* <p><span class="changed_modified_2_0_rev_a">{@link Converter}</span>
* implementation for <code>java.lang.Number</code> values.</p>
*
* <p>The <code>getAsObject()</code> method parses a String into an
* <code>java.lang.Double</code> or <code>java.lang.Long</code>, according
* to the following algorithm:</p>
* <ul>
* <li>If the specified String is null, return
* a <code>null</code>. Otherwise, trim leading and trailing
* whitespace before proceeding.</li>
* <li>If the specified String - after trimming - has a zero length,
* return <code>null</code>.</li>
* <li>If the <code>locale</code> property is not null,
* use that <code>Locale</code> for managing parsing. Otherwise, use the
* <code>Locale</code> from the <code>UIViewRoot</code>.</li>
* <li>If a <code>pattern</code> has been specified, its syntax must conform
* the rules specified by <code>java.text.DecimalFormat</code>. Such
* a pattern will be used to parse, and the <code>type</code> property
* will be ignored.</li>
* <li>If a <code>pattern</code> has not been specified, parsing will be based
* on the <code>type</code> property, which expects a currency, a number,
* or a percent. The parse pattern for currencies, numbers, and
* percentages is determined by calling the
* <code>getCurrencyInstance()</code>, <code>getNumberInstance()</code>,
* or <code>getPercentInstance()</code> method of the
* <code>java.text.NumberFormat</code> class, passing in the selected
* <code>Locale</code>.</li>
* <li>If the <code>integerOnly</code> property has been set to true, only
* the integer portion of the String will be parsed. See the JavaDocs
* for the <code>setParseIntegerOnly()</code> method of the
* <code>java.text.NumberFormat</code> class for more information.</li>
* </ul>
*
* <p>The <code>getAsString()</code> method expects a value of type
* <code>java.lang.Number</code> (or a subclass), and creates a formatted
* String according to the following algorithm:</p>
* <ul>
* <li>If the specified value is null, return a zero-length String.</li>
* <li>If the specified value is a String, return it unmodified.</li>
* <li>If the <code>locale</code> property is not null,
* use that <code>Locale</code> for managing formatting. Otherwise, use the
* <code>Locale</code> from the <code>FacesContext</code>.</li>
* <li>If a <code>pattern</code> has been specified, its syntax must conform
* the rules specified by <code>java.text.DecimalFormat</code>. Such
* a pattern will be used to format, and the <code>type</code> property
* (along with related formatting options described in the next paragraph)
* will be ignored.</li>
* <li>If a <code>pattern</code> has not been specified, formatting will be
* based on the <code>type</code> property, which formats the value as a
* currency, a number, or a percent. The format pattern for currencies,
* numbers, and percentages is determined by calling the
* percentages is determined by calling the
* <code>getCurrencyInstance()</code>, <code>getNumberInstance()</code>,
* or <code>getPercentInstance()</code> method of the
* <code>java.text.NumberFormat</code> class, passing in the selected
* <code>Locale</code>. In addition, the following properties will be
* applied to the format pattern, if specified:
* <ul>
* <li>If the <code>groupingUsed</code> property is <code>true</code>, the
* <code>setGroupingUsed(true)</code> method on the corresponding
* <code>NumberFormat</code> instance will be called.</li>
* <li>The minimum and maximum number of digits in the integer and
* fractional portions of the result will be configured based on
* any values set for the <code>maxFractionDigits</code>,
* <code>maxIntegerDigits</code>, <code>minFractionDigits</code>,
* and <code>minIntegerDigits</code> properties.</li>
* <li>If the type is set to <code>currency</code>, it is also possible
* to configure the currency symbol to be used, using either the
* <code>currencyCode</code> or <code>currencySymbol</code> properties.
* If both are set, the value for <code>currencyCode</code> takes
* precedence on a JDK 1.4 (or later) JVM; otherwise, the value
* for <code>currencySymbol</code> takes precedence.</li>
* </ul></li>
* </ul>
