    • updateOrInsertMetadata

      public boolean updateOrInsertMetadata(org.gvsig.fmap.dal.feature.FeatureAttributeDescriptor geomDescriptor)
      Updates the USER_SDO_GEOM_METADATA table or inserts if an entry is not found for the layer. The update is only performed if the new layer extent is bigger than current one.
      Parameters:
      geomDescriptor -
      Returns:
      true if the metadata table was changed, false otherwise

    • updateUserMetadata

      public boolean updateUserMetadata(List<OracleDimensionMetadata> dimensions, String geomColumnName, int srid)
      Updates layer metatada on USER_SDO_GEOM_METADATA table
      Parameters:
      dimensions -
      geomColumnName -
      srid -
      Returns:
      Returns true if the layer record exists on the table and has been correctly updated, false otherwise

    • insertUserMetadata

      public boolean insertUserMetadata(List<OracleDimensionMetadata> dimensions, String geomColumnName, int srid)
      Inserts layer metatada on USER_SDO_GEOM_METADATA table
      Parameters:
      dimensions -
      geomColumnName -
      srid -
      Returns:
      Returns true if the layer record has been correctly inserted, false otherwise

    • getEnvelope

    • updateDimensions

      protected boolean updateDimensions(List<OracleDimensionMetadata> dimensions, org.gvsig.fmap.geom.primitive.Envelope newEnvelope)
      Updates the dimension definition using the provided envelope. The update is only performed if the new layer extent is bigger than the one defined on dimension metadata.
      Parameters:
      dimensions -
      newEnvelope -
      Returns:
      true if the definition was updated, false otherwise

    • fetchDimensionMetadata

      protected List<OracleDimensionMetadata> fetchDimensionMetadata()
      Fetches dimensions from ALL_SDO_GEOM_METADATA table and updates the layer envelope using the provided one
      Returns:

    • createOrRebuildSpatialIndex
