Constructor Summary
public  Transaction(WFS wfs, Data catalog, ApplicationContext context)
    

Method Summary
public  voidabort(TransactionType request)
    
protected  TransactionResponseTypeexecute(TransactionType request)
     Execute Transaction request.

The results of this opperation are stored for use by writeTo:

  • transaction: used by abort & writeTo to commit/rollback
  • request: used for users getHandle information to report errors
  • stores: FeatureStores required for Transaction
  • failures: List of failures produced

Because we are using geotools2 locking facilities our modification will simply fail with IOException if we have not provided proper authorization.

The specification allows a WFS to implement PARTIAL sucess if it is unable to rollback all the requested changes.

logger



catalog
protected Data catalog(Code)
The catalog



filterFactory
protected FilterFactory filterFactory(Code)
Filter factory

Constructor Detail
Transaction
public Transaction(WFS wfs, Data catalog, ApplicationContext context)(Code)




Method Detail
abort
public void abort(TransactionType request)(Code)



execute
protected TransactionResponseType execute(TransactionType request) throws Exception(Code)
Execute Transaction request.

The results of this opperation are stored for use by writeTo:

  • transaction: used by abort & writeTo to commit/rollback
  • request: used for users getHandle information to report errors
  • stores: FeatureStores required for Transaction
  • failures: List of failures produced

Because we are using geotools2 locking facilities our modification will simply fail with IOException if we have not provided proper authorization.

The specification allows a WFS to implement PARTIAL sucess if it is unable to rollback all the requested changes. This implementation is able to offer full Rollback support and will not require the use of PARTIAL success.
