org.apache.ws.commons.util.Base64.Encoder
- Base64
public static abstract class Base64.Encoder
extends java.lang.Object
An encoder is an object, which is able to encode byte array
in blocks of three bytes. Any such block is converted into an
array of four bytes.
Encoder(char[] pBuffer, int pWrapSize, String pSep) - Creates a new instance.
|
void | flush() - Writes any currently buffered data to the destination.
|
void | write(byte[] pBuffer, int pOffset, int pLen) - Encodes the given byte array.
|
protected abstract void | writeBuffer(char[] pChars, int pOffset, int pLen) - Called for writing the buffer contents to the target.

Encoder
protected Encoder(char[] pBuffer,
int pWrapSize,
String pSep)
Creates a new instance.
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 method writeBuffer(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 value Base64.LINE_SEPARATOR
is being used.
flush
public void flush()
throws IOException
Writes any currently buffered data to the destination.
write
public void write(byte[] pBuffer,
int pOffset,
int pLen)
throws IOException
Encodes the given byte array.
pBuffer
- Byte array being encoded.pOffset
- Offset of first byte being encoded.pLen
- Number of bytes being encoded.
writeBuffer
protected abstract void writeBuffer(char[] pChars,
int pOffset,
int pLen)
throws IOException
Called for writing the buffer contents to the target.
pChars
- The buffer being written.pOffset
- Offset of first character being written.pLen
- Number of characters being written.
