Class OntimizePointProvider

java.lang.Object
  com.ontimize.util.gis.server.dataproviders.BasicOntimizeDataProvider
      com.ontimize.util.gis.server.dataproviders.OntimizePointProvider

All Implemented Interfaces:

IDataAccess, IDataProvider

public class OntimizePointProvider
extends BasicOntimizeDataProvider
implements IDataAccess

Points vectorial data provider. It uses an Ontimize entities without a binary column to save geograhpic data.
It only needs two columns indicating the x and y positions (long/lat).

Xml definition parameters:

Name	Description	Required
entity_name	Related Ontimize entity name	Yes
keys	Primary keys entity columns.Separated by ";"	Yes
data_columns	Columns containing other layer data (separated by ";"). This parameter will contain extra data fields that may be useful on gis data display.	No
bbox_columns	List of columns containing the bounding box of the layer data. For points layer: x position and y position. For lines and polygons: minmum x, maximum x, minimumy and maximum y.	Yes

Sample definition code:

<DataProvider
    class="com.ontimize.util.gis.server.dataproviders.OntimizePointsProvider"
        type="vectorial">
        <Attribute name="entity_name" value="ELocations" />
        <Attribute name="keys" value="locationid" />
        <Attribute name="bbox_columns" value="posx;posy" />
        <Attribute name="geometry_type" value="point" />
 </DataProvider>

Method Detail

initProvider

public void initProvider(java.util.Hashtable<java.lang.String,java.lang.Object> parameters)

Specified by:

initProvider in interface IDataProvider

Overrides:

initProvider in class BasicOntimizeDataProvider

query

public java.lang.Object query(java.lang.Object keysValues,
                              java.lang.Object attributes,
                              int sessionId)
                       throws java.lang.Exception

Description copied from interface: IDataProvider

This method must implement a standard query operation returning the set of data that matches the conditions specified by the keysValues parameter. The attributes defines which attributes (or columns if data is obtained from a database) must be recovered, and keysValues specifies which set of records must be recovered.

Specified by:

query in interface IDataProvider

Overrides:

query in class BasicOntimizeDataProvider

Parameters:

keysValues - Identifiers for the data

attributes - Data attributes to query

sessionId - Session Id for this user

Returns:

Requested data

Throws:

java.lang.Exception

update

public void update(java.lang.Object keysValues,
                   java.lang.Object attributesValues,
                   int sessionId)
            throws java.lang.Exception

Description copied from interface: IDataAccess

This method must implement a standard update operation with the data specified in attributesValues over the set of records defined by keysValues. So, only the records that comply with the conditions specified by keysValues will be updated to the new values specified by attributesValues.

Specified by:

update in interface IDataAccess

Overrides:

update in class BasicOntimizeDataProvider

Parameters:

keysValues - The conditions that the records to be updated must fulfill

attributesValues - The data for updating the records to

sessionId - Session Id for this user

Throws:

java.lang.Exception
