Method Detail

localDateToString

public static String localDateToString(LocalDate localDate)

Turns a given LocalDate value into a String suitable for storing and searching in Lucene.

The date is stored as "YYYYMMDD". If the date is null we store "99999999" which causes nulls to sort to the end. (This is traditional JIRA behaviour)

Parameters:

localDate - the date to be converted. May be null

Returns:

a string representing the date

stringToLocalDate

public static LocalDate stringToLocalDate(String indexValue)

dateToString

public static String dateToString(Date date)

Turns a given date-time (point in time) value into a String suitable for storing and searching in Lucene.

The date-time is stored as the number of seconds. If the date is null we store the encoded form of Long.MAX_VALUE which causes nulls to sort to the end. (This is traditional JIRA behaviour)

Parameters:

date - the date to be converted. May be null

Returns:

a string representing the number of seconds

stringToDate

public static Date stringToDate(String s)
