Features

  • Process Variables

    • The library provides a way to construct a generic adapter for every process variable.
    • The adapter contains variable type.
    • The adapter can be applied in any context (RuntimeService, TaskService, CaseService, DelegateExecution, DelegateTask, DelegateCaseExecution, VariableMap, LockedExternalTask).
    • The adapter offers methods to read, write, update and remove variable values.
    • The adapter works for all types supported by Camunda BPM. This includes primitive types, object and container types ( List<T>, Set<T>, Map<K , V> ).
    • The adapter supports global / local variables.
    • The adapter allows a default value or null in case a variable is not set.
    • The adapter support transient variables.
    • Fluent API helper are available in order to set, remove or update multiple variables in the same context (VariableMapBuilder, VariableReader and GlobalVariableWriter).

  • Process Variable Guards

    • Generic support for VariableGuard for evaluation of a list of VariableConditions
    • Condition to check if variable exists.
    • Condition to check if variable doesn't exist
    • Condition to check if variable has a predefined value.
    • Condition to check if variable has one of predefined values.
    • Condition to check if variable matches condition specified by a custom function.
    • Condition to check if variable matches provided regular expression.
    • Condition to check if variable is a valid email address.
    • Condition to check if variable is a valid UUID.
    • DefaultGuardTaskListener to construct variable conditions guards easily.
    • DefaultGuardExecutionListener to construct variable conditions guards easily.

  • Anti-Corruption-Layer

    • Generic support for AntiCorruptionLayer for protection and influence of variable modification in signalling and message correlation.
    • Helper methods for the client to wrap variables in a transient carrier.
    • Execution listener to handle VariableGuard-based conditions and VariableMapTransformer-based modifications.
    • Task listener to handle VariableGuard-based conditions and VariableMapTransformer-based modifications.
    • Factory methods to create AntiCorruptionLayer with a VariableGuard (see CamundaBpmDataACL)
    • Factory methods to create AntiCorruptionLayer without a VariableGuard (see CamundaBpmDataMapper)
