                                           VariableDS org,
                                           java.util.Formatter errMessages)
                                    throws java.io.IOException

Throws:

java.io.IOException

copy

protected Variable copy()

Overrides:

copy in class CoordinateAxis1D

section

public CoordinateAxis1DTime section(Range r)
                             throws InvalidRangeException

Description copied from class: CoordinateAxis1D

Create a new CoordinateAxis1D as a section of this CoordinateAxis1D.

Overrides:

section in class CoordinateAxis1D

Parameters:

r - the section range

Returns:

a new CoordinateAxis1D as a section of this CoordinateAxis1D

Throws:

InvalidRangeException - if IllegalRange

getCalendarDate

Get the the ith CalendarDate.

Parameters:

idx - index

Returns:

the ith CalendarDate

getCalendarDateRange

public CalendarDateRange getCalendarDateRange()

Get calendar date range

Returns:

calendar date range

getNames

public java.util.List<NamedObject> getNames()

Description copied from class: CoordinateAxis1D

Get the list of names, to be used for user selection. The ith one refers to the ith coordinate.

Overrides:

getNames in class CoordinateAxis1D

Returns:

List of ucar.nc2.util.NamedObject, or empty list.

getTimeResolution

public TimeUnit getTimeResolution()
                           throws java.lang.Exception

only if isRegular() LOOK REDO

Returns:

time unit

Throws:

java.lang.Exception - on bad unit string

findTimeIndexFromCalendarDate

public int findTimeIndexFromCalendarDate(CalendarDate d)

Given a Date, find the corresponding time index on the time coordinate axis. Can only call this is hasDate() is true. This will return

• 0, if d < time(0)
• n-1, if d > time(n-1), where n is length of time coordinates

Parameters:

d - date to look for

Returns:

corresponding time index on the time coordinate axis

Throws:

java.lang.UnsupportedOperationException - is no time axis or isDate() false

hasCalendarDate

public boolean hasCalendarDate(CalendarDate date)

See if the given CalendarDate appears as a coordinate

Parameters:

date - test this

Returns:

true if equals a coordinate

getCalendarDates

public java.util.List<CalendarDate> getCalendarDates()

Get the list of datetimes in this coordinate as CalendarDate objects.

Returns:

list of CalendarDates.
