Dependency injection container

SEP managing lifecycle and injecting properties to managed nodes

Introduction

The generated SEP acts as dependency injection container for managed nodes, this section discusses DI capabilities. A generated SEP provides the following dependency injection features:

• Managed node references

  • Instantiating managed nodes in topological order.

  • Assigning scalar references between managed nodes.

  • Assigning vector references between managed nodes.

  • Reflection based reference assignment.

  • All reference are set before SEP init method exits.

• Property Setting

  • Setting scalar properties on nodes.

  • Setting vector properties on nodes.

  • Reflection based property setting.

  • All values set before SEP constructor exits.

• Invoking lifecycle methods on managed nodes in a predictable order.

The managed node references is covered extensively in the event processing and graph building sections. This section deals with property setting and lifecycle methods.
