Default constructor

Member Function Documentation

◆ destroy()

void TSLVersionHistorySet::destroy ( )

Destroy method - used to delete the object.

◆ empty()

bool TSLVersionHistorySet::empty ( ) const

Returns true if the collection is empty, false otherwise.

◆ getCurrentArchiveVersion()

TSLHistoryVersion TSLVersionHistorySet::getCurrentArchiveVersion ( ) const

Returns the version number that is currently being archived.

◆ getHistory()

void TSLVersionHistorySet::getHistory	(	int	N,
		TSLHistoryVersion &	version,
		TSLHistoryTimestamp &	timestamp,
		const TSLVersionUserInfo *&	userInfo ) const

Returns information for the Nth history in the collection.

Parameters

N	The index required.
version	The version number of the Nth history.
timestamp	The timestamp of the Nth history.
userInfo	A list of the user versions and their change extents for the Nth history. Note that the user should not attempt to modify the contents of this list.

◆ getNearestArchiveVersion()

TSLHistoryVersion TSLVersionHistorySet::getNearestArchiveVersion ( TSLHistoryTimestamp timestamp ) const

Returns the version number of the history that most closely matches the given timestamp.

Parameters

timestamp The timestamp.

Returns: Version that is closest to the timestamp or return 0.

◆ operator new() [1/2]

void * TSLVersionHistorySet::operator new ( size_t size )

Overridden allocation to redirect to MapLink.

◆ operator new() [2/2]

void * TSLVersionHistorySet::operator new	(	size_t	size,
		char *	filename,
		int	line )

When included in an MFC application in debug mode, the debug new expects this to be here. Override it and return the same as the normal one. The library must include it when compiled in release mode, since the user's application may be in debug mode.

◆ size()

int TSLVersionHistorySet::size ( ) const

Returns the size of the collection.
