示例1: walkCompIdxs
// walkCompIdxs walks the table of compound indexes in the store. If `endsWith`
// is provided, this will only walk over compound indexes which match
// Kind, Ancestor, and whose SortBy has `endsWith.SortBy` as a suffix.
func walkCompIdxs(store *memStore, endsWith *ds.IndexDefinition, cb func(*ds.IndexDefinition) bool) {
idxColl := store.GetCollection("idx")
if idxColl == nil {
return
}
itrDef := iterDefinition{c: idxColl}
if endsWith != nil {
full := serialize.ToBytes(*endsWith.Flip())
// chop off the null terminating byte
itrDef.prefix = full[:len(full)-1]
}
it := itrDef.mkIter()
defer it.stop()
for !it.stopped {
