Stephen Colebourne reopened COLLECTIONS-182: -------------------------------------------- Reconsider for generics version > [collections] Change CollectionUtils.forAllDo to return the Closure > ------------------------------------------------------------------- > > Key: COLLECTIONS-182 > URL: http://issues.apache.org/jira/browse/COLLECTIONS-182 > Project: Commons Collections > Issue Type: Improvement > Affects Versions: 3.1 > Environment: Operating System: All > Platform: All > Reporter: Jim Cakalic > Priority: Minor > Fix For: Generics > > > I frequently use CollectionUtils.forAllDo with a Closure that determines some > kind of aggregate value across the members of the Collection. For example, and > this is entirely manufactured, say I have an Order with a collection of > LineItems. Order might use a SumClosure to count the number of actual items > (not > LineItem objects) on the Order or to compute the sum of the LineItems cost. It > would be convenient in these cases if I could use the return of forAllDo to > chain method calls like this: > public BigDecimal getTotal() { > return CollectionUtils.forAllDo(lineItems, new > SumTotalClosure()).total(); > } > As it is, I have to make do with the somewhat less compact: > public BigDecimal getTotal() { > SumTotalClosure closure = new SumTotalClosure(); > CollectionUtils.forAllDo(lineItems, closure); > return closure.total(); > } > Thanks for considering it. > Regards, > Jim Cakalic -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
