Detailed Description

Represents a set of transactions in RCLConsensus.

RCLTxSet is a thin wrapper over a SHAMap that stores the set of transactions.

Member Typedef Documentation

ID

using ripple::RCLTxSet::ID = uint256

Unique identifier/hash of the set of transactions.

Definition at line 69 of file RCLCxTx.h.

Tx

using ripple::RCLTxSet::Tx = RCLCxTx

The type that corresponds to a single transaction.

Definition at line 71 of file RCLCxTx.h.

Constructor & Destructor Documentation

RCLTxSet() [1/2]

ripple::RCLTxSet::RCLTxSet

(

std::shared_ptr< SHAMap >

m

)

Constructor.

Parameters

m	SHAMap to wrap

Definition at line 112 of file RCLCxTx.h.

RCLTxSet() [2/2]

ripple::RCLTxSet::RCLTxSet

(

MutableTxSet const &

m

)

Constructor from a previously created MutableTxSet.

Parameters

m	MutableTxSet that will become fixed

Definition at line 121 of file RCLCxTx.h.

Member Function Documentation

exists()

bool ripple::RCLTxSet::exists

(

Tx::ID const &

entry

)

const

Test if a transaction is in the set.

Parameters

entry

The ID of transaction to test.

Returns

Whether the transaction is in the set.

Definition at line 131 of file RCLCxTx.h.

find()

boost::intrusive_ptr<SHAMapItem const> const& ripple::RCLTxSet::find

(

Tx::ID const &

entry

)

const

Lookup a transaction.

Parameters

entry

The ID of the transaction to find.

Returns

A shared pointer to the SHAMapItem.

Note

Since find may not succeed, this returns a std::shared_ptr<const SHAMapItem> rather than a Tx, which cannot refer to a missing transaction. The generic consensus code uses the shared_ptr semantics to know whether the find was successful and properly creates a Tx as needed.

Definition at line 148 of file RCLCxTx.h.

id()

ID ripple::RCLTxSet::id

(

)

const

The unique ID/hash of the transaction set.

Definition at line 155 of file RCLCxTx.h.

compare()

std::map<Tx::ID, bool> ripple::RCLTxSet::compare

(

RCLTxSet const &

j

)

const

Find transactions not in common between this and another transaction set.

Parameters

j	The set to compare with

Returns

Map of transactions in this set and j but not both. The key is the transaction ID and the value is a bool of the transaction exists in this set.

Definition at line 169 of file RCLCxTx.h.
