public class ClassMap extends HashMap<String,String>
A hash table associating class names with different names.This hashtable is used for replacing class names in a class definition or a method body. Define a subclass of this class if a more complex mapping algorithm is needed. For example,
class MyClassMap extends ClassMap { public Object get(Object jvmClassName) { String name = toJavaName((String)jvmClassName); if (name.startsWith("java.")) return toJvmName("java2." + name.substring(5)); else return super.get(jvmClassName); } }This subclass maps
java.lang.Stringtojava2.lang.String. Note thatget()receives and returns the internal representation of a class name. For example, the internal representation ofjava.lang.Stringisjava/lang/String.Note that this is a map from
StringtoString.

Method Detail
-
put
public void put(CtClass oldname, CtClass newname)
Maps a class name to another name in this hashtable. The names are obtained with callingClass.getName(). This method translates the given class names into the internal form used in the JVM before putting it in the hashtable.- Parameters:
oldname- the original class namenewname- the substituted class name.
-
put
public String put(String oldname, String newname)
Maps a class name to another name in this hashtable. If the hashtable contains another mapping from the same class name, the old mapping is replaced. This method translates the given class names into the internal form used in the JVM before putting it in the hashtable.If
oldnameis identical tonewname, then this method does not perform anything; it does not record the mapping fromoldnametonewname. Seefixmethod.
-
putIfNone
public void putIfNone(String oldname, String newname)
Is equivalent toput()except that the given mapping is not recorded into the hashtable if another mapping fromoldnameis already included.- Parameters:
oldname- the original class name.newname- the substituted class name.
-
get
public String get(Object jvmClassName)
Returns the class name to wihch the givenjvmClassNameis mapped. A subclass of this class should override this method.This method receives and returns the internal representation of class name used in the JVM.

-
fix
public void fix(CtClass clazz)
Prevents a mapping from the specified class name to another name.
-
fix
public void fix(String name)
Prevents a mapping from the specified class name to another name.
-
