Examples of org.openengsb.core.workflow.api.RuleManager

org.openengsb.core.workflow.api.RuleManager
The RuleManager serves as an abstraction to modify the rulebase used by the workflow engine. It offers methods to modify the rulebase and makes sure that the changes are propagated to the WorkflowService. The elements in a rulebase are identified using the {@link RuleBaseElementId} class.Declaration of imports and global variables are handled explicitly. Also they are the same in all packages, so they are only saved once. The assignment of values to the globals is handled by the WorkflowService. Note: When adding a new rule or function to the rulebase, make sure that all imports are present before. Otherwise the adding of the elements will fail.
