Method Detail

factory

public static CoordinateAxis1DTime factory(NetcdfDataset ncd,
                           VariableDS org,
                           Formatter errMessages)
                                    throws IOException

Throws:

IOException

copy

protected Variable copy()

Overrides:

copy in class CoordinateAxis1D

section

public CoordinateAxis1D 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

public CalendarDate getCalendarDate(int idx)

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 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 Exception

only if isRegular() LOOK REDO

Returns:

time unit

Throws:

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

• i, if time(i) <= d < time(i+1).
• 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:

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 List<CalendarDate> getCalendarDates()

getTimeDates

public Date[] getTimeDates()

Deprecated. use getCalendarDates() to correctly interpret calendars

getTimeDate

public Date getTimeDate(int idx)

Deprecated. use getCalendarDate()

getDateRange

public DateRange getDateRange()

Deprecated. use getCalendarDateRange()

findTimeIndexFromDate

public int findTimeIndexFromDate(Date d)

Deprecated. use findTimeIndexFromCalendarDate

hasTime

public boolean hasTime(Date date)

Deprecated. use hasCalendarDate
