Class RelationMember

java.lang.Object
  org.openstreetmap.josm.data.osm.RelationMember

All Implemented Interfaces:

PrimitiveId

public class RelationMember
extends java.lang.Object
implements PrimitiveId

A linkage class that can be used by an relation to keep a list of members. Since membership may be qualified by a "role", a simple list is not sufficient.

Field Summary

private OsmPrimitive	member
private java.lang.String	role

Constructor Summary

RelationMember(RelationMember other)
Copy constructor.

RelationMember(java.lang.String role, OsmPrimitive member)

Node	getNode()
Relation	getRelation()
java.lang.String	getRole()
OsmPrimitiveType	getType() PrimitiveId implementation.
long	getUniqueId() PrimitiveId implementation.
Way	getWay()
int	hashCode()
boolean	hasRole()
boolean	isNew() Replies true if this id represents a new primitive.

Constructor Detail

RelationMember

public RelationMember(java.lang.String role,
                      OsmPrimitive member)
               throws java.lang.IllegalArgumentException

Parameters:

role - Can be null, in this case it's save as ""

member - Cannot be null

Throws:

java.lang.IllegalArgumentException

RelationMember

public RelationMember(RelationMember other)

Copy constructor. This constructor is left only for backwards compatibility. Copying RelationMember doesn't make sense because it's immutable
