Encoder
protected Encoder(char[] pBuffer, int pWrapSize, String pSep)
Creates a new instance.- Parameters:
pBuffer
- The encoders buffer. The encoder will write to the buffer as long as possible. If the buffer is full or the end of data is signaled, then the methodwriteBuffer(char[], int, int)
will be invoked.pWrapSize
- A nonzero value indicates, that a line wrap should be performed after the given number of characters. The value must be a multiple of 4. Zero indicates, that no line wrap should be performed.pSep
- The eol sequence being used to terminate a line in case of line wraps. May be null, in which case the default valueBase64.LINE_SEPARATOR
is being used.

writeBuffer
protected abstract void writeBuffer(char[] pChars, int pOffset, int pLen) throws IOException
Called for writing the buffer contents to the target.- Parameters:
pChars
- The buffer being written.pOffset
- Offset of first character being written.pLen
- Number of characters being written.- Throws:
IOException
- Writing to the destination failed.
-
write
public void write(byte[] pBuffer, int pOffset, int pLen) throws IOException
Encodes the given byte array.- Parameters:
pBuffer
- Byte array being encoded.pOffset
- Offset of first byte being encoded.pLen
- Number of bytes being encoded.- Throws:
IOException
- Invoking thewriteBuffer(char[],int,int)
method for writing the encoded data failed.
-
flush
public void flush() throws IOException
Writes any currently buffered data to the destination.- Throws:
IOException
- Invoking thewriteBuffer(char[],int,int)
method for writing the encoded data failed.
