Amazonka.CloudFormation.Types.ParameterConstraints

Description

Synopsis

data ParameterConstraints = ParameterConstraints' {
- allowedValues :: Maybe [Text]
}
newParameterConstraints :: ParameterConstraints
parameterConstraints_allowedValues :: Lens' ParameterConstraints (Maybe [Text])

Documentation

data ParameterConstraints Source #

A set of criteria that CloudFormation uses to validate parameter values. Although other constraints might be defined in the stack template, CloudFormation returns only the AllowedValues property.

See: newParameterConstraints smart constructor.

Constructors

ParameterConstraints'
Fields allowedValues :: Maybe [Text] A list of values that are permitted for a parameter.

newParameterConstraints :: ParameterConstraints Source #

Create a value of ParameterConstraints with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:allowedValues:ParameterConstraints', parameterConstraints_allowedValues - A list of values that are permitted for a parameter.

parameterConstraints_allowedValues :: Lens' ParameterConstraints (Maybe [Text]) Source #

A list of values that are permitted for a parameter.
