public SsmLookup(com.amazonaws.services.simplesystemsmanagement.AWSSimpleSystemsManagement ssm,
                 boolean strict,

Constructor.

Parameters:

ssm - A configured AWSSimpleSystemsManagement client to use for parameter value requests.

strict - true if lookups should throw an UndefinedEnvironmentVariableException when no value is found

namespacePrefix - A prefix to prepend to variable names when determining the parameter key.

This is mostly useful for re-using a variable name across multiple environments
