Method Details

getTrendDateString

public static String getTrendDateString(org.apache.cayenne.DataRow dataRow,
 String periodType)

This method creates a date string used to reference trend data for a specific period. This method is used internally by DAOs and may be modified without warning. The resulting strings are not suitable for display but merely for providing a value for use as a key in maps and the like. Also note that the year is not used, and so the strings are not suitable for data spanning a year or more.

Parameters:

dataRow - the data row holding period information in the numeric fields "month", "day" and (if grouping by hour) "hour"

periodType - PERIOD_TYPE_DAY or PERIOD_TYPE_HOUR

Returns:

a string identifying the period for the data row and period type, e.g. "08-22" for day-based data or "08-22-15" for hour-based data corresponding to August 22, 15:00

getTrendDateString

public static String getTrendDateString(org.joda.time.DateTime date,
 String periodType)

This method creates a date string used to reference trend data for a specific period. This method is used internally by DAOs and may be modified without warning. The resulting strings are not suitable for display but merely for providing a value for use as a key in maps and the like. Also note that the year is not used, and so the strings are not suitable for data spanning a year or more.

Parameters:

date - the date/time holding period information

periodType - PERIOD_TYPE_DAY or PERIOD_TYPE_HOUR

Returns:

a string identifying the period for the date and period type, e.g. "08-22" for day-based data or "08-22-15" for hour-based data corresponding to August 22, 15:00
