Method Detail

getDuration

public double getDuration()

This method is used to retrieve the size of the duration.

Returns:

size of the duration

getUnits

public TimeUnit getUnits()

This method is used to retrieve the type of units the duration is expressed in. The valid types of units are found in the TimeUnit class.

Returns:

type of units

convertUnits

public Duration convertUnits(TimeUnit type,
                             ProjectHeader defaults)

This method provides an approximate conversion between duration units. It does take into account the project defaults for number of hours in a day and a week, but it does not take account of calendar details. The results obtained from it should therefore be treated with caution.

Parameters:

type - target duration type

defaults - project header containing default values

Returns:

new Duration instance

convertUnits

public static Duration convertUnits(double duration,
                                    TimeUnit fromUnits,
                                    TimeUnit toUnits,
                                    ProjectHeader defaults)

This method provides an approximate conversion between duration units. It does take into account the project defaults for number of hours in a day and a week, but it does not take account of calendar details. The results obtained from it should therefore be treated with caution.

Parameters:

duration - duration value

fromUnits - units to convert from

toUnits - units to convert to

defaults - project header containing default values

Returns:

new Duration instance

convertUnits

public static Duration convertUnits(double duration,
                                    TimeUnit fromUnits,
                                    TimeUnit toUnits,
                                    double minutesPerDay,
                                    double minutesPerWeek,
                                    double daysPerMonth)

This method provides an approximate conversion between duration units. It does take into account the project defaults for number of hours in a day and a week, but it does not take account of calendar details. The results obtained from it should therefore be treated with caution.

Parameters:

duration - duration value

fromUnits - units to convert from

toUnits - units to convert to

minutesPerDay - number of minutes per day

minutesPerWeek - number of minutes per week

daysPerMonth - number of days per month

Returns:

new Duration instance

getInstance

public static Duration getInstance(double duration,
                                   TimeUnit type)

Retrieve an Duration instance. Use shared objects to represent common values for memory efficiency.

Parameters:

duration - duration value

type - duration type

Returns:

Duration instance

getInstance

public static Duration getInstance(int duration,
                                   TimeUnit type)

Retrieve an Duration instance. Use shared objects to represent common values for memory efficiency.

Parameters:

duration - duration value

type - duration type

Returns:

Duration instance

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

compareTo

public int compareTo(Duration rhs)

Specified by:

compareTo in interface Comparable<Duration>

toString

public String toString()

Overrides:

toString in class Object
