Method Details

setFeatureLock
Description copied from interface:FeatureLocking
All locking operations will operate against the providedlock
.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:
- Be recorded against the provided FeatureLock.
- Be recorded against the current transaction if no FeatureLock is provided.
Calling this method with
setFeatureLock( FeatureLock.TRANSACTION )
will revert to per transaction operation.This design allows for the following:
- cross DataSource FeatureLock usage
- not having pass in the same FeatureLock object multiple times
- Specified by:
setFeatureLock
in interfaceFeatureLocking<SimpleFeatureType,
SimpleFeature> - Parameters:
lock
- FeatureLock configuration including authorization and requested duration
-
lockFeatures
Description copied from interface:FeatureLocking
FeatureLock features described by Query.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.
- Specified by:
lockFeatures
in interfaceFeatureLocking<SimpleFeatureType,
SimpleFeature> - Parameters:
query
- Query describing the features to lock- Returns:
- Number of features locked
- Throws:
IOException
- Thrown if anything goes wrong

in interfaceFeatureLocking<SimpleFeatureType,
SimpleFeature> - Parameters:
filter
- Filter describing the features to lock- Returns:

-
lockFeatures
Description copied from interface:FeatureLocking
FeatureLock all Features.The method does not prevent addFeatures() from being used (we could add a lockDataSource() method if this functionality is required.
- Specified by:
lockFeatures
in interfaceFeatureLocking<SimpleFeatureType,
SimpleFeature> - Returns:
- Number of Features locked by this opperation
- Throws:
IOException
-
unLockFeatures
Description copied from interface:FeatureLocking
Unlocks all Features.Authorization must be provided prior before calling this method.
void releaseLock( String lockId, LockingDataSource ds ){ ds.setAuthorization( "LOCK534" ); ds.unLockFeatures(); }
- Specified by:
unLockFeatures
in interfaceFeatureLocking<SimpleFeatureType,
SimpleFeature> - Throws:
IOException
-
unLockFeatures
Description copied from interface:FeatureLocking
Unlock Features denoted by provided filter.Authorization must be provided prior before calling this method.
- Specified by:
unLockFeatures
in interfaceFeatureLocking<SimpleFeatureType,
SimpleFeature> - Throws:
IOException
-
unLockFeatures
Description copied from interface:FeatureLocking
Unlock Features denoted by provided query.Authorization must be provided prior before calling this method.
- Specified by:
unLockFeatures
in interfaceFeatureLocking<SimpleFeatureType,
SimpleFeature> - Parameters:
query
- Specifies fatures to unlock- Throws:
