public interface InputDataFileInterface

A general interface for input data files of finite length that can be rewound, positioned, marked, etc. A data file has units of data, e.g. events for AE data, frames for frame-based data.

Method Summary

float	getFractionalPosition()
void	mark() mark the current position.
int	position() return position in events
void	position(int n) set position in units of the file, e.g.
void	rewind() rewind to the start, or to the marked position, if it has been set
void	setFractionalPosition(float frac) Sets fractional position in units of the file
long	size()
void	unmark() clear any marked position

Method Detail

getFractionalPosition

float getFractionalPosition()

Returns:

fractional position in total events

mark

void mark()
          throws java.io.IOException

mark the current position.

Throws:

java.io.IOException - if there is some error in reading the data

position

int position()

return position in events

position

void position(int n)

set position in units of the file, e.g. events or frames

Parameters:

n - the number to position to

rewind

void rewind()
            throws java.io.IOException

rewind to the start, or to the marked position, if it has been set

Throws:

java.io.IOException

setFractionalPosition

void setFractionalPosition(float frac)

Sets fractional position in units of the file

Parameters:

frac - 0-1 float range, 0 at start, 1 at end

size

long size()

Returns:

size in units of the file

unmark

void unmark()

clear any marked position
