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().

AbstractIntListLabel

public AbstractIntListLabel(String key,
 int[] value)

Creates an int label with given key and value.

Parameters:

key - the (only) key of this label.

value - the value of this label.

Method Details

wellKnownAttributeKey

public String wellKnownAttributeKey()

Description copied from interface: Label
