com.google.common.collect.UnmodifiableIterator<T>

com.google.common.collect.AbstractIterator<SparqlStmt>

org.aksw.jenax.stmt.util.SparqlStmtIterator

All Implemented Interfaces:

Iterator<SparqlStmt>

public class SparqlStmtIterator
extends com.google.common.collect.AbstractIterator<SparqlStmt>

An iterator over a string that holds a sequence of SPARQL queries; uses positions reported by parse exceptions to find the boundaries of queries. The provided parser must operate in classifier mode - i.e. it must not throw QueryParseExceptions but report them via SparqlStmt.getParseException(). TODO Ideally, an extension to the jena sparql grammar should allow parsing such sequences of queries.
