public Unit<?> parse(CharSequence csq, ParsePosition cursor) throws ParserException {
    // Parsing reads the whole character sequence from the parse position.
    int start = cursor.getIndex();
    int end = csq.length();
    if (end <= start) {
        return AbstractUnit.ONE;
    }
    String source = csq.subSequence(start, end).toString().trim();
    if (source.length() == 0) {
        return AbstractUnit.ONE;
    }
    try {
        LocalUnitFormatParser parser = new LocalUnitFormatParser(symbolMap, new StringReader(source));
        Unit<?> result = parser.parseUnit();
        cursor.setIndex(end);
        return result;
    } catch (TokenException e) {

        } else {
            cursor.setErrorIndex(start);
        }
        // TODO should we throw
        throw new IllegalArgumentException(e);
    // ParserException here,
    // too?
    } catch (TokenMgrError e) {

Example 10 with ParserException

use of javax.measure.format.ParserException in project sis by apache.

the class UnitFormat method parse.

/**
 * Parses the given text as an instance of {@code Unit}.
 * If the parse completes without reading the entire length of the text, an exception is thrown.
 *
 * <p>The parsing is lenient: symbols can be products or quotients of units like “m∕s”,
 * words like “meters per second”, or authority codes like {@code "urn:ogc:def:uom:EPSG::1026"}.
 * The product operator can be either {@code '.'} (ASCII) or {@code '⋅'} (Unicode) character.
 * Exponent after symbol can be decimal digits as in “m2” or a superscript as in “m²”.</p>
 *
 * <p>The default implementation delegates to
 * <code>{@linkplain #parse(CharSequence, ParsePosition) parse}(symbols, new ParsePosition(0))</code>
 * and verifies that all non-white characters have been parsed.</p>
 *
 * @param  symbols  the unit symbols or URI to parse.
 * @return the unit parsed from the specified symbols.
 * @throws ParserException if a problem occurred while parsing the given symbols.
 *
 * @see Units#valueOf(String)
