sysio::testing::tester_network Class Reference

The tester_network class provides a simplistic virtual P2P network connecting testing_blockchains together. More...

Public Member Functions
void	connect_blockchain (base_tester &new_blockchain)
	Add a new blockchain to the network.
void	disconnect_blockchain (base_tester &leaving_blockchain)
	Remove a blockchain from the network.
void	disconnect_all ()
	Disconnect all blockchains from the network.
void	propagate_block (const signed_block &block, const base_tester &skip_db)
	Send a block to all blockchains in this network.

Protected Attributes
std::map< base_tester *, scoped_connection >	blockchains

Detailed Description

A tester may be connected to zero or more tester_networks at any given time. When a new tester joins the network, it will be synced with all other blockchains already in the network (blocks known only to the new chain will be pushed to the prior network members and vice versa, ignoring blocks not on the main fork). After this, whenever any blockchain in the network gets a new block, that block will be pushed to all other blockchains in the network as well.
