java.lang.Object java.io.InputStream org.rosuda.JRclient.RFileInputStream
RFileInputStream is an InputStream
to transfer files
from Rserve server to the client. It is used very much like
a FileInputStream
. Currently mark and seek is not supported.
The current implementation is also "one-shot" only, that means the file
can be read only once.
Method Summary | |
void |
close()
close stream - is not related to the actual Rconnection, calling close does not close the Rconnection |
int |
read()
reads one byte from the file. |
int |
read(byte[] b,
int off,
int len)
Reads specified number of bytes (or less) from the remote file. |

Method Detail |
public int read() throws IOException
RFileInputStream
provides no buffering. This means that each
call to this function leads to a complete packet exchange between
the server and the client. Use read(byte[],int,int)
instead
whenever possible. In fact this function calls #read(b,0,1)
.
IOException
public int read(byte[] b, int off, int len) throws IOException
b
- buffer to store the read bytesoff
- offset where to strat filling the bufferlen
- maximal number of bytes to read
IOException
public void close() throws IOException
