Indicator interface that identifies geometries that can have persistent point ID values attached to coordinates.

#### Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

#### Description

Indentifies objects that can have and use PointIDs. An object will only use its PointID attributes if it is set to be Aware of them.

#### Members

Description |

---|---|---|

DropPointIDs | Unsets all PointID values without changing awareness. Only works if geometry is aware of PointIDs. | |

PointIDAware | Indicates whether or not the geometry is aware of and capable of handling PointIDs. | |

PointIDSimple | Indicates if all PointID values for this geometry are well-defined. Only works if geometry is aware of PointIDs. |

CoClasses and Classes | Description |
---|---|

MultiPatch | A collection of surface patches. |

Multipoint | An ordered collection of points; optionally has measure, height and ID attributes. |

Point | A two dimensional point, optionally with measure, height, and ID attributes. |

Polygon | A collection of rings ordered by their containment relationship; optionally has measure, height and ID attributes. |
