Detailed Description

A ReadCondition is a specialized Condition associated with a DataReader.

The trigger_value is driven by the data available in the associated DataReader. A ReadCondition is obtained by calling the DataReader_create_readcondition() function. When the ReadCondition is no longer needed, it should be destroyed by a call to DataReader_delete_readcondition().
