It checks if a provided `oldId` matches any of the block's variable IDs. If a match is found, the variable's ID is updated to the provided `newId`. The method takes two string parameters: `oldId` (the original ID) and `newId` (the updated ID) and does not return any value. This method ensures variable consistency across the block during a rename operation.\n"]]
