basis

public Chain basis()

Retrieves the basis element of an interval.

Specified by:

basis in class PersistenceBasisInterval

Returns:

The Chain object representing the stored basis element.

hashCode

public int hashCode()

Overrides Object hashcode.

Overrides:

hashCode in class java.lang.Object
