Constructor Detail

DateHeadingImpl

public DateHeadingImpl(DateHeading sourceHeading)

Because DateHeadings tend to generate their forward headings upon request, this constructor will not copy any forward headings of the source Heading. The constructed DateHeadingImpl will have the same start and end instants as the source Heading, but define its own forward headings of unit years, months, and days.

                       java.util.Date endInstant)

Method Detail
