SmbFileInputStream

public SmbFileInputStream(SmbFile file)
                   throws SmbException

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.

パラメータ:

file - An SmbFile specifying the file to read from

例外:

SmbException

メソッドの詳細

open

public void open()
          throws CIFSException

Ensures that the file descriptor is openend

例外:

CIFSException

seToIoe

protected static IOException seToIoe(SmbException se)

close

public void close()
           throws IOException

Closes this input stream and releases any system resources associated with the stream.

定義:

close インタフェース内 AutoCloseable

定義:

close インタフェース内 Closeable

オーバーライド:

close クラス内 InputStream

例外:

IOException - if a network error occurs

read

public int read()
         throws IOException

Reads a byte of data from this input stream.

定義:

read クラス内 InputStream

例外:

IOException - if a network error occurs

read

public int read(byte[] b)
         throws IOException

Reads up to b.length bytes of data from this input stream into an array of bytes.

オーバーライド:

read クラス内 InputStream

例外:

IOException - if a network error occurs

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Reads up to len bytes of data from this input stream into an array of bytes.

オーバーライド:

read クラス内 InputStream

例外:

IOException - if a network error occurs

readDirect

public int readDirect(byte[] b,
                      int off,
                      int len)
               throws IOException

Reads up to len bytes of data from this input stream into an array of bytes.

パラメータ:

b -

off -

len -

戻り値:

number of bytes read

例外:

IOException - if a network error occurs

available

public int available()
              throws 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.

オーバーライド:

available クラス内 InputStream

例外:

IOException

skip

public long skip(long n)
          throws 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).

オーバーライド:

skip クラス内 InputStream

例外:

IOException
