameters:

type - compression type

level - compression level

isCompressionExecuted

public boolean isCompressionExecuted()

Specified by:

isCompressionExecuted in interface CompressionInformation

Overrides:

isCompressionExecuted in class BaseCompression

Returns:

true if there is any compression executed by this "compressor" - special case for 'none'
