Method Summary

long	getFilePointer() Returns the current offset in the data, in bytes.
long	length() Gets the number of bytes of data.
void	seek(long pos) Sets the offset in the data, in bytes.

Method Detail

getFilePointer

long getFilePointer()
                    throws java.io.IOException

Returns the current offset in the data, in bytes.

Returns:

The offset in bytes relative to the beginning of the data.

Throws:

java.io.IOException - if an I/O error is encountered.

seek

void seek(long pos)
          throws java.io.IOException

Sets the offset in the data, in bytes. The offset may be set beyond the end of the data, and this does not change the data length. Only writing after setting the pointer beyond the end of the data will change the data size.

Parameters:

pos - The desired offset, in bytes.

Throws:

java.io.IOException - if pos is negative, or if an I/O error is encountered.

length

long length()
            throws java.io.IOException

Gets the number of bytes of data.

Returns:

The number of bytes of data.

Throws:

java.io.IOException - if an I/O error is encountered.
