| 43 | \class QScriptValueIterator
|
|---|
| 44 |
|
|---|
| 45 | \brief The QScriptValueIterator class provides a Java-style iterator for QScriptValue.
|
|---|
| 46 |
|
|---|
| 47 | \ingroup script
|
|---|
| 48 |
|
|---|
| 49 |
|
|---|
| 50 | The QScriptValueIterator constructor takes a QScriptValue as
|
|---|
| 51 | argument. After construction, the iterator is located at the very
|
|---|
| 52 | beginning of the sequence of properties. Here's how to iterate over
|
|---|
| 53 | all the properties of a QScriptValue:
|
|---|
| 54 |
|
|---|
| 55 | \snippet doc/src/snippets/code/src_script_qscriptvalueiterator.cpp 0
|
|---|
| 56 |
|
|---|
| 57 | The next() advances the iterator. The name(), value() and flags()
|
|---|
| 58 | functions return the name, value and flags of the last item that was
|
|---|
| 59 | jumped over.
|
|---|
| 60 |
|
|---|
| 61 | If you want to remove properties as you iterate over the
|
|---|
| 62 | QScriptValue, use remove(). If you want to modify the value of a
|
|---|
| 63 | property, use setValue().
|
|---|
| 64 |
|
|---|
| 65 | Note that QScriptValueIterator only iterates over the QScriptValue's
|
|---|
| 66 | own properties; i.e. it does not follow the prototype chain. You can
|
|---|
| 67 | use a loop like this to follow the prototype chain:
|
|---|
| 68 |
|
|---|
| 69 | \snippet doc/src/snippets/code/src_script_qscriptvalueiterator.cpp 1
|
|---|
| 70 |
|
|---|
| 71 | Note that QScriptValueIterator will not automatically skip over
|
|---|
| 72 | properties that have the QScriptValue::SkipInEnumeration flag set;
|
|---|
| 73 | that flag only affects iteration in script code. If you want, you
|
|---|
| 74 | can skip over such properties with code like the following:
|
|---|
| 75 |
|
|---|
| 76 | \snippet doc/src/snippets/code/src_script_qscriptvalueiterator.cpp 2
|
|---|
| 77 |
|
|---|
| 78 | \sa QScriptValue::property()
|
|---|
| 79 | */
|
|---|
| 80 |
|
|---|
| 81 | class QScriptValueIteratorPrivate
|
|---|
| 82 | {
|
|---|
| 83 | public:
|
