Interface WorkflowInputValidator

public interface WorkflowInputValidator
Interface for implementing custom workflow input validators. WorkflowInputValidator provides the mechanism for validating input data before workflow transitions are executed, ensuring data integrity and business rule compliance.

Validators are executed before transitions to ensure that all required data is present, correctly formatted, and meets business requirements. They can validate attribute values, check business rules, verify external system states, and perform any other validation logic required by the workflow.

Custom validators are registered with the workflow engine through the ExtensionProvider and can be referenced in workflow definitions by type and value.
