public int lockFeatures() throws IOException
FeatureLocking
The method does not prevent addFeatures() from being used (we could add a lockDataSource() method if this functionality is required.

To implement WFS parcial Locking retrieve your features with a query operation first before trying to lock them individually. If you are not into WFS please don't ask what parcial locking is.

filter
- Filter describing the features to lock
IOException
- Thrown if anything goes wrongpublic void setFeatureLock(FeatureLock lock)
FeatureLocking
lock
.
This in in keeping with the stateful spirit of DataSource in which operations are against the "current" transaction. If a FeatureLock is not provided lock operations will only be applicable for the current transaction (they will expire on the next commit or rollback).
That is lockFeatures() operations will:
Calling this method with setFeatureLock( FeatureLock.TRANSACTION
)
will revert to per transaction operation.
This design allows for the following:
