Method Detail

getCommonSuperClassback to summary
protected String getCommonSuperClass(String type1, String type2)

Overrides org.objectweb.asm.ClassWriter.getCommonSuperClass.

Doc from org.objectweb.asm.ClassWriter.getCommonSuperClass.

Returns the common super type of the two given types. The default implementation of this method loads the two given classes and uses the java.lang.Class methods to find the common super class. It can be overridden to compute this common super type in other ways, in particular without actually loading any class, or to take into account the class that is currently being generated by this ClassWriter, which can of course not be loaded since it is under construction.

Parameters
type1:String

the internal name of a class (see Type#getInternalName()).

type2:String

the internal name of another class (see Type#getInternalName()).

Returns:String

the internal name of the common super class of the two given classes (see Type#getInternalName()).
