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 }); =head3 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->ConditionExpression =head1 DESCRIPTION Represents a request to perform an C operation. =head1 ATTRIBUTES =head2 ConditionExpression => Str A condition that must be satisfied in order for a conditional update to succeed. =head2 ExpressionAttributeNames => L One or more substitution tokens for attribute names in an expression. =head2 ExpressionAttributeValues => L One or more values that can be substituted in an expression. =head2 B Key => L The primary key of the item to be updated. Each element consists of an attribute name and a value for that attribute. =head2 ReturnValuesOnConditionCheckFailure => Str Use C to get the item attributes if the C condition fails. For C, the valid values are: NONE, ALL_OLD, UPDATED_OLD, ALL_NEW, UPDATED_NEW. =head2 B TableName => Str Name of the table for the C request. =head2 B UpdateExpression => Str An expression that defines one or more attributes to be updated, the action to be performed on them, and new value(s) for them. =head1 SEE ALSO This class forms part of L, describing an object used in L =head1 BUGS and CONTRIBUTIONS The source code is located here: L Please report bugs to: L =cut
