Class SPARQLJSONParserBase

java.lang.Object

org.openrdf.query.resultio.QueryResultParserBase

com.bigdata.rdf.rio.json.SPARQLJSONParserBase

All Implemented Interfaces:

org.openrdf.query.resultio.QueryResultParser

Direct Known Subclasses:

BigdataSPARQLResultsJSONParser

public abstract class SPARQLJSONParserBase
extends org.openrdf.query.resultio.QueryResultParserBase

Abstract base class for SPARQL Results JSON Parsers. Provides a common implementation of both boolean and tuple parsing.

Bigdata Changes:

• Changed the visibility of the method parseValue() from private to protected so we could override it.
• Pulled some code out of parseQueryResultInternal into its own method so that we can override it.
