Example 1 with DenyAllAccessControl

use of com.facebook.presto.security.DenyAllAccessControl in project presto by prestodb.

the class ExpressionAnalyzer method analyzeExpressions.

private static ExpressionAnalysis analyzeExpressions(Session session, Metadata metadata, SqlParser sqlParser, RelationType tupleDescriptor, Map<Symbol, Type> types, Iterable<? extends Expression> expressions, List<Expression> parameters, boolean isDescribe) {
    // expressions at this point can not have sub queries so deny all access checks
    // in the future, we will need a full access controller here to verify access to functions
    Analysis analysis = new Analysis(null, parameters, isDescribe);
    ExpressionAnalyzer analyzer = create(analysis, session, metadata, sqlParser, new DenyAllAccessControl(), types);
    for (Expression expression : expressions) {
        analyzer.analyze(expression, Scope.builder().withRelationType(tupleDescriptor).build());
    }
    return new ExpressionAnalysis(analyzer.getExpressionTypes(), analyzer.getExpressionCoercions(), analyzer.getSubqueryInPredicates(), analyzer.getScalarSubqueries(), analyzer.getExistsSubqueries(), analyzer.getColumnReferences(), analyzer.getTypeOnlyCoercions(), analyzer.getQuantifiedComparisons(), analyzer.getLambdaArgumentReferences());
