Class MailDateFormat.AbstractDateParser

java.lang.Object

javax.mail.internet.MailDateFormat.AbstractDateParser

Direct Known Subclasses:

MailDateFormat.Rfc2822StrictParser

Enclosing class:

MailDateFormat

private abstract static class MailDateFormat.AbstractDateParser
extends java.lang.Object

This class provides the building blocks for date parsing.

It has the following invariants:

• no exceptions are thrown, except for java.text.ParseException from parse* methods
• when parse* throws ParseException OR get* returns INVALID_CHAR OR skip* returns false OR peek* is invoked, then pos.getIndex() on method exit is the same as it was on method entry
