virtual IlvTimeScaleRow* IlvHalfDayTimeScaleRow::cloneType

(

IlvTimeScale *

scale

)

const [protected, virtual]

Returns an object of the same type.

This method should be implemented by subclasses. It must return an object of the same type as the object on which the method is called, attached to the given IlvTimeScale.

Parameters:

scale

The IlvTimeScale on which the row is attached.

Returns:

A newly allocated object of the same type as the object on which the method is called.

Implements IlvTimeScaleRow.

virtual IlvTimeScaleRowFactory::rowtype IlvHalfDayTimeScaleRow::getType

(

)

const [virtual]

Returns the type of the IlvTimeScaleRow.

Returns:

The type of the IlvTimeScaleRow.

Implements IlvTimeScaleRow.

virtual IlDate IlvHalfDayTimeScaleRow::incrementTime

(

IlDate

dateval

)

[virtual]

Increments the specified date by half a day.

For example, the incremented date of January 14th, 2002, 8:12:34 AM is January 14th, 2002, 8:12:34 PM.

Parameters:

dateval

The date to increment.

Implements IlvTimeScaleRow.

virtual IlDate IlvHalfDayTimeScaleRow::previousUnitTime

(

IlDate

dateval

)

[virtual]

Returns the previous unit time value of half a day relative to the specified date.

For example, the previous unit time of January 14th, 2002, 8:12:34 AM is January 14th, 2002, 0:00:00 AM.

Parameters:

dateval

The date to floor.

Implements IlvTimeScaleRow.

virtual void IlvHalfDayTimeScaleRow::read

(

IlvInputFile &

infile

)

[virtual]

Reads the time scale row description from an input file.

Parameters:

infile

The input file.

Reimplemented from IlvTimeScaleRow.

virtual void IlvHalfDayTimeScaleRow::write

(

IlvOutputFile &

outfile

)

const [virtual]

Saves the time scale row in an output file.

Parameters:

outfile

The output file.

Reimplemented from IlvTimeScaleRow.
