Examples with BooleanIdentifier org.apache.sysml.parser.BooleanIdentifier used on opensource projects

Example 1 with BooleanIdentifier

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

the class CommonSyntacticValidator method getConstIdFromString.

protected ConstIdentifier getConstIdFromString(String varValue, Token start) {
    int linePosition = start.getLine();
    int charPosition = start.getCharPositionInLine();
    // Compare to "True/TRUE"
    if (varValue.equals(trueStringLiteral()))
        return new BooleanIdentifier(true, currentFile, linePosition, charPosition, linePosition, charPosition);
    // Compare to "False/FALSE"
    if (varValue.equals(falseStringLiteral()))
        return new BooleanIdentifier(false, currentFile, linePosition, charPosition, linePosition, charPosition);
    // Also the alternative of Ints.tryParse and falling back to double would not be lossless in all cases. 
    try {
        long lval = Long.parseLong(varValue);
        return new IntIdentifier(lval, currentFile, linePosition, charPosition, linePosition, charPosition);
    } catch (Exception ex) {
    //continue
    }
    // NOTE: we use exception handling instead of Doubles.tryParse for backwards compatibility with guava <14.0
    try {
        double dval = Double.parseDouble(varValue);
        return new DoubleIdentifier(dval, currentFile, linePosition, charPosition, linePosition, charPosition);
    } catch (Exception ex) {
    //continue
    }
    // Otherwise it is a string literal (optionally enclosed within single or double quotes)
    String val = "";
    String text = varValue;
    if ((text.startsWith("\"") && text.endsWith("\"")) || (text.startsWith("\'") && text.endsWith("\'"))) {
        if (text.length() > 2) {
            val = extractStringInQuotes(text, true);
        }
    } else {
        // the commandline parameters can be passed without any quotes
        val = extractStringInQuotes(text, false);
    }
    return new StringIdentifier(val, currentFile, linePosition, charPosition, linePosition, charPosition);
}

Example 2 with BooleanIdentifier

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

the class CommonSyntacticValidator method booleanIdentifierHelper.

protected void booleanIdentifierHelper(ParserRuleContext ctx, boolean val, ExpressionInfo info) {
    int linePosition = ctx.start.getLine();
    int charPosition = ctx.start.getCharPositionInLine();
    info.expr = new BooleanIdentifier(val, currentFile, linePosition, charPosition, linePosition, charPosition);
    setFileLineColumn(info.expr, ctx);
