Class | Rcov::CallSiteAnalyzer |
In: |
lib/rcov.rb
|
Parent: | DifferentialAnalyzer |
A CallSiteAnalyzer can be used to obtain information about:
example.rb:
class X def f1; f2 end def f2; 1 + 1 end def f3; f1 end end analyzer = Rcov::CallSiteAnalyzer.new x = X.new analyzer.run_hooked do x.f1 end # .... analyzer.run_hooked do x.f3 # the information generated in this run is aggregated # to the previously recorded one end analyzer.analyzed_classes # => ["X", ... ] analyzer.methods_for_class("X") # => ["f1", "f2", "f3"] analyzer.defsite("X#f1") # => DefSite object analyzer.callsites("X#f2") # => hash with CallSite => count # associations defsite = analyzer.defsite("X#f1") defsite.file # => "example.rb" defsite.line # => 2
You can have several CallSiteAnalyzer objects at a time, and it is possible to nest the run_hooked / install_hook/remove_hook blocks: each analyzer will manage its data separately. Note however that no special provision is taken to ignore code executed "inside" the CallSiteAnalyzer class.
defsite information is only available for methods that were called under the inspection of the CallSiteAnalyzer, i.o.w. you will only have defsite information for those methods for which callsite information is available.
Classes whose methods have been called. Returns an array of strings describing the classes (just klass.to_s for each of them). Singleton classes are rendered as:
#<Class:MyNamespace::MyClass>
Returns a hash with CallSite => call count associations or nil Can be called in two ways:
analyzer.callsites("Foo#f1") # instance method analyzer.callsites("Foo.g1") # singleton method of the class
or
analyzer.callsites("Foo", "f1") analyzer.callsites("#<class:Foo>", "g1")
Returns a DefSite object corresponding to the given method Can be called in two ways:
analyzer.defsite("Foo#f1") # instance method analyzer.defsite("Foo.g1") # singleton method of the class
or
analyzer.defsite("Foo", "f1") analyzer.defsite("#<class:Foo>", "g1")
Methods that were called for the given class. See analyzed_classes for the notation used for singleton classes. Returns an array of strings or nil
