Member Function Documentation

virtual void UniConfGen::NullIter::rewind ( ) [inline, virtual]

Rewinds the iterator.

Must be called prior to the first invocation of next().

Implements UniConfGen::Iter.

Definition at line 362 of file uniconfgen.h.

virtual bool UniConfGen::NullIter::next ( ) [inline, virtual]

Seeks to the next element in the sequence.

Returns true if that element exists. Must be called prior to the first invocation of key().

Implements UniConfGen::Iter.

Definition at line 363 of file uniconfgen.h.

virtual UniConfKey UniConfGen::NullIter::key ( ) const [inline, virtual]

Returns the current key.

Implements UniConfGen::Iter.

Definition at line 364 of file uniconfgen.h.

References UniConfKey::EMPTY.

virtual WvString UniConfGen::NullIter::value ( ) const [inline, virtual]

Returns the value of the current key.

You could just do a get(), but maybe your generator has a more efficient way.

Implements UniConfGen::Iter.
