DbDataProvider::DbTableBulkRecordInterface::constructor | ( | int | block_size, |
AbstractTable | table, | ||
*hash< auto > | where_cond, | ||
*hash< auto > | search_options | ||
) |
creates the iterator
block_size | the number of records in a read block; must be a positive number |
table | the table to iteratate |
where_cond | the search criteria; will be processed by processFieldValues() |
search_options | search options; assumed to have already been processed for validity before this call |
Returns the record description, if available.
Returns a hash of lists according to the block size.
INVALID-ITERATOR | the iterator is not pointing at a valid element |
