Interface ProgramUnit
public interface ProgramUnit
An abstract program unit.
Any structural unit of a base program (class, member, ...). Units exclude the code.
When referencing a program unit, the client can retrieve unit
locators using getLocator()
or more specific methods. This
locators shall be used conjointly whith an Instrumentor
implementation in order to
perform aspetual transformations of the program (e.g. type merging,
parameters adding,...).
Program units also supports metadatas, i.e. the ability to add extra information on the base program so that the client can extends its meaning very easily.
