public interface ClassTargetSelector
This interface represents policies for selecting a class to allocate at a given new site. The most obvious such policy would be
to look at the relevant class hierarchy and lookup the appropriate class based on the type reference at the new site. However,
other policies are possible for purposes such as providing an abstraction of unanalyzed libraries or specialized J2EE
functionality.
Such policies are consulted by the different analysis mechanisms, both the flow-based and non-flow algorithms. The current
mechanism is that the policy object are registered with the AnalysisOptions object, and all analyses that need to analyze
allocations ask that object for the class selector to use.
In general, for specialized selectors, it is good practice to build selectors that handle the special case of interest, and
otherwise delegate to a child selector. When registering with the AnalysisOptions object, make the child selector be whatever the
options object had before.
