Method Detail

of

public static HolidayCalendarId of(java.lang.String uniqueName)

Obtains an instance from the specified unique name.

The name uniquely identifies the calendar. The HolidayCalendar is resolved from ReferenceData when required.

It is possible to combine two or more calendars using the '+' symbol. For example, 'GBLO+USNY' will combine the separate 'GBLO' and 'USNY' calendars. The resulting identifier will have the individual identifiers normalized into alphabetical order.

Parameters:

uniqueName - the unique name

Returns:

the identifier

defaultByCurrency

public static HolidayCalendarId defaultByCurrency(Currency currency)

Gets the default calendar for a currency.

This uses data from HolidayCalendarDefaultData.ini to provide a default.

Parameters:

currency - the currency to find the default for

Returns:

the holiday calendar

Throws:

java.lang.IllegalArgumentException - if there is no default for the currency

getName

public java.lang.String getName()

Gets the name that uniquely identifies this calendar.

This name is used in serialization and can be parsed using of(String).

Specified by:

getName in interface Named

Returns:

the unique name

getReferenceDataType

public java.lang.Class<HolidayCalendar> getReferenceDataType()

Gets the type of data this identifier refers to.

A HolidayCalendarId refers to a HolidayCalendar.

Specified by:

getReferenceDataType in interface ReferenceDataId<HolidayCalendar>

Returns:

the type of the reference data this identifier refers to

resolve

public HolidayCalendar resolve(ReferenceData refData)

Resolves this identifier to a holiday calendar using the specified reference data.

This returns an instance of HolidayCalendar that can perform calculations.

Resolved objects may be bound to data that changes over time, such as holiday calendars. If the data changes, such as the addition of a new holiday, the resolved form will not be updated. Care must be taken when placing the resolved form in a cache or persistence layer.

Specified by:

resolve in interface Resolvable<HolidayCalendar>

Parameters:

refData - the reference data, used to resolve the reference

Returns:

the resolved holiday calendar

Throws:

ReferenceDataNotFoundException - if the identifier is not found

queryValueOrNull

public HolidayCalendar queryValueOrNull(ReferenceData refData)

Description copied from interface: ReferenceDataId

Low-level method to query the reference data value associated with this identifier, returning null if not found.

This is a low-level method that obtains the reference data value, returning null instead of an error. Applications should use ReferenceData.getValue(ReferenceDataId) in preference to this method.

Specified by:

queryValueOrNull in interface ReferenceDataId<HolidayCalendar>

Parameters:

refData - the reference data to lookup the value in

Returns:

the reference data value, null if not found

combinedWith

public HolidayCalendarId combinedWith(HolidayCalendarId other)

Combines this holiday calendar identifier with another.

The resulting calendar will declare a day as a business day if it is a business day in both source calendars.

Parameters:

other - the other holiday calendar identifier

Returns:

the combined holiday calendar identifier

equals

public boolean equals(java.lang.Object obj)

Checks if this identifier equals another identifier.

The comparison checks the name.

Overrides:

equals in class java.lang.Object

Returns:

true if equal

hashCode

hashCode in class java.lang.Object

Returns:

the hash code

toString
