const TMapIter &

aIter

)

const

This operator compares two TMapIter objects.

operator*()

TObject * TMapIter::operator* ( ) const

virtual

Return pointer to current object (a TPair) or nullptr.

Reimplemented from TIterator.

Definition at line 582 of file TMap.cxx.

operator=() [1/2]

TIterator & TMapIter::operator= ( const TIterator &  rhs )
