Constructor Detail

AbstractHighwayMatrix

protected AbstractHighwayMatrix(List<Highway> highways)

Constructor. Creates the instance using list of the highways.

Parameters:

highways - - highways list

See Also:

IHighwayMatrix, Highway

Method Detail

addHighway

public int addHighway(Highway highway)

Creates new HighwayPtr using specified highway and adds it to the end of highway pointers list.

Specified by:

addHighway in interface IHighwayMatrix

Parameters:

highway - - the highway to be added to this matrix

Returns:

the index of the highway to be added

removeHighway

public Highway removeHighway(int index)

Removes the highway pointer at the specified position in the highway pointers list

Specified by:

removeHighway in interface IHighwayMatrix

Parameters:

index - - the index of the highway to be removed

Returns:

the highway that was removed from the matrix

getPoints

protected org.eclipse.draw2d.geometry.PointList getPoints(int[] path,
                                                          org.eclipse.draw2d.geometry.Point start,
                                                          org.eclipse.draw2d.geometry.Point end)

Creates the points list using specified path.

Parameters:

path - - array of the highways indexes

start - - start point (first element on the returned points list)

end - - end point (last element on the returned points list)

Returns:

the points list

getHighways

public Iterable<Highway> getHighways()

Gets the highways iterator

Specified by:

getHighways in interface IHighwayMatrix

Returns:

the highways iterator

getSize

protected int getSize()

Gets the size of the highways list

Returns:

the size of the highways list

getHighway

public Highway getHighway(int index)

Returns the highway at the specified position in list.

Specified by:

getHighway in interface IHighwayMatrix

Parameters:

index - - index of the highway to return

Throws:

IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= getSize())

getIdentifier

public int getIdentifier(Highway highway)

Returns the index of the specified highway, or -1 if highways list does not contain the element.

Specified by:

getIdentifier in interface IHighwayMatrix

Parameters:

highway - - element to search for

Returns:

the index of the specified highway, or -1 if highways list does not contain the element.

Throws:

NullPointerException - if the specified element is null

getHighwayPtr
