Initialize minimum aggregation
Source position: fpexprpars.pp line 660
public procedure TAggregateMin.InitAggregate; override; |
The InitAggregate method initializes the minimum aggregate for a new aggregation cycle. It sets up the internal state needed to track the minimum value across multiple value updates.
The method sets an internal flag, indicating that the next value processed will be the first value in the aggregation sequence. It also prepares any internal storage needed for the minimum calculation.
The InitAggregate method must be called before starting a new aggregation cycle to ensure proper initialization of the aggregate state.
