Method Detail

getDataManager

protected DataManager getDataManager()

getDataContext

@Nullable
public DataContext getDataContext()

Description copied from interface: DataLoader

Returns data context. If the data context is set, all loaded instance will be merged into it.

Specified by:

getDataContext in interface DataLoader

setDataContext

public void setDataContext(DataContext dataContext)

Description copied from interface: DataLoader

Sets the data context for the loader. If the data context is set, all loaded instance will be merged into it.

Specified by:

setDataContext in interface DataLoader

load

Description copied from interface: DataLoader

Loads data to the connected container.

Specified by:

load in interface DataLoader

createLoadContext

public ValueLoadContext createLoadContext()

Description copied from interface: KeyValueInstanceLoader

Returns ValueLoadContext which is created by the parameters of this loader. The ValueLoadContext can be used with DataManager to load data by the same conditions.

Specified by:

createLoadContext in interface KeyValueInstanceLoader
