      Package Specification

      + +

      This package provides a set of classes and interfaces that implement a debug + model based on JPDA/JDI (Java Debug Interface). It provides a set of interfaces + that extend the base set of debug element interfaces to provide access to Java + specific attributes and behavior. This model defines and provides utilities + for creating line breakpoints, method entry breakpoints, exception breakpoints, + and field watchpoints.
