TCustomPropertyStorage.StorageNeeded procedure
Ensures that the storage mechanism for the container is available.
Declaration
procedure StorageNeeded(ReadOnly: Boolean); virtualArguments
ReadOnly | True if write access is disabled for the property store. False if write access is allowed. |
Description
StorageNeeded is a method used to ensure that the underlying
storage mechanism for the container has been allocated and configured.
StorageNeeded has an empty implementation in
TCustomPropertyStorage. It must be overridden in a descendent
class to use the format and access mechanism needed.
The ReadOnly argument indicates whether write access is enabled
for the storage. In general, the Save method requires write access
and the Restore method does not.
