Example 5 with BraceExprToken

use of org.develnext.jphp.core.tokenizer.token.expr.BraceExprToken in project jphp by jphp-compiler.

the class ASMExpression method processOperator.

protected void processOperator(Stack<Token> stack, List<Token> result, OperatorExprToken current) {
    List<Token> list = new ArrayList<Token>();
    boolean isRightOperator = current != null && current.isRightSide();
    int prior = current == null ? -1 : current.getPriority();
    while (!stack.empty()) {
        Token el = stack.peek();
        int elPrior = getPriority(el);
        if (el instanceof BraceExprToken)
            break;
        if (current != null && current.getAssociation() == Association.RIGHT && !current.isBinary() && prev instanceof OperatorExprToken)
            break;
        boolean flush = current == null || elPrior == 1 || (isRightOperator ? elPrior > prior : elPrior <= prior);
        if (flush) {
            stack.pop();
            list.add(el);
        } else {
            break;
