Method Detail

getPrettyPrintableName

public java.lang.String getPrettyPrintableName()

Description copied from interface: IInputKey

A user-friendly name that can be shown on screen for degug purposes, included in exceptions, etc.

getStringID

public java.lang.String getStringID()

Description copied from interface: IInputKey

An internal string identifier that can be used to uniquely identify to input key (relevant for distributed applications).

getArity

public int getArity()

Description copied from interface: IInputKey

The width of tuples in this relation.

isEnumerable

public boolean isEnumerable()

Description copied from interface: IInputKey

Returns true iff instance tuples of the key can be enumerated.

If false, the runtime can only test tuple membership in the extensional relation identified by the key, but not enumerate member tuples in general.
