public static Environment toProto(java.util.Map<java.lang.String,java.lang.String> environmentMap)

Returns a Protobuf representation of the provided environment Map. This is the inverse of toMap(Environment).

withEnvVar

public static Environment withEnvVar(Environment environment,
                                     java.lang.String key,
                                     java.lang.String value)
