public static class SMBFile.SMBRandomAccessOutputStream
extends RandomAccessOutputStream

SMBRandomAccessOutputStream extends RandomAccessOutputStream to provide random write access to an SMBFile.

Constructor Summary

SMBFile.SMBRandomAccessOutputStream(jcifs.smb.SmbRandomAccessFile raf)

Method Summary

void	close() Closes this stream and releases any system resources associated with the stream.
long	getLength() Returns the length of the file, in bytes.
long	getOffset() Returns the offset (in bytes) from the beginning of the file at which the next read or write occurs.
void	seek(long offset) Sets the offset, measured from the beginning of the file, at which the next read or write occurs.
void	setLength(long newLength) Sets the length of the file.
void	write(byte[] b) Writes b.length bytes from the specified byte array to this file, starting at the current file offset.
void	write(byte[] b, int off, int len) Writes len bytes from the specified byte array starting at offset off to this file.
void	write(int i)

Constructor Detail

SMBFile.SMBRandomAccessOutputStream

public SMBFile.SMBRandomAccessOutputStream(jcifs.smb.SmbRandomAccessFile raf)

Method Detail

write

public void write(int i)
           throws java.io.IOException

Specified by:

write in class java.io.OutputStream

Throws:

java.io.IOException

write

public void write(byte[] b)
           throws java.io.IOException

Description copied from class: RandomAccessOutputStream

Writes b.length bytes from the specified byte array to this file, starting at the current file offset.

Specified by:

write in class RandomAccessOutputStream

Parameters:

b - the data to write

Throws:

java.io.IOException - if an I/O error occurs

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Description copied from class: RandomAccessOutputStream

Writes len bytes from the specified byte array starting at offset off to this file.

Specified by:

write in class RandomAccessOutputStream

Parameters:

b - the data to write

off - the start offset in the data array

len - the number of bytes to write

Throws:

java.io.IOException - if an I/O error occurs

close

public void close()
           throws java.io.IOException

Description copied from class: RandomAccessOutputStream

Closes this stream and releases any system resources associated with the stream. A closed stream cannot perform output operations and cannot be reopened.

Specified by:

close in interface RandomAccess

Specified by:

close in interface java.io.Closeable

Specified by:

close in class RandomAccessOutputStream

Throws:

java.io.IOException - if an I/O error occurs.

getOffset

public long getOffset()
               throws java.io.IOException

Description copied from interface: RandomAccess

Returns the offset (in bytes) from the beginning of the file at which the next read or write occurs.

Returns:

the offset (in bytes) from the beginning of the file at which the next read or write occurs

Throws:

java.io.IOException - if an I/O error occurs.

getLength

public long getLength()
               throws java.io.IOException

Description copied from interface: RandomAccess

Returns the length of the file, in bytes.

Returns:

the length of the file, in bytes

Throws:

java.io.IOException - if an I/O error occurs

seek

public void seek(long offset)
          throws java.io.IOException

Description copied from interface: RandomAccess

Sets the offset, measured from the beginning of the file, at which the next read or write occurs. The offset may be set beyond the end of the file. Setting the offset beyond the end of the file does not change the file length. The file length will change only by writing after the offset has been set beyond the end of the file.

Parameters:

offset - the new offset position, measured in bytes from the beginning of the file

Throws:

java.io.IOException - if an I/O error occurs

setLength

public void setLength(long newLength)
               throws java.io.IOException

Description copied from class: RandomAccessOutputStream

Sets the length of the file.

If the present length of the file as returned by the RandomAccess.getLength() method is greater than the newLength argument then the file will be truncated. In this case, if the file offset as returned by the RandomAccess.getOffset() method is greater than newLength then the offset will be equal to newLength after this method returns .

If the present length of the file as returned by the RandomAccess.getLength() method is smaller than the newLength argument then the file will be extended. In this case, the contents of the extended portion of the file are not defined.

Specified by:

setLength in class RandomAccessOutputStream

Parameters:

newLength - the new file's length

Throws:

java.io.IOException - If an I/O error occurred while trying to change the file's length
