Interface ClassResearcher

All Known Implementing Classes:
AndroidClassResearcher, DefaultClassResearcher

public interface ClassResearcher

The ClassResearcher is used to learn about a Java class mentioned in Jess source. By abstracting the notion of reflection into a separate class, we can use different reflection mechanisms in different situations. For example, in the JessDE, we can use Eclipse's own machinery instead of Java reflection, so that we can learn about classes without actually loading them.
