read
public int read() throws java.io.IOExceptionReads enough of the input stream to convert to/from Base64 and returns the next byte.- Overrides:
read
in classjava.io.FilterInputStream
- Returns:
- next byte
- Throws:
java.io.IOException
- Since:
- 1.3
-
read
public int read(byte[] dest, int off, int len) throws java.io.IOExceptionCallsread()
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.- Overrides:
read
in classjava.io.FilterInputStream
- Parameters:
dest
- array to hold valuesoff
- offset for arraylen
- max number of bytes to read into array- Returns:
- bytes read into array or -1 if end of stream is encountered.
- Throws:
java.io.IOException
