Method Detail

setAlwaysCreate

public void setAlwaysCreate(boolean alwaysCreate)

Set to true when an update of an object should create the object if it does not yet exist.

Parameters:

alwaysCreate - set to true to create non-existing object when updating one, false otherwise

setUsageType

public void setUsageType(GluonCloudObjectDataWriterImpl.UsageType usageType)

setListIdentifier

public void setListIdentifier(String listIdentifier)

createRestDataSource

protected RestDataSource createRestDataSource()
                                       throws IOException

Overrides:

createRestDataSource in class GluonCloudObjectDataReaderImpl<T>

Throws:

IOException

writeObject

public Optional<T> writeObject(T object)
                        throws IOException

Description copied from interface: ObjectDataWriter

Writes the object and optionally returns one. The actual method that converts the object into serialized data and the source where this data is written to is completely left to the implementation. This method is called by DataProvider.storeObject(Object, ObjectDataWriter) to initiate the actual write process. The returned object will be set on the final GluonObservableObject that is provided by this writer's ObjectDataWriter.newGluonObservableObject() method. The returned object can be the same as the provided object or it can be a completely new object. An empty Optional can be returned as well, which is the same as returning the provided object.

Specified by:

writeObject in interface ObjectDataWriter<T>

Parameters:

object - the object to write

Returns:

the object that will ultimately be set on the GluonObservableObject

Throws:

IOException - when an exception occurred during the write process

removeObject

public Optional<T> removeObject(GluonObservableObject<T> observable)
                         throws IOException

Description copied from interface: ObjectDataRemover

Removes the object and optionally returns an object. The actual method that removes the object is completely left to the implementation. This method is called by DataProvider.removeObject(GluonObservableObject, ObjectDataRemover) to initiate the actual removal process. If this method returns a non-empty Optional, the object that is contained in the Optional will be set on the provided observable object. Otherwise, the value of the observable object will be set to null. When the remove operation completed successfully, the state of the provided observable will be set to ConnectState.REMOVED.

Specified by:

removeObject in interface ObjectDataRemover<T>

Parameters:

observable - the observable object that needs to be removed

Returns:

an optional containing an object that will ultimately be set on the provided GluonObservableObject

Throws:

IOException - when an exception occurred during the removal process
