Interface HGTransaction

All Known Implementing Classes:

TransactionBDBImpl, VanillaTransaction

public interface HGTransaction

Represents a transaction object. The interface is minimalistic on purpose, exposing only the two essential operations one can do one a transaction.

Each transaction can carry an arbitrary set of attributes along with it. This is useful for attaching contextual information to transactions without intruding to otherwise simple APIs. When a transaction is committed or aborted, all attributes are removed.
