NameLN()
Create an empty NameLN, to be filled in from the log. |
|
NameLN(DatabaseId id,
EnvironmentImpl envImpl,
boolean replicate)
In the ideal world, we'd have a base LN class so that this NameLN doesn't have a superfluous data field, but we want to optimize the LN class for size and speed right now. |
