Member Function Documentation

bool DFPolicy::forward

(

DTN::Bundle *

b

)

[virtual]

Attepmt to forward a Bundle.

Concrete derived classes must implement this.

Parameters:

b

A Bundle to forward

Return values:

	true	b was forwarded
	false	b was not forwarded and should be considered for local storage

Implements DTN::ForwardingPolicy.

DTN::Bundle * DFPolicy::forwardOn

(

const DTN::Link &

l

)

[virtual]

Attepmt to forward along a Link that has become available.

Concrete derived classes must implement this.

Parameters:

l

A Link capable of transmitting a new Bundle

Returns:

a Bundle to forward

Implements DTN::ForwardingPolicy.
