Member Function Documentation

addEntity()

virtual bool TSLSLMEntityStoreHandler::addEntity ( const TSLEntity * entity )

pure virtual

Called when an entity should be added to the store.

Parameters

entity

The new entity.

modifyEntity()

virtual bool TSLSLMEntityStoreHandler::modifyEntity ( const TSLEntity * entity )

pure virtual

Called when an entity should be updated in the store.

Parameters

entity

The modified entity.

onBeginImport()

virtual bool TSLSLMEntityStoreHandler::onBeginImport ( const TSLDataHandler * dataHandler )

pure virtual

Called at the start of the data import process.

Parameters

dataHandler

The data handler associated with the imported entities.

Clients should return a value of true to allow the SeamlessLayer manager to perform the import of data. A return value of false will force the onEndImport() method to be called immediately.

onEndImport()

virtual bool TSLSLMEntityStoreHandler::onEndImport ( bool importSuccess )

pure virtual

Called at the end of the data import process.

Parameters

importSuccess

A bool flag which indicates whether the main import process was successful.

A return value of false signifies that the derived-class object has encountered an error in its tidy-up phase.

removeEntity()

virtual bool TSLSLMEntityStoreHandler::removeEntity ( const TSLEntity * entity )

pure virtual

Called when an entity should be removed from the store.

Parameters

entity

The entity to remove.
