 package com.amazonaws.services.cloudformation.model;
 

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

 
 public class ParameterConstraints implements SerializableCloneable {

    
A list of values that are permitted for a parameter.
 
A list of values that are permitted for a parameter.

Returns:
A list of values that are permitted for a parameter.

         }
         return ;
     }
    
    
A list of values that are permitted for a parameter.

Parameters:
allowedValues A list of values that are permitted for a parameter.
 
     public void setAllowedValues(java.util.Collection<StringallowedValues) {

A list of values that are permitted for a parameter.

NOTE: This method appends the values to the existing list (if any). Use setAllowedValues(java.util.Collection) or withAllowedValues(java.util.Collection) if you want to override the existing values.

Returns a reference to this object so that method calls can be chained together.

Parameters:
allowedValues A list of values that are permitted for a parameter.
Returns:
A reference to this updated object so that method calls can be chained together.
