Method Detail

encode

public void encode(float value,
                   ByteArrayOutputStream out)

Overrides:

encode in class Encoder

flush

public void flush(ByteArrayOutputStream out)

Description copied from class: Encoder

Write all values buffered in memory cache to OutputStream.

Specified by:

flush in class Encoder

Parameters:

out - - ByteArrayOutputStream

getOneItemMaxSize

public int getOneItemMaxSize()

Description copied from class: Encoder

When encoder accepts a new incoming data point, the maximal possible size in byte it takes to store in memory.

Overrides:

getOneItemMaxSize in class Encoder
