Class Utf8_Enumeration

java.lang.Object

soot.coffi.Utf8_Enumeration

All Implemented Interfaces:

java.util.Enumeration

public class Utf8_Enumeration
extends java.lang.Object
implements java.util.Enumeration

An enumeration of a Utf8 allows one to run through the characters in a unicode string; used primarily for comparing unicode strings. Note that unlike regular enumerations, and to be efficient (ie to avoid allocating an object in each call to nextElement), the return value is accessed by this object's 'c' field, and nextElement merely returns this.
