Example 5 with IntIdentifier

use of org.apache.sysml.parser.IntIdentifier in project systemml by apache.

the class CommonSyntacticValidator method constIntIdExpressionHelper.

protected void constIntIdExpressionHelper(ParserRuleContext ctx, ExpressionInfo me) {
    try {
        long val = Long.parseLong(ctx.getText());
        me.expr = new IntIdentifier(ctx, val, currentFile);
    } catch (Exception e) {
        notifyErrorListeners("cannot parse the int value: \'" + ctx.getText() + "\'", ctx.getStart());
        return;
    }
