Method and system for dynamic configuration of interceptors in a client-server environment
A computer implemented method/system of creating and managing one or more interceptors. The method comprises the steps of intrinsically chaining the interceptors, and storing state information, in at least one of the chained interceptors, directed to a reference to the next interceptor. A server computer in a client-sever environment that includes a processor configured to generate one or more interceptors and to intrinsically chain the interceptors, and a memory associated with at least one of the chained interceptors and configured to store state information directed to a reference to the next interceptor thereof. The method/system, in various embodiments, includes dissimilar interceptors, callbacks, and flyweight pattern weighting.
1. A computer implemented method of creating and managing one or more interceptors, comprising:
intrinsically chaining, using a processor, said interceptors,
storing state information, using said processor, in at least one of the chained interceptors, directed to a reference to a next interceptor,
providing callbacks, using said processor, within said chained interceptors, and whereby a request only has to traverse said chained interceptors once while allowing said chained interceptors that need to intercept processing at additional points to do so by wrapping a callback interface, and
wherein server request callback implementations provided by Object Request Broker services delegate read inputs operations back to server request callback instances they wrap, unless they are causing an exception to be returned.
2. The method of claim 1 , wherein the server request callback implementations provided by he Object Request Broker services delegate write output operations back to the server request callback instances they wrap.
3. An article of manufacture comprising non-transitory computer readable storage medium having stored thereon computer readable program code implementing a method of creating and managing one or more interceptors, said medium comprising:
computer readable program code configured to intrinsically chain said interceptors,
computer readable program code configured to store state information, in at least one of the chained interceptors, directed to a reference to a next interceptor,
computer readable program code configured to provide callbacks within said chained interceptors, and
whereby a request only has to traverse said chained interceptors once while allowing said chained interceptors that need to intercept processing at additional points to do so by wrapping a callback interface, and
wherein server request callback implementations provided by Object Request Broker services delegate read inputs operations back to server request callback instances they wrap, unless they are causing an exception to be returned.
4. The article of manufacture of claim 3 , wherein the server request callback implementations provided by the Object Request Broker services delegate write output operations back to the server request callback instances they wrap.
