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::CloudFormation::Parameter object:

  $service_obj->Method(Att1 => { ParameterKey => $value, ..., UsePreviousValue => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::CloudFormation::Parameter object:

  $result = $service_obj->Method(...);


The Parameter data type.


ParameterKey => Str

  The key associated with the parameter. If you don't specify a key and
value for a particular parameter, AWS CloudFormation uses the default
value that is specified in your template.

ParameterValue => Str

  The input value associated with the parameter.

ResolvedValue => Str

  Read-only. The value that corresponds to a Systems Manager parameter
key. This field is returned only for C<SSM> parameter types
in the template.

UsePreviousValue => Bool

  During a stack update, use the existing parameter value that the stack
is using for a given parameter key. If you specify C<true>, do not
specify a parameter value.


This class forms part of Paws, describing an object used in Paws::CloudFormation
