| 24 | /** | |
| 25 | * The ExecutionOptions contain a set of options that can be passed to the KRMS | |
| 26 | * engine to control certain aspects related to it's execution. It supports | |
| 27 | * two different types of options: | |
| 28 | * | |
| 29 | * <ol> | |
| 30 | * <li>flags - a map of pre-defined boolean {@link ExecutionFlag} instances which can be either true or false</li> | |
| 31 | * <li>options - a general-purpose map of Strings which can be used to define optinos that have non-boolen values</li> | |
| 32 | * </ol> | |
| 33 | * | |
| 34 | * <p>The options map can be used to pass user-defined or provider-specific options. The ExecutionOptions are made | |
| 35 | * available as part of the {@link ExecutionEnvironment} during engine execution. | |
| 36 | * | |
| 37 | * <p>Instances of ExecutionOptions are not safe for use by multiple threads. | |
