Detailed Description

NDNLPv2 fragmenter.

Constructor & Destructor Documentation

Reassembler()

ndnph::lp::Reassembler::Reassembler ( Region &  region )

inlineexplicit

Constructor.

Parameters

region

where to allocate memory for fragment payloads. This region may be shared with others fragmenters and reassemblers.

Member Function Documentation

add()

bool ndnph::lp::Reassembler::add ( const Fragment &  frag )

inline

Add a fragment.

If FragIndex is 0:

• Discard the existing reassembly buffer.
• Start a new reassembly buffer in the region passed to the constructor.
• Return true.

If frag comes after the previous fragment:

• Append to the existing reassembly buffer.
• Return true.

Otherwise:

• Return false.

discard()

void ndnph::lp::Reassembler::discard ( )

inline

Discard the reassembly buffer.

When the region is reset elsewhere (e.g. in another fragmenter or reassembler sharing the region), this function should be invoked to discard the reassembly buffer. Otherwise, undefined behavior may occur.

reassemble()

PacketClassify ndnph::lp::Reassembler::reassemble ( ) const

inline

Reassemble the packet if it's complete.

If the reassembly buffer contains a complete packet, return the reassembled packet. Otherwise, return a PacketClassify with Type::None .
