Class ColumnPeriod

java.lang.Object

com.ihr.xbrl.dts.ColumnPeriod

public class ColumnPeriod
extends java.lang.Object

This is a class representing a logical reporting period. Logical reporting period includes a start position and an end position.

The difference with an XBRLPeriod is that the interpretation of the reporting date for instant data. Instant data belongs to a period that may not match with the data in the XBRLPeriod context.

A ColumnPeriod does not contains contexts associated. Contexts are associated to FactColumns. There is a one to one relationship between a ColumnPeriod and a Factcolumns object.

Constructor Detail

ColumnPeriod

public ColumnPeriod(HasBoySupport boyManager,
            java.util.GregorianCalendar pStart,
            int dateStep)

Instantiates a new column period.

Parameters:

boyManager - the boy manager

pStart - the start

dateStep - the date step

ColumnPeriod

public ColumnPeriod(HasBoySupport boyManager,

            int dateStep,
            HandleDateStep.InstantMode instantMode)

Creates a column period using an XBRLPeriod, as source. If the period is forever, a "forever" column is created. If the column is duration, the context start date is used after normalization and the value of the dateStep is used during the normalization phase.

Parameters:

boyManager - provides information about the month calendar a fiscal year begins.

p - XBRLPeriod

dateStep - constant indicating the period length.

instantMode - for instant values this is the matching strategy with duration contexts.

Parameters:

boyManager - the boy manager

pStart - Initial date for the column period

pEnd - End date for the column period

ColumnPeriod
