ZBarSymbolSet Class Reference
=============================
.. class:: ZBarSymbolSet
:Inherits from: :class:`NSObject`
:Conforms to: :class:`NSFastEnumeration`
A symbol set is a simple container for the symbols scanned from an image.
It supports :class:`NSFastEnumeration`, and not much else... Use it to
iterate through the :class:`ZBarSymbol` objects in a decode result set::
ZBarSymbolSet *symbols = image.symbols;
for(ZBarSymbol *symbol in symbols) {
// process result
}
This class is a simple wrapper around a :type:`zbar_symbol_set_t` C object
(q.v.)
Properties
----------
.. member:: int count
The number of symbols in the set. (read-only)
.. member:: const zbar_symbol_set_t *zbarSymbolSet
Retrieve the underlying C object instance. (read-only)
Instance Methods
----------------
.. _`initWithSymbolSet:`:
.. describe:: - (id) initWithSymbolSet:(const zbar_symbol_set_t*)set
Initialize a symbol set wrapper, given the C object to wrap.
:set: The C object to wrap.
:Returns: The initialized symbol set, or nil if an error occurred.
