Method Details

close
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
- Specified by:
getDataInputStream
in classAbstractRandomAccessStreamContent
- Throws:
IOException
-
getFilePointer
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
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
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 callingRandomAccessContent.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
- ifpos
is less than0
or if an I/O error occurs.
