Constructor Details

Http4RandomAccessContent

Http4RandomAccessContent(Http4FileObject<FS> fileObject,
 RandomAccessMode mode)

Method Details

close

public void close()
           throws IOException

Description copied from interface: RandomAccessContent

Closes this random access file stream and releases any system resources associated with the stream.

A closed random access file cannot perform input or output operations and cannot be reopened.

If this file has an associated channel then the channel is closed as well.

Throws:

IOException - if an I/O error occurs.

getDataInputStream

protected DataInputStream getDataInputStream()
                                      throws IOException

Specified by:

getDataInputStream in class AbstractRandomAccessStreamContent

Throws:

IOException

getFilePointer

public long getFilePointer()
                    throws IOException

Description copied from interface: RandomAccessContent

Returns the current offset in this file.

Returns:

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

Throws:

IOException - if an I/O error occurs.

length

public long length()
            throws IOException

Description copied from interface: RandomAccessContent

Returns the length of this file.

Returns:

the length of this file, measured in bytes.

Throws:

IOException - if an I/O error occurs.

seek

public void seek(long pos)
          throws IOException

Description copied from interface: RandomAccessContent

Sets the file-pointer offset, measured from the beginning of this 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.

Notice: If you use RandomAccessContent.getInputStream() you have to re-get the InputStream after calling RandomAccessContent.seek(long)

Parameters:

pos - the offset position, measured in bytes from the beginning of the file, at which to set the file pointer.

Throws:

IOException - if pos is less than 0 or if an I/O error occurs.
