java.lang.Object

org.eclipse.rdf4j.rio.hdt.HDTPart

org.eclipse.rdf4j.rio.hdt.HDTTriples

class HDTTriples
extends HDTPart

HDT Triples Part.

This part starts with $HDT, followed by a byte indicating the type of the part, the NULL-terminated URI string for the format, and optionally one or more key=value; properties.

These properties may include the order (SPO, SOP...), and the number of triples.

Then a NULL byte, followed by the 16-bit CRC ($HDT and NULL included)

Structure:

+------+------+-----+------+------------+------+-------+
| $HDT | type | URI | NULL | key=value; | NULL | CRC16 |
+------+------+-----+------+------------+------+-------+
