generateTransactGetItem

public TransactGetItem generateTransactGetItem()

This method is used by the internal transactGetItems operation to generate a transact read item used in the call to DynamoDb. Each TransactableReadOperation, such as GetItem, creates a transact get item corresponding to that operation. The method should only be called from the transactGetItems operation and should not be used for other purposes.

Returns:

A TransactGetItem that will be used in calls to DynamoDb.
