Paws::DynamoDB::Update
USAGE
This class represents one of two things:
Arguments in a call to a service
Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.
As an example, if Att1 is expected to be a Paws::DynamoDB::Update object:
$service_obj->Method(Att1 => { ConditionExpression => $value, ..., UpdateExpression => $value });Results returned from an API call
Use accessors for each attribute. If Att1 is expected to be an Paws::DynamoDB::Update object:
$result = $service_obj->Method(...);
$result->Att1->ConditionExpressionDESCRIPTION
Represents a request to perform an UpdateItem operation.
