fun injectBefore(targetClassName: String, methodName: String, parameterTypeNames: List<String> = emptyList(), owner: String? = null, handler: (UnsafeInvocationContext) -> Unit): UnsafeHandle
Injects a callback before target method execution (string-based overload).
Return
injection handle, usable by rollbackUnsafe
Parameters
target
target class fully-qualified name
method
target method name
parameter
parameter type names, e.g. int, java.lang.String
owner
script owner (nullable, auto-resolved from script context if null)
handler
before callback
fun injectBefore(method: Method, owner: String? = null, handler: (UnsafeInvocationContext) -> Unit): UnsafeHandle
Injects a callback before target method execution (Method overload).
Prefer this overload when a reflected Method is already available, to avoid string-signature assembly errors.
