get_next_interval()

int teca_calendar_util::n_steps_iterator::get_next_interval ( time_point &  first_step, time_point &  last_step  )

overridevirtual

Return a pair of time steps bracketing the current block of n steps. Both returned time steps belong to the current block of steps.

Implements teca_calendar_util::interval_iterator.

initialize() [1/4]

int teca_calendar_util::n_steps_iterator::initialize ( const const_p_teca_variant_array &  t, const std::string &  units, const std::string &  calendar, long  first_step, long  last_step  )

overridevirtual

Initialize the iterator.

Parameters

[in]	t	An array of time values
[in]	units	A string units of the time values
[in]	calendar	A string name of the calendar system
[in]	first_step	the first step to include in the series or 0 to use all
[in]	last_step	the last step to include in the series or -1 to use all

Returns

0 if successfully initialized

Implements teca_calendar_util::interval_iterator.

initialize() [2/4]

virtual int teca_calendar_util::interval_iterator::initialize

Initialize the iterator.

Parameters

[in]	t	An array of time values
[in]	units	A string units of the time values
[in]	calendar	A string name of the calendar system
[in]	first_step	the first step to include in the series or 0 to use all
[in]	last_step	the last step to include in the series or -1 to use all

Returns

0 if successfully initialized

initialize() [3/4]

virtual int teca_calendar_util::interval_iterator::initialize

Initialize the iterator from a metadata object following the conventions defined by the teca_cf_reader.

Returns

0 if successfully initialized

initialize() [4/4]

virtual int teca_calendar_util::interval_iterator::initialize

Initialize the iterator from a metadata object following the conventions defined by the teca_cf_reader.

Parameters

[in]	md	a metadata object
[in]	first_step	the first step to include in the series or 0 to use all
[in]	last_step	the last step to include in the series or -1 to use all

Returns

0 if successfully initialized

is_valid()

bool teca_calendar_util::n_steps_iterator::is_valid ( ) const

overridevirtual

return true if there are more time steps in the sequence

Implements teca_calendar_util::interval_iterator.
