Class ExtentValue

java.lang.Object

com.tectonica.jonix.onix3.ExtentValue

All Implemented Interfaces:

OnixElement<Double>, OnixTag, Serializable

public class ExtentValue
extends Object
implements OnixElement<Double>, Serializable

Extent value

The numeric value of the extent specified in <ExtentType>. Optional, and non-repeating. However, either <ExtentValue> or <ExtentValueRoman>, or both, must be present in each occurrence of the <Extent> composite; and it is very strongly recommended that <ExtentValue> should always be included, even when the original product uses Roman numerals.

Format	Positive real number, with explicit decimal point when required, as appropriate for the units specified in <ExtentUnit>. Suggested maximum length 8 characters
Reference name	<ExtentValue>
Short tag	<b219>
Cardinality	0…1
Example	<b219>2.5</b219>

This tag may be included in the following composites:

• <Extent>

Possible placements within ONIX message:

• Product ⯈ DescriptiveDetail ⯈ Extent ⯈ ExtentValue
