Method new()

Initializes object

Usage

GMLTimePeriod$new(xml = NULL, beginPosition = NULL, endPosition = NULL)

Arguments

xml

beginPosition

object of class numeric, Date or POSIXct-class

endPosition

object of class numeric, Date or POSIXct-class

---

Method setBeginPosition()

Set begin position

Usage

GMLTimePeriod$setBeginPosition(
  beginPosition = NULL,
  frame = NULL,
  calendarEraName = NULL,
  indeterminatePosition = NULL
)

Arguments

beginPosition

object of class numeric, Date or POSIXct-class

)

Arguments

years

years

months

months

days

days

hours

hours

mins

mins

secs

secs

---

Method clone()

The objects of this class are cloneable with this method.

Usage

GMLTimePeriod$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
