Class SparqlQueryParser

java.lang.Object

cz.cvut.kbss.jopa.query.sparql.SparqlQueryParser

All Implemented Interfaces:

QueryParser

public class SparqlQueryParser
extends Object
implements QueryParser

A simplified SPARQL query parser.

This implementation does not use any AST tree-based query string parsing as its only purpose is to split the query into chunks delimited by variable occurrences, so that the variables can be bound using parameters in the query API.

More diligent query parsing is left to the engine used to execute the resulting query.
