public void init()
          throws java.lang.Exception

init - does nothing - we need to have setRuntimeLogger called before getting our introspector, as the default vel introspector depends upon it.

Specified by:

init in interface Uberspect

java.lang.Exception

setRuntimeLogger

public void setRuntimeLogger(RuntimeLogger runtimeLogger)

Sets the runtime logger - this must be called before anything else besides init() as to get the logger. Makes the pull model appealing...
