"Smart pointer" base class; do not use directly: use LocalPointer etc.
Base class for 'pure' C++ implementations of uenum api.

virtual const char * next(int32_t *resultLength, UErrorCode &status)
virtual const UnicodeString * snext(UErrorCode &status)
UnicodeString * setChars(const char *s, int32_t length, UErrorCode &status)
Converts s to Unicode and sets unistr to the result.

int32_t charsCapacity
Capacity of chars, for use with default implementations and subclasses.

char * chars
char * buffer for use with default implementations and subclasses.

StringEnumeration()
Default constructor for use with default implementations and subclasses.
void ensureCharsCapacity(int32_t capacity, UErrorCode &status)
Ensures that chars is at least as large as the requested capacity.
UnicodeString unistr
UnicodeString field for use with default implementations and subclasses.

virtual int32_t count(UErrorCode &status) const =0
virtual UBool operator==(const StringEnumeration &that) const
Compares this enumeration to other to check if both are equal.
virtual ~StringEnumeration()
Destructor.
virtual StringEnumeration * clone() const
Clone this object, an instance of a subclass of StringEnumeration.
virtual UBool operator!=(const StringEnumeration &that) const
Compares this enumeration to other to check if both are not equal.
