Example 6 with DoubleIdentifier

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

the class PydmlSyntacticValidator method incrementByOne.

/**
 * Increment lower indices by 1 when translating from PyDML
 * (0-based indexing) to DML (1-based indexing).
 *
 * @param expr expression
 * @param ctx antlr rule context
 * @return expression
 */
private Expression incrementByOne(Expression expr, ParserRuleContext ctx) {
    // Addition and subtraction operator same as DML
    Expression.BinaryOp bop = Expression.getBinaryOp("+");
    Expression retVal = new BinaryExpression(bop);
    ((BinaryExpression) retVal).setLeft(expr);
    ((BinaryExpression) retVal).setRight(new DoubleIdentifier(ctx, 1.0, currentFile));
    setFileLineColumn(retVal, ctx);
    return retVal;

Example 7 with DoubleIdentifier

use of org.apache.sysml.parser.DoubleIdentifier in project incubator-systemml by apache.

the class CommonSyntacticValidator method getConstIdFromString.

    int linePosition = start.getLine();
