Detailed Description

Time scale row class.

Library: views

This class implements methods from the class IlvTimeScaleRow to provide a complete scale displaying yearly intervals. By default, each yearly interval is displayed with a text formatted using java.text.SimpleDateFormat created with the "yyy" string. The exact result depends on the system Locale, in English "2002" for January 18th, 2002.

Constructor & Destructor Documentation

IlvYearTimeScaleRow::IlvYearTimeScaleRow

(

IlvTimeScale *

parent

)

Constructor.

Creates and initializes an IlvYearTimeScaleRow object.

Member Function Documentation

virtual IlvTimeScaleRow* IlvYearTimeScaleRow::cloneType ( IlvTimeScale *  scale ) const

protectedvirtual

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 IlvYearTimeScaleRow::getType ( ) const

virtual

Returns the type of the IlvTimeScaleRow.

Returns

The type of the IlvTimeScaleRow.

Implements IlvTimeScaleRow.

virtual IlDate IlvYearTimeScaleRow::incrementTime ( IlDate  dateval )

virtual

Increments the specified date by one year.

For example, the incremented date of January 14th, 2002 is January 14th, 2003.

Parameters

dateval

The date to increment.

Implements IlvTimeScaleRow.

virtual IlDate IlvYearTimeScaleRow::previousUnitTime ( IlDate  dateval )

virtual

Returns the previous unit value of the year relative to the specified date.

For example, the previous unit time of January 14th, 2002 is January 1st, 2002.

Parameters

dateval

The date to floor.

Implements IlvTimeScaleRow.

virtual void IlvYearTimeScaleRow::read ( IlvInputFile &  infile )

virtual

Reads the time scale row description from an input file.

Parameters

infile

The input file.

Reimplemented from IlvTimeScaleRow.

virtual void IlvYearTimeScaleRow::write ( IlvOutputFile &  outfile ) const

virtual

Saves the time scale row in an output file.

Parameters

outfile

The output file.

Reimplemented from IlvTimeScaleRow.
