Method Detail

getNeighborState

public java.util.Map<DeviceUID,java.util.Map<CodePath,java.lang.Object>> getNeighborState()

Description copied from interface: NetworkManager

Called by ProtelisVM during execution to collect the most recent information available from neighbors. The call is serial within the execution, so this should probably poll state maintained by a separate thread, rather than gathering state during this call.

Specified by:

getNeighborState in interface NetworkManager

Returns:

A map associating each neighbor with its shared state. The object returned should not be modified, and ProtelisVM will not change it either.

shareState

public void shareState(java.util.Map<CodePath,java.lang.Object> toSend)

Description copied from interface: NetworkManager

Called by ProtelisVM during execution to send its current shared state to neighbors. The call is serial within the execution, so this should probably queue up a message to be sent, rather than actually carrying out a lengthy operations during this call.

Specified by:

shareState in interface NetworkManager

Parameters:

toSend - Shared state to be transmitted to neighbors.
