delete

Member Function Documentation

virtual bool FIX8::Persister::del ( const f8String & key )

inlinevirtual

Delete a generic persisted value by specified key. Depending on specialisation, provide direct access to the persister implementation

Parameters

key	key to delete

Returns: true on success

Definition at line 109 of file persist.hpp.

109 { return false; }

virtual unsigned FIX8::Persister::find_nearest_highest_seqnum	(	const unsigned	requested,
		const unsigned	last
	)		const

pure virtual

Find the nearest highest sequence number from the sequence to last provided.

Parameters

requested	sequence number to start
last	highest sequence

Returns: the nearest sequence number or 0 if not found

Implemented in FIX8::FilePersister, and FIX8::MemoryPersister.

virtual bool FIX8::Persister::get	(	const unsigned	seqnum,

		unsigned &	target_seqnum
	)		const

pure virtual

Retrieve a sequence control record.

Parameters

sender_seqnum	sequence number of last sent message
target_seqnum	sequence number of last received message

Returns: true on success

Implemented in FIX8::FilePersister, and FIX8::MemoryPersister.

virtual unsigned FIX8::Persister::get_last_seqnum ( unsigned & to ) const

pure virtual

Retrieve sequence number of last peristed message.

Parameters
