Class ReplaceAction

java.lang.Object

com.kingsrook.qqq.backend.core.actions.AbstractQActionFunction<ReplaceInput,ReplaceOutput>

com.kingsrook.qqq.backend.core.actions.tables.ReplaceAction

public class ReplaceAction
extends AbstractQActionFunction<ReplaceInput,ReplaceOutput>

Action to do a "replace" - e.g: Update rows with unique-key values that are already in the table; insert rows whose unique keys weren't already in the table, and delete rows that weren't in the input (all based on a UniqueKey that's part of the input) Note - the filter in the ReplaceInput - its role is to limit what rows are potentially deleted. e.g., if you have a table that's segmented, and you're only replacing a particular segment of it (say, for 1 client), then you pass in a filter that finds rows matching that segment. See Test for example.
