Constructor Detail

Intersection

public Intersection(java.awt.geom.Point2D interPoint,
                    double tolerance)

Allocates a new intersection

Parameters:

interPoint - the spatial point where the intersection happened

tolerance - tolerance used to detect all the elements involved in the interaction

Method Detail

getId

public long getId()

Gets the intersection ID

Returns:

the intersection ID

getMembersCount

public int getMembersCount()

Gets the number of elements participating in the intersection

Returns:

the number of elements in the intersection

addMember

public void addMember(IntersectionMember<V> member)

Adds a member to the intersection

Parameters:

member - an intersection member

removeMember

public void removeMember(IntersectionMember<V> member)

Removes an intersection member

Parameters:

member - an intersection member

containsMember

public boolean containsMember(IntersectionMember<V> member)

Tells whether an intersection member belongs to the current intersection

Parameters:

member - an intersection member

Returns:

true if it is a member of the intersection

getMembers

public java.util.Collection<IntersectionMember<V>> getMembers()

Gets all the members of the intersection

Returns:

a collection of intersection members

markAsOwner

public void markAsOwner(IntersectionMember<V> member)

Sets the given member as the owner of the intersection. An intersection may not have an owner. An owner can be the element that creates the interaction, for example, an element that was added or that was moved.

Parameters:

member - a member of the intersection

isOwner

public boolean isOwner(IntersectionMember<V> member)

Tells whether the given member is owner of the intersection.

Parameters:

member - a member of the intersection

Returns:

true if the element is the owner

getOwner

public IntersectionMember<V> getOwner()

Gets the member marked as intersection owner (if any)

Returns:

an intersection member or null if the intersection has not owner member

getIntersectionPoint

public java.awt.geom.Point2D getIntersectionPoint()

Gets the spatial point where the intersection occurred

Returns:

a java point

setIntersectionPoint

public void setIntersectionPoint(java.awt.geom.Point2D interPoint)

Sets the spatial point where the intersection occurred

Parameters:

interPoint - a java point

pickFirstMember

public IntersectionMember<V> pickFirstMember(int geomType)

Gets the first member found with the given geometry type

Parameters:

geomType - a geometry type

Returns:

the first member found or null if no members were found

getMembers

public java.util.Collection<IntersectionMember<V>> getMembers(int geomType)

Gets all the members with the given geometry type

Parameters:

geomType - a geometry type

Returns:

a collection of intersection members

getMember

public IntersectionMember<V> getMember(long memId)

Gets a member identified by the given ID

Parameters:

memId - an intersection member ID

Returns:

an intersection member of null if the member was not found

getTolerance

public double getTolerance()

Gets the tolerance used to detect the intersection

Returns:

a tolerance value

setTolerance

public void setTolerance(double tolerance)

Sets the tolerance used to detect the intersection

Parameters:

tolerance - a tolerance value

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Overrides:

clone in class java.lang.Object

Throws:

java.lang.CloneNotSupportedException
