Method Detail

getId

public String getId()

Description copied from interface: LocalUniqueId

Gets a string identifier that is unique to a proposition for all propositions with its proposition id. This string must be the same every time the proposition is accessed from the data source backend.

Specified by:

getId in interface LocalUniqueId

Returns:

string representation of this unique identifier.

getNumericalId

public int getNumericalId()

Description copied from interface: LocalUniqueId

Gets a number that is to unique to the proposition for all propositions for a keyid with the same proposition id. This number must be the same every time the proposition is accessed from the data source backend. If no such number can be constructed from the data in the data source, then you may return the same number for every proposition, but keep in mind that some query results handlers rely on a number to distinguish instances of data with the same value recorded at the same time. Such query results handlers may treat propositions with the same proposition id and numerical local unique id as duplicates.

Specified by:

getNumericalId in interface LocalUniqueId

Returns:

a numerical value unique to propositions with this id.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

clone

public LocalUniqueId clone()

Description copied from interface: LocalUniqueId

Makes a shallow copy of this instance.

Specified by:

clone in interface LocalUniqueId

Overrides:

clone in class Object

Returns:

a LocalUniqueId that is equal to this instance.
