| Method Summary | |
| Set | addFeatures(FeatureCollection collection)
Adds all features from the passed feature collection to the datasource.
Parameters:
collection - The collection of features to add. | | Transaction | getTransaction()
Used to access the Transaction this DataSource is currently opperating
against. | | void | modifyFeatures(AttributeType[] type, Object[] value, Filter filter)
Modifies the passed attribute types with the passed objects in all
features that correspond to the passed OGS filter. | | void | modifyFeatures(AttributeType type, Object value, Filter filter)
Modifies the passed attribute types with the passed objects in all
features that correspond to the passed OGS filter. | | void | removeFeatures(Filter filter)
Removes all of the features specificed by the passed filter from the
collection. | | void | setFeatures(FeatureReader reader)
Deletes the all the current Features of this datasource and adds the new
collection. | | void | setTransaction(Transaction transaction)
Provides a transaction for commit/rollback control of this FeatureStore.
This method operates as a replacement for setAutoCommitMode. |
| addFeatures | | Set addFeatures(FeatureCollection collection) throws IOException(Code) | | Adds all features from the passed feature collection to the datasource.
Parameters:
collection - The collection of features to add. the FeatureIds of the newly added features.
throws:
IOException - if anything goes wrong. |
| getTransaction | | Transaction getTransaction()(Code) | | Used to access the Transaction this DataSource is currently opperating
against.
Example Use: adding features to a road DataSource
Transaction t = roads.getTransaction();
try{
roads.addFeatures( features );
roads.getTransaction().commit();
}
catch( IOException erp ){
//something went wrong;
roads.getTransaction().rollback();
}
Transaction in use, or Transaction.AUTO_COMMIT |
| modifyFeatures | | void modifyFeatures(AttributeType[] type, Object[] value, Filter filter) throws IOException(Code) | | Modifies the passed attribute types with the passed objects in all
features that correspond to the passed OGS filter.
Parameters:
type - The attributes to modify.
Parameters:
value - The values to put in the attribute types.
Parameters:
filter - An OGC filter to note which attributes to modify.
throws:
IOException - if the attribute and object arrays are not eqaullength, if the object types do not match the attribute types,or if there are backend errors. |
| modifyFeatures | | void modifyFeatures(AttributeType type, Object value, Filter filter) throws IOException(Code) | | Modifies the passed attribute types with the passed objects in all
features that correspond to the passed OGS filter. A convenience
method for single attribute modifications.
Parameters:
type - The attributes to modify.
Parameters:
value - The values to put in the attribute types.
Parameters:
filter - An OGC filter to note which attributes to modify.
throws:
IOException - If modificaton is not supported, if the object typedo not match the attribute type. |
| removeFeatures | | void removeFeatures(Filter filter) throws IOException(Code) | | Removes all of the features specificed by the passed filter from the
collection.
Parameters:
filter - An OpenGIS filter; specifies which features to remove.
throws:
IOException - If anything goes wrong. |
| setFeatures | | void setFeatures(FeatureReader reader) throws IOException(Code) | | Deletes the all the current Features of this datasource and adds the new
collection. Primarily used as a convenience method for file
datasources.
Parameters:
reader - - the collection to be written
throws:
IOException - if there are any datasource errors. |
| setTransaction | | void setTransaction(Transaction transaction)(Code) | | Provides a transaction for commit/rollback control of this FeatureStore.
This method operates as a replacement for setAutoCommitMode. When a
transaction is provided you are no longer automatically committing.
In order to return to AutoCommit mode supply the Transaction.AUTO_COMMIT
to this method. Since this represents a return to AutoCommit mode the
previous Transaction will be commited.
Parameters:
transaction - DOCUMENT ME! |
