Default constructor

CoalitionImpl

public CoalitionImpl(NodeStructure ns,
                     AttentionCodelet c)

Constructs a CoalitionImpl with specified content that is being created by specified AttentionCodelet

Parameters:

Specified by:

getContent in interface Coalition

Returns:

The BroadcastContent of the coalition

getCreatingAttentionCodelet

public AttentionCodelet getCreatingAttentionCodelet()

Description copied from interface: Coalition

Returns the creating AttentionCodelet that created this coalition

Specified by:

getId

public int getId()

Description copied from interface: Coalition

Returns the id

Specified by:

getId in interface Coalition

Returns:

the unique id of the Coalition
