Class AbstractIntListLabel

java.lang.Object

it.unimi.dsi.big.webgraph.labelling.AbstractLabel

it.unimi.dsi.big.webgraph.labelling.AbstractIntListLabel

All Implemented Interfaces:

Label, it.unimi.dsi.lang.FlyweightPrototype<Label>

Direct Known Subclasses:

FixedWidthIntListLabel

public abstract class AbstractIntListLabel
extends AbstractLabel
implements Label

An abstract (single-attribute) list-of-integers label.

This class provides basic methods for a label holding a list of integers. Concrete implementations may impose further requirements on the integer.

Implementing subclasses must provide constructors, Label.copy(), Label.fromBitStream(it.unimi.dsi.io.InputBitStream, long), Label.toBitStream(it.unimi.dsi.io.OutputBitStream, long) and possibly override toString().
