“…Obviously, introspection and intercession are expensive tasks when carried out during program execution. Many attempts have been done to improve this situation, most of them are related to move reflection from run-time to compile-time [4,11] or load-time [5]. But, there are still many situations where the introspection and intercession must take place at run-time.…”

In the last few years the interest in reflection has grown and many modern programming languages/environments (e.g., Java and .NET) have provided the programmer with reflective mechanisms, i.e., with the ability of dynamically looking into (introspect) the structure of the code from the code itself. In spite of its evident usefulness, reflection has many detractors, who claim that it is too inefficient to be used with real profit. In this work, we have investigated about the performance issue in the context of the Java reflection library and presented a different approach to the introspection in Java that improves its performances. The basic idea of the proposed approach consists of moving most of the overhead due to the dynamic introspection from run-time to compiletime. The efficiency improvement has been proved by providing a new reflection library compliant -that is, it provides exactly the same services -, with the standard Java reflection library based on the proposed approach. This paper is focused on speeding up the reification and the invocation of methods, i.e., on the class SmartMethod that replaces the class Method of the standard reflection library.

“…C++ templates can potentially recurse endlessly, and only a limited recursion-depth prevents this [10]. In other technologies which use a Turingcomplete language for metaobject manipulation, like CLOS [19], OpenC++ [9] or Jasper [36,37], generators potentially do not terminate as well.…”

We describe a type system for a generative mechanism that generalizes the concept of generic types by combining it with a controlled form of reflection. This mechanism makes many code generation tasks possible for which generic types alone would be insufficient. The power of code generation features are carefully balanced with their safety, which enables us to perform static type checks on generator code. This leads to a generalized notion of type safety for generators.

“…The model makes few assumptions about relationships between base and meta-entities: in principles, each meta-object can be connected to many referents, and each referent can be linked to several meta-objects (one at a time) during its lifecycle. However most implementations, for reason of efficiency, restrict this freedom: in OpenC++ [5] and ABCL-R [6] a meta-object is linked to one referent only, and each referent can have only one meta-object during its lifecycle. As a consequence, reflection granularity is at object level.…”

Abstract-The paper presents a new reflective model, called Channel Reification, which can be used in distributed computations to overcome difficulties experienced by other models in the literature when monitoring communication among objects. The channel is an extension of the message reification model. A Channel is a communication manager incarning successive messages exchanges by two objects: its application range between those of message reification and those of meta-object model. After a brief review of existing reflective models and how reflections can be used in distributed systems, channel reification is presented and compared to the widely used meta-object model. Applications of channel reification to protocol implementation, and to fault tolerant object systems are shown. Future extensions to this model are also summarized.
