Member Function Documentation

subAccount()

virtual void xrpl::InfoSub::Source::subAccount ( ref ispListener, hash_set< AccountID > const & vnaAccountIDs, bool realTime )

pure virtual

Implemented in xrpl::NetworkOPsImp.

unsubAccount()

virtual void xrpl::InfoSub::Source::unsubAccount ( ref isplistener, hash_set< AccountID > const & vnaAccountIDs, bool realTime )

pure virtual

Implemented in xrpl::NetworkOPsImp.

unsubAccountInternal()

virtual void xrpl::InfoSub::Source::unsubAccountInternal ( std::uint64_t uListener, hash_set< AccountID > const & vnaAccountIDs, bool realTime )

pure virtual

Implemented in xrpl::NetworkOPsImp.

subAccountHistory()

virtual ErrorCodeI xrpl::InfoSub::Source::subAccountHistory ( ref ispListener, AccountID const & account )

pure virtual

subscribe an account's new transactions and retrieve the account's historical transactions

Returns

rpcSUCCESS if successful, otherwise an error code

Implemented in xrpl::NetworkOPsImp.

unsubAccountHistory()

virtual void xrpl::InfoSub::Source::unsubAccountHistory ( ref ispListener, AccountID const & account, bool historyOnly )

pure virtual

unsubscribe an account's transactions

Parameters

historyOnly

if true, only stop historical transactions

Note

once a client receives enough historical transactions, it should unsubscribe with historyOnly == true to stop receiving more historical transactions. It will continue to receive new transactions.

Implemented in xrpl::NetworkOPsImp.

unsubAccountHistoryInternal()

virtual void xrpl::InfoSub::Source::unsubAccountHistoryInternal ( std::uint64_t uListener, AccountID const & account, bool historyOnly )

pure virtual

Implemented in xrpl::NetworkOPsImp.

pubManifest()

virtual void xrpl::InfoSub::Source::pubManifest ( Manifest const & )

pure virtual

Implemented in xrpl::NetworkOPsImp.

subServer()

virtual bool xrpl::InfoSub::Source::subServer ( ref ispListener, json::Value & jvResult, bool admin )

pure virtual

unsubServer()

virtual bool xrpl::InfoSub::Source::unsubServer ( std::uint64_t uListener )

pure virtual

Implemented in xrpl::NetworkOPsImp.

subBook()

virtual bool xrpl::InfoSub::Source::subBook ( ref ispListener, Book const &  )

pure virtual

Implemented in xrpl::NetworkOPsImp.

unsubBook()

virtual bool xrpl::InfoSub::Source::unsubBook ( ref ispListener, Book const &  )

pure virtual

Remove a book subscription for a live subscriber.

Clears the book from the subscriber's own tracking set (InfoSub::bookSubscriptions_) and then removes the server-side entry from subBook_. Call this from RPC unsubscribe handlers.

Parameters

ispListener	The subscriber requesting removal.
book	The order book to unsubscribe from.

Returns

true if the entry was present and removed, false if the subscriber was not subscribed to book.

Note

Thread-safety: acquires subLock_ internally.

Do NOT call from ~InfoSub(). Use unsubBookInternal instead to avoid a redundant write-back to bookSubscriptions_ on a partially-destroyed object.

Implemented in xrpl::NetworkOPsImp.

unsubBookInternal()

virtual bool xrpl::InfoSub::Source::unsubBookInternal ( std::uint64_t uListener, Book const &  )

pure virtual

Remove a book subscription during InfoSub teardown.

Removes only the server-side entry from subBook_. Does NOT touch InfoSub::bookSubscriptions_ because the InfoSub is being destroyed. Called by ~InfoSub() for each book in bookSubscriptions_.

Parameters

uListener	The sequence number of the subscriber being torn down.
book	The order book entry to remove.

Returns

true if the entry was present and removed, false otherwise (e.g., already removed by a concurrent RPC unsubscribe).

Note

Thread-safety: acquires subLock_ internally.

Implemented in xrpl::NetworkOPsImp.
