Interface MutablePath<V extends Vertex,E extends Edge<V>>

All Superinterfaces:

Edge<V>, Path<V,E>

All Known Implementing Classes:

DefaultMutablePath

public interface MutablePath<V extends Vertex,E extends Edge<V>>
extends Path<V,E>

Abstraction of a mutable path that allows gradual construction.

Method Summary

Modifier and Type	Method and Description
void	appendEdge(E edge) Appends a new edge at the end of the this path.
void	insertEdge(E edge) Inserts a new edge at the beginning of this path.
void	removeEdge(E edge) Removes the specified edge.
void	setCost(Weight cost) Sets the total path cost as a weight object.
Path<V,E>	toImmutable() Returns an immutable copy of this path.

Method Detail

insertEdge

void insertEdge(E edge)

Inserts a new edge at the beginning of this path. The edge must be adjacent to the prior start of the path.

Parameters:

edge - edge to be inserted

appendEdge

void appendEdge(E edge)

Appends a new edge at the end of the this path. The edge must be adjacent to the prior end of the path.

Parameters:

edge - edge to be inserted

removeEdge

void removeEdge(E edge)

Removes the specified edge. This edge must be either at the start or at the end of the path, or it must be a cyclic edge in order not to violate the contiguous path property.

Parameters:

edge - edge to be removed

setCost

void setCost(Weight cost)

Sets the total path cost as a weight object.

Parameters:

cost - new path cost

toImmutable

Path<V,E> toImmutable()

Returns an immutable copy of this path.

Returns:

immutable copy
