Class IlvObjectSDOLayerMetaData

java.lang.Object

ilog.views.maps.format.oracle.objectmodel.IlvObjectSDOLayerMetaData

All Implemented Interfaces:

IlvPersistentObject

public class IlvObjectSDOLayerMetaData
extends Object
implements IlvPersistentObject

This class represents the metadata information for an Oracle Spatial layer. This metadata is composed of the table name, or the name of the layer, the column name, or the name of the column containing the geometries, the diminfo represented by IlvObjectSDODimElement, and an optional SRID number. This information is contained in the (XXX_)SDO_GEOM_METADATA view, XXX being ALL, DBA or USER.
The role of the metadata is to store general information (such as the extent) related to the SDO layer and its geometries.
To get a metadata from the database, you can use the IlvObjectSDOUtil.GetLayerMetaData(java.sql.Connection, java.lang.String, java.lang.String, java.lang.String, java.lang.String) method.
For more information about the metadata structure, please refer to the Oracle Spatial documentation.

Constructor Detail

IlvObjectSDOLayerMetaData

public IlvObjectSDOLayerMetaData(String ownerName,
                                 String tableName,
                                 String geometryColumnName,
                                 Long srid,
                                 IlvObjectSDODimElement[] dimElements)

Constructs a new metadata. You can build a metadata by using directly this constructor, or by using the IlvObjectSDOUtil.GetLayerMetaData(java.sql.Connection, java.lang.String, java.lang.String, java.lang.String, java.lang.String) method.

Parameters:

ownerName - The name of the owner of the metadata. For instance, if the metadata has been built by means of the IlvObjectSDOUtil.GetLayerMetaData(java.sql.Connection, java.lang.String, java.lang.String, java.lang.String, java.lang.String) method by querying the ALL_SDO_GEOM_METADATA view, then this name corresponds to the OWNER column of the view.

tableName - The name of the SDO layer table.

geometryColumnName - The name of the column containing the geometries objects.

srid - The SDO_SRID corresponding to the Oracle Spatial Reference System. If you are using a database whose version is 8.1.5-, then pass this argument as null.

dimElements - The dim elements.

IlvObjectSDOLayerMetaData

public IlvObjectSDOLayerMetaData(IlvInputStream stream)

Parameters:

stream - The stream.

Throws:

IlvReadFileException
