55/**
56 * This dialog helps to resolve conflicts occurring when ways are combined or
57 * nodes are merged.
58 *
59 * Usage: {@link #launchIfNecessary} followed by {@link #buildResolutionCommands}.
60 *
61 * Prior to {@link #launchIfNecessary}, the following usage sequence was needed:
62 *
63 * There is a singleton instance of this dialog which can be retrieved using
64 * {@link #getInstance()}.
65 *
66 * The dialog uses two models: one for resolving tag conflicts, the other
67 * for resolving conflicts in relation memberships. For both models there are accessors,
68 * i.e {@link #getTagConflictResolverModel()} and {@link #getRelationMemberConflictResolverModel()}.
69 *
70 * Models have to be <strong>populated</strong> before the dialog is launched. Example:
71 * <pre>
72 * CombinePrimitiveResolverDialog dialog = CombinePrimitiveResolverDialog.getInstance();
73 * dialog.getTagConflictResolverModel().populate(aTagCollection);
74 * dialog.getRelationMemberConflictResolverModel().populate(aRelationLinkCollection);
75 * dialog.prepareDefaultDecisions();
76 * </pre>
77 *
78 * You should also set the target primitive which other primitives (ways or nodes) are
79 * merged to, see {@link #setTargetPrimitive(OsmPrimitive)}.
80 *
81 * After the dialog is closed use {@link #isApplied()} to check whether the dialog has been
82 * applied. If it was applied you may build a collection of {@link Command} objects
83 * which reflect the conflict resolution decisions the user made in the dialog:
84 * see {@link #buildResolutionCommands()}
