static bool matchGeneric(hash< auto > record, *hash< auto > where_cond)
Checks if the current record matches the search criteria.

auto doMemberGate(string key)
Returns the value of the given field in the current record, if the iterator is valid.
*hash< string, AbstractDataField > getRecordType()
Returns the record description, if available.
bool supportsBulkApi()
Returns True if the iterator supports bulk operation.

abstract hash< auto > getValue()
returns a single record if the iterator is valid
*AbstractDataProviderBulkRecordInterface getBulkApi()
Returns the bulk data interface if supported.
static bool matchGenericValue(auto expects, auto val)
Match a single value.
