Class Utf8_Enumeration

java.lang.Object
  soot.coffi.Utf8_Enumeration

All Implemented Interfaces:

Enumeration

public class Utf8_Enumeration
extends Object
implements 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.

Field Summary

int	c The latest character, as determined by nextElement.

Constructor Summary

Utf8_Enumeration()
For creating an empty enumeration; you must use reset() after this to initialize the enumeration.

Utf8_Enumeration(byte[] b)
For creating a normal enumeration of the given Utf8 string.

Method Summary

boolean	hasMoreElements() true if the entire string hasn't been enumerated yet.
Object	nextElement() Determines the next Utf8 character, and stores it in c.
void	reset(byte[] b) Resets this object to be an enumeration of the given Utf8 string.
