Method HasBlockAndState

core/blockchain.go:701–708

HasBlockAndState checks if a block and associated state trie is fully present in the database or not, caching it if present.

(hash common.Hash, number uint64)

// HasBlockAndState checks if a block and associated state trie is fully present
// in the database or not, caching it if present.
func (bc *BlockChain) HasBlockAndState(hash common.Hash, number uint64) bool {
	// Check first that the block itself is known
	block := bc.GetBlock(hash, number)
	if block == nil {
		return false
	}
	return bc.HasState(block.StateRoot())
}

// GetBlock retrieves a block from the database by hash and number,
// caching it if found.
