目前唯一的方法是按照以下方式进行类型转换：
```
OdArray::iterator nextAttribute = leftEntityAttributeFilter.begin();
```
```
for (; nextAttribute != leftEntityAttributeFilter.end(); ++nextAttribute)
```
```
{
```
```
OdDAI::AttributePtr pAttrib = *nextAttribute;
```
```
OdDAI::InverseAttributePtr pInverse = OdDAI::InverseAttribute::cast(pAttrib);
```
```
if (!pInverse.isNull())
```
```
{
```
```
odPrintConsoleString(L"\nInverse attribute `%s` (%lu)", pInverse->name().c_str(), (OdUInt64)leftIterator->id().getHandle());
```
```
}
```
```
}
```
