Member Function Documentation

◆ resolve_duplicate_metadata()

string MyCompactor::resolve_duplicate_metadata	(	const string &	key,
		size_t	num_tags,
		const string	tags[]
	)

virtual

Resolve multiple user metadata entries with the same key.

When merging, if the same user metadata key is set in more than one input, then this method is called to allow this to be resolving in an appropriate way.

The default implementation just returns tags[0].

For multipass this will currently get called multiple times for the same key if there are duplicates to resolve in each pass, but this may change in the future.

Since 1.4.6, an implementation of this method can return an empty string to indicate that the appropriate result is to not set a value for this user metadata key in the output database. In older versions, you should not return an empty string.

Parameters

key	The metadata key with duplicate entries.
num_tags	How many tags there are.
tags	An array of num_tags strings containing the tags to merge.

Reimplemented from Xapian::Compactor.

◆ set_status()

void MyCompactor::set_status	(	const string &	table,
		const string &	status
	)

virtual

Update progress.

Subclass this method if you want to get progress updates during compaction. This is called for each table first with empty status, And then one or more times with non-empty status.

The default implementation does nothing.

Parameters

table	The table currently being compacted.
status	A status message.
