private CompletableFuture<EvalNode> processRegExp(ExpAstNode node) {
    return CompletableFuture.supplyAsync(() -> {
        final LongAstNode flagsNumNode = node.getNode(1);
        final long flagsNum = flagsNumNode.getValue();

        int flags = 0;
        if ((flagsNum & AstRegexType.RE_IGNORECASE.getId()) != 0) {
            flags |= Pattern.CASE_INSENSITIVE;
        }/*from   ww w. j a va 2s  .  c  o m*/
        if ((flagsNum & AstRegexType.RE_MULTILINE.getId()) != 0) {

        }

        final boolean isGlobal = (flagsNum & AstRegexType.RE_GLOBAL.getId()) != 0;
