ContentInputBufferlen bytes of data from this buffer into
an array of bytes. The exact number of bytes read depends how many bytes
are stored in the buffer.
If off is negative, or len is negative, or
off+len is greater than the length of the array
b, this method can throw a runtime exception. The exact type
of runtime exception thrown by this method depends on implementation.
This method returns -1 if the end of content stream has been
reached.

at which the data is written.len - the maximum number of bytes to read.-1 if there is no more data because the end of
