Member Function Documentation

◆ GetCollection()

const TCollection * TMapIter::GetCollection ( ) const
inlinevirtual

Implements TIterator.

Definition at line 163 of file TMap.h.

◆ operator!=() [2/2]

Bool_t TMapIter::operator!= ( const TMapIter aIter) const

This operator compares two TMapIter objects.

Definition at line 575 of file TMap.cxx.

◆ operator*()

TObject * TMapIter::operator* ( ) const
virtual
