Constructor Detail

ParsedGraphQuery

public ParsedGraphQuery()

Creates a new graph query. To complete this query, a tuple expression needs to be supplied to it using ParsedQuery.setTupleExpr(TupleExpr).

ParsedGraphQuery

public ParsedGraphQuery(Map<String,String> namespaces)

Creates a new graph query. To complete this query, a tuple expression needs to be supplied to it using ParsedQuery.setTupleExpr(TupleExpr).

Parameters:

namespaces - A mapping of namespace prefixes to namespace names representing the namespaces that are used in the query.

ParsedGraphQuery

public ParsedGraphQuery(TupleExpr tupleExpr)

Creates a new graph query for the supplied tuple expression.

Parameters:

tupleExpr - A tuple expression representing the query, formulated in Sail Query Model objects.
