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

(

)

Construct a CTransaction that qualifies as IsNull()

Definition at line 95 of file transaction.cpp.

CTransaction() [2/4]

CTransaction::CTransaction

(

const CMutableTransaction &

tx

)

Convert a CMutableTransaction into a CTransaction.

Definition at line 96 of file transaction.cpp.

CTransaction() [3/4]

CTransaction::CTransaction

(

CMutableTransaction &&

tx

)

Definition at line 97 of file transaction.cpp.

CTransaction() [4/4]

template<typename Stream >

CTransaction::CTransaction ( deserialize_type  , Stream &  s  )

inline

This deserializing constructor is provided instead of an Unserialize method.

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