public int read(byte[] data,
int offset,
int length)
InputStreamlen bytes of data from the input stream into
an array of bytes. An attempt is made to read as many as
len bytes, but a smaller number may be read, possibly
zero. The number of bytes actually read is returned as an integer.
This method blocks until input data is available, end of file is detected, or an exception is thrown.
If b is null, a
NullPointerException is thrown.
If off is negative, or len is negative, or
off+len is greater than the length of the array
b, then an IndexOutOfBoundsException is
thrown.
If len is zero, then no bytes are read and
0 is returned; otherwise, there is an attempt to read at
least one byte. If no byte is available because the stream is at end of
file, the value -1 is returned; otherwise, at least one
byte is read and stored into b.
The first byte read is stored into element b[off], the
next one into b[off+1], and so on. The number of bytes read
is, at most, equal to len. Let k be the number of
bytes actually read; these bytes will be stored in elements
b[off] through b[off+k-1],
leaving elements b[off+k] through
b[off+len-1] unaffected.
In every case, elements b[0] through
b[off] and elements b[off+len] through
b[b.length-1] are unaffected.
If the first byte cannot be read for any reason other than end of
file, then an IOException is thrown. In particular, an
IOException is thrown if the input stream has been closed.
The read(b, off, len) method
for class InputStream simply calls the method
read() repeatedly. If the first such call results in an
IOException, that exception is returned from the call to
the read(b, off, len) method. If
any subsequent call to read() results in a
IOException, the exception is caught and treated as if it
were end of file; the bytes read up to that point are stored into
b and the number of bytes read before the exception
occurred is returned. Subclasses are encouraged to provide a more
efficient implementation of this method.

at which the data is written.length - the maximum number of bytes to read.

You would call this function in the case that the contents of the message is detached from the actual CMS encoding. For example, in a clear signed SMIME message, the text ( what is signed ) is in a different MIME part then the CMS encoding. You could use this function to give CMS an input stream that points to the MIME part containing the text of the message.
setData in class CMSInputStreamdata - The input stream containing the data.
IOException - Thrown if an IO error occurs.
CMSException - Thrown if a cms error occurs.
CryptoTokenException - Thrown if an error occurs with a crypto
token or the crypto token is invalid.
KeyStoreCancelException - Thrown if the user fails to enter a
password or the password is invalid.
CryptoUnsupportedOperationException - Thrown if a call is made to an
unsupported operation.
UnsupportedCryptoSystemException - Thrown if the specified crypto
system is invalid.
InvalidCryptoSystemException - Thrown if the specified crypto
system is invalid.
InvalidKeyException - Thrown if the specified key is invalid.
InvalidKeyEncodingException - Thrown if the key is improperly formatted.public boolean isContentComplete()
