Interface TxnId

All Known Implementing Classes:

TxnIdSimple, TxnIdUuid

public interface TxnId

TxnId is a identifier for a transaction. A component in a transaction can use it as a unique key. The TxnId

• must be unique across a JVM run
• unique across JVm runs if used as a persistent name
• Must provide value equality semantics (two TxnId are .equals if

It is preferrable that the TxnId is global unique over time and space.

long	runtime() A long that is a subset, or all or, the bytes.

Method Detail

hashCode

int hashCode()

Overrides:

hashCode in class Object

equals

boolean equals(Object other)

Overrides:

equals in class Object

name

String name()

bytes

byte[] bytes()

runtime

long runtime()

A long that is a subset, or all or, the bytes. This should be unique for the lifetime of the transaction and ideally unique per system instance. It is not a persistent record of a transaction, it is for a transaction identifier in running code. ("system" maybe larger than on e JVM).
