Timeline (JFreeChart Class Library (version 1.0.14))

All Known Implementing Classes:

SegmentedTimeline
```
public interface Timeline
```
An interface that defines the contract for a Timeline.
A Timeline will present a series of values to be used for an axis. Each Timeline must provide transformation methods between domain values and timeline values. In theory many transformations are possible. This interface has been implemented completely in SegmentedTimeline.
A timeline can be used as parameter to a DateAxis to define the values that this axis supports. As an example, the SegmentedTimeline implements a timeline formed by segments of equal length (ex. days, hours, minutes) where some segments can be included in the timeline and others excluded. Therefore timelines like "working days" or "working hours" can be created where non-working days or non-working hours respectively can be removed from the timeline, and therefore from the axis. This creates a smooth plot with equal separation between all included segments.
Because Timelines were created mainly for Date related axis, values are represented as longs instead of doubles. In this case, the domain value is just the number of milliseconds since January 1, 1970, 00:00:00 GMT as defined by the getTime() method of Date.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`boolean`	`containsDomainRange(java.util.Date fromDate, java.util.Date toDate)` Returns `true` if a range of dates are contained in the timeline.
`boolean`	`containsDomainRange(long fromMillisecond, long toMillisecond)` Returns `true` if a range of values are contained in the timeline.
`boolean`	`containsDomainValue(java.util.Date date)` Returns `true` if a date is contained in the timeline values.
`boolean`	`containsDomainValue(long millisecond)` Returns `true` if a value is contained in the timeline values.
`long`	`toMillisecond(long timelineValue)` Translates a value relative to this timeline into a domain value.
`long`	`toTimelineValue(java.util.Date date)` Translates a date into a value on this timeline.
`long`	`toTimelineValue(long millisecond)` Translates a millisecond (as defined by java.util.Date) into an index along this timeline.

- Method Detail
  - toTimelineValue
```
long toTimelineValue(long millisecond)
```
    Translates a millisecond (as defined by java.util.Date) into an index along this timeline.
    
    Parameters:
    
    millisecond - the millisecond.
    
    Returns:
    
    A timeline value.
  - toTimelineValue
```
long toTimelineValue(java.util.Date date)
```
    Translates a date into a value on this timeline.
    
    Parameters:
    
    date - the date.
    
    Returns:
    
    A timeline value
  - toMillisecond
```
long toMillisecond(long timelineValue)
```
    Translates a value relative to this timeline into a domain value. The domain value obtained by this method is not always the same domain value that could have been supplied to translateDomainValueToTimelineValue(domainValue). This is because the original tranformation may not be complete reversable.
    
    Parameters:
    
    timelineValue - a timeline value.
    
    Returns:
    
    A domain value.

    SegmentedTimeline
  - containsDomainValue
```
boolean containsDomainValue(long millisecond)
```
    Returns true if a value is contained in the timeline values.
    
    Parameters:
    
    millisecond - the millisecond.
    
    Returns:
    
    true if value is contained in the timeline and false otherwise.
  - containsDomainValue
```
boolean containsDomainValue(java.util.Date date)
```
    Returns true if a date is contained in the timeline values.
    
    Parameters:
    
    date - the date to verify.
    
    Returns:
    
    true if value is contained in the timeline and false otherwise.
  - containsDomainRange
```
boolean containsDomainRange(long fromMillisecond,
                            long toMillisecond)
```
    Returns true if a range of values are contained in the timeline.
    
    Parameters:
    
    fromMillisecond - the start of the range to verify.
    
    toMillisecond - the end of the range to verify.
    
    Returns:
    
    true if the range is contained in the timeline or false otherwise
  - containsDomainRange
```
boolean containsDomainRange(java.util.Date fromDate,
                            java.util.Date toDate)
```
    Returns true if a range of dates are contained in the timeline.
    
    Parameters:
    
    fromDate - the start of the range to verify.
    
    toDate - the end of the range to verify.
    
    Returns:
    
    true if the range is contained in the timeline or false otherwise
