Reflective Hooks
Java runtime class manipulation
Reflection allows dynamic inspection and manipulation of classes and objects on runtime.
JAWCE makes use of reflection for all hooks by default if your logic is written in Java

Each defined hook class should have a constructor that takes a HookArgs object as a single parameter.
The business logic can be in any method defined in the Java class.
Consider the example below
Template
6005:
type: text
template: "com.example.ExampleReflectionHook:getOrderInfo"
message: "Provide reference for order: {{ type }}, {{ currency }} {{ amount }}"
routes:
"re:\\d+": 6006
Java Code
@Sl4j
public class ExampleReflectionHook {
private final HookArgs args;
public ExampleReflectionHook(HookArgs args) {
this.args = args;
}
public Object getOrderInfo() {
log.info("Received hook args: {}", this.args);
// populate dynamic variables
args.setTemplateDynamicBody(
new TemplateDynamicBody(
null,
null,
Map.of(
"type", "FC Chair",
"currency", "USD",
"amount", 3.50
)
));
return args;
}
}
