| IlvObjectSDOLayer::IlvObjectSDOLayer | ( | const IlvMapAdapter * | mapAdapter, |
| IldDbms * | dbms, | ||
| const char * | tableName, | ||
| const char * | geometryColumnName, | ||
| IlDouble | tileWidth, | ||
| IlDouble | tileHeight, | ||
| const char * | xCoordinateColumnName = 0, |
||
| const char * | yCoordinateColumnName = 0, |

| const char * | keyColumnName = 0, |
||

||
| ) |
Initializes a new instance of IlvObjectSDOLayer.
Initializes an instance of IlvObjectSDOLayer to load data from the layer, specified by tableName, the name of the table containing the layer and geometryColumnName, the name of the column containing the geometry. This constructor will use an IlvDefaultObjectSDOTileLoader which has some optimizations.
| mapAdapter | The map adapter used by the layer. |
| dbms | The connection to an Oracle database. |
| tableName | The name of the layer table to be loaded. |
| geometryColumnName | The name of the geometry column of the layer. This parameter is useful if the layer has more than one geometry column. If your layer has only one geometry column, just set this parameter to 0. |
| tileWidth | The width of one load-on-demand tile. The width must be given in manager coordinate system (it will be adapted by the map adapter passed as argument). |
| tileHeight | The height of one load-on-demand tile. The height must be given in manager coordinate system (it will be adapted by the map adapter passed as argument). |
| xCoordinateColumnName | The name of the X dimension. If set to 0, the index of the X dimension in the metadata table (in the SDO_DIM_ARRAY) will be considered as 0. |
| yCoordinateColumnName | The name of the Y dimension. If set to 0, the index of the Y dimension in the metadata table (in the SDO_DIM_ARRAY) will be considered as 1. |
| keyColumnName | The name of the column containing an ID considered as a Key for each geometry. If this parameter is set, then the key value extracted from the keyColumnName column is associated to the IlvMapFeature as its IlvMapFeatureId. The interest of this is that a map feature containing a geometry that belongs to multiple tiles will be loaded just once. |
| password | The password the user gives in order to get connected to the Database. This parameter is also necessary to the IldNewDbms() function which creates an instance of IldDbms. You can set this parameter for the user's password if you need this password to be saved in your .ilv file while saving your layer. If you don't want your password to be saved, just set this parameter to 0. |
| IlvObjectSDOLayer::IlvObjectSDOLayer | ( | IlvSDOTileLoader * | sdoTileLoader, |
| IlvTileCache * | cache, | ||
| const char * | password = 0 |
||
| ) |
Initializes a new instance of IlvObjectSDOLayer to load data by using the specified tile loader.
| sdoTileLoader | The tile loader that generates the SQL queries and defines the size of the tiling grid. This tile loader is owned by the layer so that its destructor deletes also the tile loader. |
| cache | The object that manages the release of invisible tiles. |
| password | The password the user gives in order to get connected to the Database. This parameter is also necessary to the IldNewDbms() function which creates an instance of IldDbms. You can set this parameter for the user's password if you need this password to be saved in your .ilv file while saving your layer. If you don't want your password to be saved, just set this parameter to 0. |
| IlBoolean IlvObjectSDOLayer::isAttachingAttributes | ( | ) | const |
Indicates if the attributes read from the SDO layer are attached to the IlvGraphic objects.
IlTrue if the attributes read from the SDO layer are attached to the IlvGraphic objects, IlFalse otherwise. | void IlvObjectSDOLayer::setAttachingAttributes | ( | IlBoolean | attachAttributes | ) |
Specifies whether the attributes read from the SDO layer should be attached to the IlvGraphic objects as IlvFeatureAttributeProperty.
By default, the attributes are not attached to the graphic objects.
The attribute of the IlvGraphic can be retreived this way:
IlvFeatureAttributeProperty* ap = (IlvFeatureAttributeProperty*)
theGraphic->getNamedProperty(IlvFeatureAttributeProperty::GetName());
| attachAttributes | If IlTrue, the attributes are attached to the graphic objects. |
