Detailed Description

The basic transaction that is broadcasted on the network and contained in blocks.

A transaction can contain multiple inputs and outputs.

Constructor & Destructor Documentation

◆ CTransaction() [1/4]

CTransaction::CTransaction ( const CMutableTransaction tx)
explicit

Convert a CMutableTransaction into a CTransaction.

Definition at line 95 of file transaction.cpp.

◆ CTransaction() [2/4]

CTransaction::CTransaction ( CMutableTransaction &&  tx)
explicit

Definition at line 96 of file transaction.cpp.

◆ CTransaction() [3/4]

template<typename Stream >
CTransaction::CTransaction ( deserialize_type  ,
const TransactionSerParams params,
Stream &  s 
)
inline

This deserializing constructor is provided instead of an Unserialize method.

Unserialize is not possible, since it would require overwriting const fields.

Definition at line 335 of file transaction.h.

◆ CTransaction() [4/4]

template<typename Stream >
CTransaction::CTransaction ( deserialize_type  ,
ParamsStream< TransactionSerParams, Stream > &  s 
)
inline

Definition at line 337 of file transaction.h.
