Class Base64.InputStream
java.io.FilterInputStream
writer2latex.util.Base64.InputStream
- Base64
public static class Base64.InputStream
extends java.io.FilterInputStream
A
Base64.InputStream
will read data from another
java.io.InputStream, given in the constructor,
and encode/decode to/from Base64 notation on the fly.
int | read() - Reads enough of the input stream to convert
to/from Base64 and returns the next byte.
|
int | read(byte[] dest, int off, int len) - Calls
read() repeatedly until the end of stream
is reached or len bytes are read.

InputStream
public InputStream(java.io.InputStream in)
in
- the java.io.InputStream from which to read data.
InputStream
public InputStream(java.io.InputStream in,
int options)
Constructs a
Base64.InputStream
in
either ENCODE or DECODE mode.
Valid options:
ENCODE or DECODE: Encode or Decode as data is read.
DONT_BREAK_LINES: don't break lines at 76 characters
(only meaningful when encoding)
Note: Technically, this makes your encoding non-compliant.
Example:
new Base64.InputStream( in, Base64.DECODE )
in
- the java.io.InputStream from which to read data.options
- Specified options
read
public int read()
throws java.io.IOException
Reads enough of the input stream to convert
to/from Base64 and returns the next byte.
read
public int read(byte[] dest,
int off,
int len)
throws java.io.IOException
Calls
read()
repeatedly until the end of stream
is reached or
len bytes are read.
Returns number of bytes read into array or -1 if
end of stream is encountered.
dest
- array to hold valuesoff
- offset for arraylen
- max number of bytes to read into array
- bytes read into array or -1 if end of stream is encountered.
