parseDescriptor

public void parseDescriptor(String descriptor,
                            int modifiers)

This method parses a descriptor and adds the package of the descriptor to the referenced packages. The syntax of the descriptor is:

   descriptor ::= ( '(' reference * ')' )? reference
   reference  ::= 'L' classname ( '<' references '>' )? ';' | 'B' | 'Z' | ... | '+' | '-' | '['
 

This methods uses heavy recursion to parse the descriptor and a roving pointer to limit the creation of string objects.

Parameters:

descriptor - The to be parsed descriptor

rover - The pointer to start at

getReferred

public Set<Descriptors.PackageRef> getReferred()

getAbsolutePath

public String getAbsolutePath()

getSourceFile

public String getSourceFile()

reset

public void reset()

.class construct for different compilers sun 1.1 Detect static variable class$com$acme$MyClass 1.2 " 1.3 " 1.4 " 1.5 ldc_w (class) 1.6 " eclipse 1.1 class$0, ldc (string), invokestatic Class.forName 1.2 " 1.3 " 1.5 ldc (class) 1.6 " 1.5 and later is not an issue, sun pre 1.5 is easy to detect the static variable that decodes the class name. For eclipse, the class$0 gives away we have a reference encoded in a string. compilerversions/compilerversions.jar contains test versions of all versions/compilers.
