Lucy::Index::Snapshot - Point-in-time index file list.
my $snapshot = Lucy::Index::Snapshot->new; $snapshot->read_file( folder => $folder ); # load most recent snapshot my $files = $snapshot->list; print "$_\n" for @$files;
A Snapshot is list of index files and folders. Because index files, once written, are never modified, a Snapshot defines a point-in-time view of the data in an index.
IndexReader objects interpret the data associated with a single Snapshot.
my $snapshot = Lucy::Index::Snapshot->new;
Constructor. Takes no arguments.
Return an array of all entries.
Return the number of entries (including directories).
Add a filepath to the snapshot.
Delete a filepath from the snapshot.
Returns: true if the entry existed and was successfully deleted, false otherwise.
Decode a snapshot file and initialize the object to reflect its contents.
Returns: the object, allowing an assignment idiom.
Write a snapshot file. The caller must lock the index while this operation takes place, and the operation will fail if the snapshot file already exists.
Set the path to the file that the Snapshot object serves as a proxy for.
Get the path to the snapshot file. Initially undef; updated by read_file(), write_file(), and set_path().
Lucy::Index::Snapshot isa Lucy::Object::Obj.
