Detailed Description

Micro version of cryptonode::core class Micro version of constructor, init and destructor are implemted.

Just enough to read the blockchain database for use in the example.

Constructor & Destructor Documentation

MicroCore()

etneg::MicroCore::MicroCore

(

)

The constructor is interesting, as m_mempool and m_blockchain_storage depend on each other.

So basically m_mempool is initialized with reference to Blockchain (i.e., Blockchain&) and m_blockchain_storage is initialized with reference to m_mempool (i.e., tx_memory_pool&)

The same is done in cryptonode::core.

~MicroCore()

etneg::MicroCore::~MicroCore ( )

virtual

De-initialized Blockchain.

since blockchain is opened as MDB_RDONLY need to manually free memory taken on heap by BlockchainLMDB

Member Function Documentation

find_output_in_tx()

bool etneg::MicroCore::find_output_in_tx	(	const transaction &	tx,
		const public_key &	output_pubkey,
		tx_out &	out,
		size_t &	output_index
	)

Find output with given public key in a given transaction

get_blk_timestamp()

uint64_t etneg::MicroCore::get_blk_timestamp

(

uint64_t

blk_height

)

get_blkchain_path()

string etneg::MicroCore::get_blkchain_path

(

)

get_block_by_height()

bool etneg::MicroCore::get_block_by_height	(	const uint64_t &	height,
		block &	blk
	)

Get block by its height

returns true if success

get_core()

Blockchain & etneg::MicroCore::get_core

(

)

Get m_blockchain_storage. Initialize m_blockchain_storage with the BlockchainLMDB object.

get_tx() [1/2]

bool etneg::MicroCore::get_tx	(	const crypto::hash &	tx_hash,
		transaction &	tx
	)

Get transaction tx from the blockchain using it hash

get_tx() [2/2]

bool etneg::MicroCore::get_tx	(	const string &	tx_hash,
		transaction &	tx
	)

get_tx_hash_from_output_pubkey()

bool etneg::MicroCore::get_tx_hash_from_output_pubkey	(	const public_key &	output_pubkey,
		const uint64_t &	block_height,
		crypto::hash &	tx_hash,
		cryptonote::transaction &	tx_found
	)

Returns tx hash in a given block which contains given output's public key

init()

bool etneg::MicroCore::init	(	const string &	_blockchain_path,
		bool	testnet = false
	)

Initialized the MicroCore object.

Create BlockchainLMDB on the heap. Open database files located in blockchain_path. Initialize m_blockchain_storage with the BlockchainLMDB object.
