Class BusinessCalendarXMLParser

java.lang.Object
io.deephaven.time.calendar.BusinessCalendarXMLParser
public final class BusinessCalendarXMLParser extends Object
A parser for reading business calendar XML files.

Business calendar XML files should be formatted as: 

 
 <calendar>
     <name>USNYSE</name>
     <!-- Optional description -->
     <description>New York Stock Exchange Calendar</description>
     <timeZone>America/New_York</timeZone>
     <default>
          <businessTime><open>09:30</open><close>16:00</close></businessTime>
          <weekend>Saturday</weekend>
          <weekend>Sunday</weekend>
      </default>
      <!-- Optional firstValidDate.  Defaults to the first holiday. -->
      <firstValidDate>1999-01-01</firstValidDate>
      <!-- Optional lastValidDate.  Defaults to the first holiday. -->
      <lastValidDate>2003-12-31</lastValidDate>
      <holiday>
          <date>1999-01-01</date>
      </holiday>
      <holiday>
          <date>2002-07-05</date>
          <businessTime>
              <open>09:30</open>
              <close>13:00</close>
          </businessTime>
      </holiday>
 </calendar>
In addition, legacy XML files are supported. These files have dates formatted as `yyyyMMdd` instead of ISO-8601 `yyy-MM-dd`. Additionally, legacy uses `businessPeriod` tags in place of the `businessTime` tags. 
 
 <!-- Current format -->
 <businessTime><open>09:30</open><close>16:00</close></businessTime>
 
 
 
 <!-- Legacy format -->
 <businessPeriod>09:30,16:00</businessPeriod>
The legacy format may be deprecated in a future release.
