Constructor Detail

SmbFileInputStream

public SmbFileInputStream(java.lang.String url)
                   throws SmbException,
                          java.net.MalformedURLException,
                          java.net.UnknownHostException
Creates an InputStream for reading bytes from a file on an SMB server addressed by the url parameter. See SmbFile for a detailed description and examples of the smb URL syntax.

Parameters:
url - An smb URL string representing the file to read from

SmbFileInputStream

public SmbFileInputStream(jcifs.smb.SmbFile file)
                   throws SmbException,
                          java.net.MalformedURLException,
                          java.net.UnknownHostException
Creates an InputStream for reading bytes from a file on an SMB server represented by the SmbFile parameter. See SmbFile for a detailed description and examples of the smb URL syntax.

Parameters:
file - An SmbFile specifying the file to read from
Method Detail

close

public void close()
           throws java.io.IOException
Closes this input stream and releases any system resources associated with the stream.

Overrides:
close in class java.io.InputStream
Throws:
java.io.IOException - if a network error occurs

read

public int read()
         throws java.io.IOException
Reads a byte of data from this input stream.

Specified by:
read in class java.io.InputStream
Throws:
java.io.IOException - if a network error occurs

read

public int read(byte[] b)
         throws java.io.IOException
Reads up to b.length bytes of data from this input stream into an array of bytes.

Overrides:
read in class java.io.InputStream
Throws:
java.io.IOException - if a network error occurs

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException
Reads up to len bytes of data from this input stream into an array of bytes.

Overrides:
read in class java.io.InputStream
Throws:
java.io.IOException - if a network error occurs

available

public int available()
              throws java.io.IOException
This stream class is unbuffered. Therefore this method will always return 0 for streams connected to regular files. However, a stream created from a Named Pipe this method will query the server using a "peek named pipe" operation and return the number of available bytes on the server.

Overrides:
available in class java.io.InputStream
java.io.IOException

skip

public long skip(long n)
          throws java.io.IOException
Skip n bytes of data on this stream. This operation will not result in any IO with the server. Unlink InputStream value less than the one provided will not be returned if it exceeds the end of the file (if this is a problem let us know).

Overrides:
skip in class java.io.InputStream
java.io.IOException
