getFilePointer
public long getFilePointer()
throws java.io.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:
java.io.IOException
- if an I/O error occurs.
seek
public void seek(long pos)
throws java.io.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 reget 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:
java.io.IOException
- if pos
is less than
0
or if an I/O error occurs.
getDataInputStream
protected java.io.DataInputStream getDataInputStream()
throws java.io.IOException
- Specified by:
getDataInputStream
in class AbstractRandomAccessStreamContent
- Throws:
java.io.IOException
close
public void close()
throws java.io.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:
java.io.IOException
- if an I/O error occurs.
length
public long length()
throws java.io.IOException
- Description copied from interface:
RandomAccessContent
- Returns the length of this file.
- Returns:
- the length of this file, measured in bytes.
- Throws:
java.io.IOException
- if an I/O error occurs.
