Extensions for working with blocks.

Constructor & Destructor Documentation

BlockExtensions() [1/2]

catapult::extensions::BlockExtensions::BlockExtensions ( const GenerationHash &  generationHash )

explicit

Creates extensions for blocks containing only basic transactions for the network with the specified generation hash (generationHash).

Here is the call graph for this function:

BlockExtensions() [2/2]

catapult::extensions::BlockExtensions::BlockExtensions	(	const GenerationHash &	generationHash,
		const model::TransactionRegistry &	transactionRegistry
	)

Creates extensions for blocks containing transactions registered in transactionRegistry for the network with the specified generation hash (generationHash).

Member Function Documentation

calculateBlockTransactionsHash()

void catapult::extensions::BlockExtensions::calculateBlockTransactionsHash	(	const model::Block &	block,
		Hash256 &	blockTransactionsHash
	)		const

Calculates the block transactions hash of block into blockTransactionsHash.

Note

This function requires a full block and will calculate all transaction hashes.
