RTSC Components Key Characteristics ü dual-existence • meta-code: runs on rich client platforms • target-code: runs on resource limited HW ü meta-code manages component lifecycle • build of component (including target-side) • integration during application assembly • monitoring during test and after deployment Benefits ü standardizes design-time optimizations • transparently binds alternate implementation • objects can be created at design-time • no embedded runtime requirements ü enables unlimited tooling opportunities • meta-code can proxy for target-code • components differentiate in meta-domain Application RTSC Component C RTSC Component B target-code meta-code RTSC A A Component target-code meta-code (C) (Java.
