Detailed Description

Implements load-on-demand layer for an Oracle Spatial data source.

Library: ilvdbmaps

Constructor & Destructor Documentation

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,
		const char *	password = 0
	)

Initializes an 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.

Parameters

mapAdapter	The map adapter used by the layer.
dbms	The IldDbms 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 IlvMapFeaturId. 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 an instance of IlvObjectSDOLayer to load data by using the specified tile loader.

Parameters

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.

Member Function Documentation

IlBoolean IlvObjectSDOLayer::isAttachingAttributes

(

)

const

Returns IlTrue if the attributes read from the SDO layer are attached to the IlvGraphic objects.

Returns

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());

Parameters

attachAttributes

If set to IlTrue, the attributes are attached to the graphic objects.
