Detailed Description

Defines the record iterator class for Table-based iterators.

Member Function Documentation

RemoteDbDataProvider::RemoteDbSelectBulkRecordInterface::constructor	(	DbRemoteBase	remote,
		int	block_size,
		*hash< auto >	where_cond,
		*hash< auto >	search_options
	)

creates the iterator

Parameters

remote	the remote connection
block_size	the number of records in a read block; must be a positive number; will override any `block` value in `search_options`
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

hash< string, list< auto > > RemoteDbDataProvider::RemoteDbSelectBulkRecordInterface::getValueImpl ( )

private

Returns a hash of lists according to the block size.

Exceptions

INVALID-ITERATOR the iterator is not pointing at a valid element

Note: This call moves the internal record pointer forward, therefore multiple calls of this methods will return different results as long as data is available
