Constructor Detail

BinaryEncoder

public BinaryEncoder(java.io.BufferedWriter writer)

Creates an encoder to make a BufferedWriter write byte/int arrays as Strings. This version uses 6 bits per character using 64 characters from '@' (ASCII 64). It inserts a platform specific newline/linefeed after every 80 characters.

Parameters:

writer -

BinaryEncoder

public BinaryEncoder(java.io.BufferedWriter writer,
                     int bitsPerCharacter,
                     int baseCharacter,
                     int lineLength)

Instantiates an encoder for byte/int arrays to String.

Parameters:

writer -

bitsPerCharacter - no of bits to be used per character

baseCharacter - lowest character, which encodes value '0'

lineLength - -1 (no LF/NL) or count of character after which a NL/LF is inserted

Method Detail

toString

public static java.lang.String toString(int[] data,
                                        int dataBitCount)

Convenience method to directly encode an int array into a String Uses 6 bits per character using 64 characters from '@' (ASCII 64).

Parameters:

data -

dataBitCount -

Returns:

toString

public static java.lang.String toString(byte[] data,
                                        int dataBitCount)

Convenience method to directly encode a byte array into a String Uses 6 bits per character using 64 characters from '@' (ASCII 64).

Parameters:

data -

dataBitCount -

Returns:

initialize

public void initialize(int dataBitCount,
                       int totalByteCount)
                throws java.io.IOException

Initializes encoder for writing one binary array

Parameters:

dataBitCount - count of bits to be written per data value

totalByteCount - count of data values to be encoded

Throws:

java.io.IOException

write

public void write(int data)
           throws java.io.IOException

Encodes and writes one data value

Parameters:

data -

Throws:

java.io.IOException

finalize

public void finalize()
              throws java.io.IOException

Writes remaining bits from buffer, if there are any and possibly adds final NL/LF.

Overrides:

finalize in class java.lang.Object

Throws:

java.io.IOException
