## Member Function Documentation

## constructor()

DataProvider::AbstractDataProviderBulkRecordInterface::constructor | ( | int | block_size | ) |

Creates the object.

Parameters

  block_size | the record block size for the iterator

## getValue()

*hash<string, list<auto> > DataProvider::AbstractDataProviderBulkRecordInterface::getValue | ( |  | ) |

Returns a hash of lists according to the block size or NOTHING if no more data is available.

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

## getValueImpl()

abstract hash<string, list<auto> > DataProvider::AbstractDataProviderBulkRecordInterface::getValueImpl | ( |  | ) |

protectedpure virtual

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

Implemented in DataProvider::DefaultBulkRecordIterface.
