equals

public boolean equals(Object o)

Description copied from interface: DBIDRef

WARNING: calling equality on a reference may be an indicator of incorrect usage, as it is not clear whether the programmer meant the references to be the same or the DBIDs. Use DBIDUtil.equal(de.lmu.ifi.dbs.elki.database.ids.DBIDRef, de.lmu.ifi.dbs.elki.database.ids.DBIDRef) or DBIDUtil.compare(de.lmu.ifi.dbs.elki.database.ids.DBIDRef, de.lmu.ifi.dbs.elki.database.ids.DBIDRef)!

Specified by:

equals in interface DBIDRef

Overrides:

equals in class Object

Parameters:

o - Object to compare with

Returns:

True when they are the same object

hashCode

public int hashCode()

Description copied from interface: DBIDRef

WARNING: Hash codes of this interface might not be stable (e.g. for iterators). Use DBIDUtil.deref(de.lmu.ifi.dbs.elki.database.ids.DBIDRef) to get an object with a stable hash code!

Specified by:

hashCode in interface DBIDRef

Overrides:

hashCode in class Object
