template<typename T >

void tpie::bits::serialization_reader_base::unserialize ( T &  v )

inlineinherited

Unserialize an unserializable item from the stream.

An item of the given type must exist at the current point in the stream.

The code stream.unserialize(v) just calls unserialize(stream, v) via ADL.

template<typename IT >

void tpie::bits::serialization_reader_base::unserialize ( IT  a, IT  b  )

inlineinherited

Unserialize a sequence of unserializable items from the stream.

A sequence of the given item type must exist at the current point in the stream.

The code stream.unserialize(a, b) just calls unserialize(stream, a, b) via ADL.
