◆ start()

void xrpl::LedgerCleanerImp::start ( )

overridevirtual

Implements xrpl::LedgerCleaner.

Definition at line 91 of file app/ledger/detail/LedgerCleaner.cpp.

◆ stop()

void xrpl::LedgerCleanerImp::stop ( )

overridevirtual

Implements xrpl::LedgerCleaner.

Definition at line 97 of file app/ledger/detail/LedgerCleaner.cpp.

◆ onWrite()

void xrpl::LedgerCleanerImp::onWrite ( beast::PropertyStream::Map & )

overridevirtual

Subclass override.

The default version does nothing.

Reimplemented from beast::PropertyStream::Source.

Definition at line 115 of file app/ledger/detail/LedgerCleaner.cpp.

◆ clean()

void xrpl::LedgerCleanerImp::clean ( json::Value const & parameters )

overridevirtual

Start a long running task to clean the ledger.

The ledger is cleaned asynchronously, on an implementation defined thread. This function call does not block. The long running task will be stopped by a call to stop().

Thread safety: Safe to call from any thread at any time.

Parameters

parameters A Json object with configurable parameters.

Implements xrpl::LedgerCleaner.

Definition at line 142 of file app/ledger/detail/LedgerCleaner.cpp.

◆ run()

void xrpl::LedgerCleanerImp::run ( )

private

Definition at line 226 of file app/ledger/detail/LedgerCleaner.cpp.

◆ getLedgerHash()

LedgerHash xrpl::LedgerCleanerImp::getLedgerHash	(	std::shared_ptr< ReadView const > &	ledger,
		LedgerIndex	index )

private

Definition at line 247 of file app/ledger/detail/LedgerCleaner.cpp.

◆ doLedger()

bool xrpl::LedgerCleanerImp::doLedger	(	LedgerIndex const &	ledgerIndex,
		LedgerHash const &	ledgerHash,
		bool	doNodes,
		bool	doTxns )

private

Process a single ledger.

Parameters

ledgerIndex	The index of the ledger to process.
ledgerHash	The known correct hash of the ledger.
doNodes	Ensure all ledger nodes are in the node db.
doTxns	Reprocess (account) transactions to SQL databases.

Returns: true if the ledger was cleaned.

Definition at line 271 of file app/ledger/detail/LedgerCleaner.cpp.

◆ getHash()

LedgerHash xrpl::LedgerCleanerImp::getHash	(	LedgerIndex const &	ledgerIndex,
		std::shared_ptr< ReadView const > &	referenceLedger )

private

Returns the hash of the specified ledger.

Parameters

ledgerIndex	The index of the desired ledger.
referenceLedger	[out] An optional known good subsequent ledger.

Returns: The hash of the ledger. This will be all-bits-zero if not found.

Definition at line 329 of file app/ledger/detail/LedgerCleaner.cpp.

◆ doLedgerCleaner()

void xrpl::LedgerCleanerImp::doLedgerCleaner ( )

private

Run the ledger cleaner.

Definition at line 378 of file app/ledger/detail/LedgerCleaner.cpp.

◆ name()

std::string const & beast::PropertyStream::Source::name ( ) const

nodiscardinherited

Returns the name of this source.

Definition at line 168 of file beast_PropertyStream.cpp.

◆ add() [1/2]

void beast::PropertyStream::Source::add ( Source & source )

inherited

Add a child source.

Definition at line 174 of file beast_PropertyStream.cpp.

◆ add() [2/2]

template<class Derived>

Derived * beast::PropertyStream::Source::add ( Derived * child )

inherited

Add a child source by pointer.

The source pointer is returned so it can be used in ctor-initializers.

Definition at line 338 of file PropertyStream.h.

◆ remove()

void beast::PropertyStream::Source::remove ( Source & child )

inherited

Remove a child source from this Source.

Definition at line 185 of file beast_PropertyStream.cpp.

◆ removeAll()

void beast::PropertyStream::Source::removeAll ( )

inherited

Remove all child sources from this Source.

Definition at line 196 of file beast_PropertyStream.cpp.

◆ writeOne()

void beast::PropertyStream::Source::writeOne ( PropertyStream & stream )

inherited

Write only this Source to the stream.

Definition at line 209 of file beast_PropertyStream.cpp.

◆ write() [1/2]

void beast::PropertyStream::Source::write ( PropertyStream & stream )

inherited

write this source and all its children recursively to the stream.

Definition at line 216 of file beast_PropertyStream.cpp.

◆ write() [2/2]

void beast::PropertyStream::Source::write	(	PropertyStream &	stream,
		std::string const &	path )

inherited

Parse the path and write the corresponding Source and optional children.

If the source is found, it is written. If the wildcard character '*' exists as the last character in the path, then all the children are written recursively.

Definition at line 228 of file beast_PropertyStream.cpp.

◆ find()

std::pair< PropertyStream::Source *, bool > beast::PropertyStream::Source::find ( std::string path )

inherited

Parse the dot-delimited Source path and return the result.

The first value will be a pointer to the Source object corresponding to the given path. If no Source object exists, then the first value will be nullptr and the second value will be undefined. The second value is a boolean indicating whether or not the path string specifies the wildcard character '*' as the last character.

print statement examples "parent.child" prints child and all of its children "parent.child." start at the parent and print down to child "parent.grandchild" prints nothing- grandchild not direct descendent "parent.grandchild." starts at the parent and prints down to grandchild "parent.grandchild.*" starts at parent, print through grandchild children
