# ConditionalOnPod constructor

const ConditionalOnPod({

1. List<ClassType<Object>> types = const [],
2. List<String> names = const [],

})

The `ConditionalOnPod` annotation in Jetleaf allows developers to conditionally process classes or methods based on the presence of specific pods in the application context.

This is especially useful when you want a configuration, service, or pod to only be loaded if another pod (or set of pods) already exists. Conditions can be defined by pod type, annotation, or name.

### Key Features:

- Require specific pod types to exist in the context.
- Require pods annotated with certain annotations.
- Require pods with given names.

### Usage Examples:

    // Require a specific pod type
    @ConditionalOnPod(types: [ClassType<DataSource>()])
    class JdbcTemplateConfig {}

    // Require a pod with a specific name
    @ConditionalOnPod(names: ['myCustomService'])
    class FallbackServiceConfig {}

Using this annotation ensures your configuration or pods are only registered when the expected pods are already available in the Jetleaf context.

## Implementation

    const ConditionalOnPod({this.types = const [], this.names = const []});
