Detailed Description

This represents a signed transaction that will never have its operations, signatures etc. modified again, after initial creation. It is therefore safe to cache results from various calls.

Member Function Documentation

get_packed_size()

uint64_t graphene::protocol::precomputable_transaction::get_packed_size ( ) const

overridevirtual

Reimplemented from graphene::protocol::transaction.

Definition at line 448 of file transaction.cpp.

get_signature_keys()

const flat_set< public_key_type > & graphene::protocol::precomputable_transaction::get_signature_keys ( const chain_id_type &  chain_id ) const

overridevirtual

Extract public keys from signatures with given chain ID.

Parameters

chain_id

A chain ID

Returns

Public keys

Note

If _signees is empty, E.G. when it's the first time calling this function for the signed transaction, public keys will be extracted with given chain ID, and be stored into the mutable _signees field, then _signees will be returned; otherwise, the chain_id parameter will be ignored, and _signees will be returned directly.
