java - Convert FastSet to Array of String -


i have set: set<string> tmpset = fastset.newinstance();

when follow question: how convert set string[]?

and same: string[] strarrstrings = includefeatureids.toarray(new string[0]);

and have exception:

exception: java.lang.illegalargumentexception message: error running script @ location [component://order/webapp/ordermgr/web-inf/actions/entry/catalog/keywordsearch.groovy]: java.lang.unsupportedoperationexception: destination array small ---- cause --------------------------------------------------------------------- exception: java.lang.unsupportedoperationexception message: destination array small ---- stack trace --------------------------------------------------------------- java.lang.unsupportedoperationexception: destination array small javolution.util.fastcollection.toarray(fastcollection.java:351)

so now, have code as:

for (fastset.record r = tmpset.head(), end = tmpset.tail(); (r = r.getnext()) != end;) {          // copy 1 one element string[]        }

my question: there anyway(or utility) convert fastset string[]?

thank :-)

see also:

see fastcollection#toarray(t[])

unlike standard collection, method not try resize array

so have make array right size. use

includefeatureids.toarray(new string[includefeatureids.size()])

instead of

includefeatureids.toarray(new string[0])
