Constructor Detail

Segment

public Segment(double pos,
               double start,
               double end)

Creates a new Segment object.

Parameters:

pos - the position of the new Segment

start - the start of the new Segment

end - the end of the new Segment

Method Detail

getPos

public double getPos()

Returns the segments position.

Returns:

the segments position.

setPos

public void setPos(double pos)

Changes the position of the segment without moving the corresponding element.

Parameters:

pos - the new abscissa

getStart

public double getStart()

Returns the start position of the segment.

Returns:

the start position of the segment.

getEnd

public double getEnd()

Returns the end position of the segment.

Returns:

the end position of the segment.

setStart

public void setStart(double start)

Sets the start position of the segment.

Parameters:

start - the new start position of the segment.

setEnd

public void setEnd(double end)

Sets the end position of the segment.

Parameters:

end - the new end position of the segment.

compareTo

public int compareTo(Segment s)

Compares the two specified segments by their pos value.

Specified by:

compareTo in interface java.lang.Comparable<Segment>

Parameters:

s - the segment to compare to

Returns:

the value 0 if both pos are numerically equal; a value less than 0 if the value of the first pos is numerically less than that of the second; and a value greater than 0 if d1 the value of the first pos is numerically greater than that of the second.
