Constructor & Destructor Documentation

MemoryPtCacheView()

catapult::cache::MemoryPtCacheView::MemoryPtCacheView ( uint64_t  maxResponseSize, const PtDataContainer &  transactionDataContainer, utils::SpinReaderWriterLock::ReaderLockGuard &&  readLock  )

explicit

Creates a view around around a maximum response size (maxResponseSize), a partial transaction data container (transactionDataContainer) with lock context readLock.

Member Function Documentation

find()

model::WeakCosignedTransactionInfo catapult::cache::MemoryPtCacheView::find

(

const Hash256 &

hash

)

const

Finds a partial transaction in the cache with associated hash or returns nullptr if no such transaction exists.

shortHashPairs()

ShortHashPairRange catapult::cache::MemoryPtCacheView::shortHashPairs

(

)

const

Gets a range of short hash pairs of all transactions in the cache. A short hash pair consists of the first 4 bytes of the transaction hash and the first 4 bytes of the cosignature hash.

Here is the call graph for this function:

size()

size_t catapult::cache::MemoryPtCacheView::size

(

)

const

Returns the number of partial transactions in the cache.

unknownTransactions()

MemoryPtCacheView::UnknownTransactionInfos catapult::cache::MemoryPtCacheView::unknownTransactions

(

const ShortHashPairMap &

knownShortHashPairs

)

const

Gets a vector of all unknown transaction infos in the cache that do not have a short hash pair in knownShortHashPairs.
