## Member Function Documentation

### QBitVal::QBitVal ( QBitArray * a, uint i )

Constructs a reference to element i in the QBitArray a. This is what QBitArray::operator[] constructs its return value with.

### QBitVal::operator int ()

Returns the value referenced by the QBitVal.

### QBitVal & QBitVal::operator= ( const QBitVal & v )

Sets the value referenced by the QBitVal to that referenced by QBitVal v.

### QBitVal & QBitVal::operator= ( bool v )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Sets the value referenced by the QBitVal to v.
