Parameters:

id - the object id that was inserted

insertAll

public void insertAll(DBIDs ids)

Inserts the specified objects into this index. If a bulk load mode is implemented, the objects are inserted in one bulk.

Specified by:

insertAll in interface Index

Parameters:

ids - the objects to be inserted

delete

public boolean delete(DBID id)

Deletes the specified object from this index.

Specified by:

delete in interface Index

Parameters:

id - Object to remove

Returns:

true if this index did contain the object with the specified id, false otherwise

Description copied from interface: Index

Deletes the specified objects from this index.

Specified by:

deleteAll in interface Index

Parameters:

ids - Objects to remove
