Constructor Detail

VerticalPart

public VerticalPart(double top,
                    double bottom,
                    S segment)

Creates a new VerticalPart object.

Parameters:

top - the top ordinate of the part

bottom - the bottom ordinate of the part

segment - the ID of the segment this part belongs to

VerticalPart

public VerticalPart(S segment)

Creates a new VerticalPart object as a projection of a Segment instance.

Parameters:

segment - the Segment to project

Method Detail

getTop

public double getTop()

Returns the top ordinate of the part.

Returns:

the top ordinate of the part.

getBottom

public double getBottom()

Returns the bottom ordinate of the part.

Returns:

the bottom ordinate of the part.

getSegment

public S getSegment()

Returns the ID of the segment this part belongs to.

Returns:

the ID of the segment this part belongs to.

intersects

public boolean intersects(S segment)

Returns whether this part intersects the projection of the given segment.

Parameters:

segment - - the segment to check for intersection

Returns:

whether this part intersects the projection of the given segment.

compareTo

public int compareTo(java.lang.Object op)

Compares this part to another VerticalPart. Compares with a priority to the top endpoint, than the bottom one.

Specified by:

compareTo in interface java.lang.Comparable

Parameters:

op - the VerticalPart to compare to

Returns:

-1 if this part is smaller (higher than p), 0 if they are equal and 1 if this part is lower.
