Class Base64InputStream
FilterInputStreamgnu.mail.util.Base64InputStream
public class Base64InputStream
extends FilterInputStream
A Base64 content transfer encoding filter stream.
From RFC 2045, section 6.8:
The Base64 Content-Transfer-Encoding is designed to represent
arbitrary sequences of octets in a form that need not be humanly
readable. The encoding and decoding algorithms are simple, but the
encoded data are consistently only about 33 percent larger than the
unencoded data.
Base64InputStream(InputStream in)- Constructs an input stream that decodes an underlying Base64-encoded
stream.
|
int | available()- Returns the number of bytes that can be read(or skipped over) from this
input stream without blocking by the next caller of a method for this
input stream.
|
int | read()- Reads the next byte of data from the input stream.
|
int | read(byte[] b, int off, int len)- Reads up to len bytes of data from the input stream into an array of
bytes.
