1.5 and later is not an issue, sun pre 1.5 is easy to detect the static
variable that decodes the class name. |

parseDescriptor
public void parseDescriptor(String descriptor)
- 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 descriptorrover
- The pointer to start at
getPackage
public static String getPackage(String clazz)
getReferred
public Set<String> getReferred()
getPath
public String getPath()
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.

versions/compilers.
