Constructor Detail

LumberjackDecoder

public LumberjackDecoder(Charset charset)

Deprecated.

Parameters:

charset - the charset to decode bytes from the Lumberjack frame

LumberjackDecoder

public LumberjackDecoder(Charset charset,
                         ByteArrayOutputStream buffer)

Deprecated.

Parameters:

charset - the charset to decode bytes from the Lumberjack frame

buffer - a buffer to use while processing the bytes
