    for (StatementContext statement : ctx.statement()) {
        statements.add((AStatement) visit(statement));
    }
    return new SSource(scriptInterface, settings, sourceName, sourceText, debugStream, (MainMethodReserved) reserved.pop(), location(ctx), functions, globals, statements);
}

Example 2 with AStatement

use of org.elasticsearch.painless.node.AStatement in project elasticsearch by elastic.
