Re: [Pharo-users] transactions on pharo objects

Hi,

is there some library or approach how to do transactions in pharo? And I don't mean database transactions, but directly in memory on Pharo objects... e.g.

p := Person new.

transaction do: [ p name: 'Nobody'. p age: 70. ] on: Error do: [ transaction rollback. ].

self assert: p name equals: 'Nobody'. self assert: p age equals: 70.

transaction do: [ p name: 'Somebody'. p age: 1 / 0. ] on: Error do: [ transaction rollback. ].

self assert: p name equals: 'Nobody'. self assert: p age equals: 70.

Any pointers appreciated.

Should this work image wide or per process? Norbert
