Initialize aggregate processing for case operation
Source position: fpexprpars.pp line 287
public procedure TCaseOperation.InitAggregate; override; |
The InitAggregate method initializes aggregate processing for the case operation node. It prepares the case operation for aggregate calculations by initializing any aggregate functions used within the case branches.
The initialization process ensures that all child nodes that contain aggregate functions are properly set up for aggregate processing, allowing the case operation to participate correctly in aggregate expression evaluation.
