Class TimePeriodValues

java.lang.Object

org.jfree.data.general.Series

org.jfree.data.time.TimePeriodValues

All Implemented Interfaces:

Serializable, Cloneable

public class TimePeriodValues
extends Series
implements Serializable

A structure containing zero, one or many TimePeriodValue instances. The time periods can overlap, and are maintained in the order that they are added to the collection.

This is similar to the TimeSeries class, except that the time periods can have irregular lengths.

Constructor Detail

TimePeriodValues

public TimePeriodValues(String name)

Creates a new (empty) collection of time period values.

Parameters:

name - the name of the series (null not permitted).

TimePeriodValues

public TimePeriodValues(String name,
                        String domain,
                        String range)

Creates a new time series that contains no data.

Descriptions can be specified for the domain and range. One situation where this is helpful is when generating a chart for the time series - axis labels can be taken from the domain and range description.

Parameters:

name - the name of the series (null not permitted).

domain - the domain description.

range - the range description.

Method Detail

getDomainDescription

public String getDomainDescription()

Returns the domain description.

Returns:

The domain description (possibly null).

See Also:

getRangeDescription(), setDomainDescription(String)

setDomainDescription

public void setDomainDescription(String description)

Sets the domain description and fires a property change event (with the property name Domain if the description changes).

Parameters:

description - the new description (null permitted).

See Also:

getDomainDescription()

getRangeDescription

public String getRangeDescription()

Returns the range description.

Returns:

The range description (possibly null).

See Also:

getDomainDescription(), setRangeDescription(String)

setRangeDescription

public void setRangeDescription(String description)

Sets the range description and fires a property change event with the name Range.

Parameters:

description - the new description (null permitted).

See Also:

getRangeDescription()

getItemCount

public int getItemCount()

Returns the number of items in the series.

Specified by:

getItemCount in class Series

Returns:

The item count.

getDataItem

public TimePeriodValue getDataItem(int index)

Returns one data item for the series.

Parameters:

index - the item index (in the range 0 to getItemCount() - 1).

Returns:

One data item for the series.

getTimePeriod

public TimePeriod getTimePeriod(int index)

Returns the time period at the specified index.

Parameters:

index - the item index (in the range 0 to getItemCount() - 1).

Returns:

The time period at the specified index.

See Also:

getDataItem(int)

getValue

public Number getValue(int index)

Returns the value at the specified index.

Parameters:

index - the item index (in the range 0 to getItemCount() - 1).

Returns:

The value at the specified index (possibly null).

See Also:

getDataItem(int)

add

public void add(TimePeriodValue item)

Adds a data item to the series and sends a SeriesChangeEvent to all registered listeners.

Parameters:

item - the item (null not permitted).

add

public void add(TimePeriod period,
                double value)

Adds a new data item to the series and sends a SeriesChangeEvent to all registered listeners.

Parameters:

period - the time period (null not permitted).

value - the value.

See Also:

add(TimePeriod, Number)

add

public void add(TimePeriod period,
                Number value)

Adds a new data item to the series and sends a SeriesChangeEvent to all registered listeners.

Parameters:

period - the time period (null not permitted).

value - the value (null permitted).

update

public void update(int index,
                   Number value)

Updates (changes) the value of a data item and sends a SeriesChangeEvent to all registered listeners.

Parameters:

index - the index of the data item to update.

value - the new value (null not permitted).

delete

public void delete(int start,
                   int end)

Deletes data from start until end index (end inclusive) and sends a SeriesChangeEvent to all registered listeners.

Parameters:

start - the index of the first period to delete.

end - the index of the last period to delete.

equals

public boolean equals(Object obj)

Tests the series for equality with another object.

Overrides:

equals in class Series

Parameters:

obj - the object (null permitted).

Returns:

true or false.

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class Series

Returns:

The hashcode

clone

public Object clone()
             throws CloneNotSupportedException

Returns a clone of the collection.

Notes:

• no need to clone the domain and range descriptions, since String object is immutable;
• we pass over to the more general method createCopy(start, end).

Overrides:

clone in class Series

Returns:

A clone of the time series.

Throws:

CloneNotSupportedException - if there is a cloning problem.

createCopy

public TimePeriodValues createCopy(int start,

                            throws CloneNotSupportedException

Creates a new instance by copying a subset of the data in this collection.

Parameters:

start - the index of the first item to copy.

end - the index of the last item to copy.

Returns:

A copy of a subset of the items.

Throws:

CloneNotSupportedException - if there is a cloning problem.

getMinStartIndex

Returns the index of the time period with the minimum start milliseconds.

Returns:

The index.

getMaxStartIndex

public int getMaxStartIndex()

Returns the index of the time period with the maximum start milliseconds.

Returns:

The index.

public int getMinEndIndex()

Returns the index of the time period with the minimum end milliseconds.

Returns:

The index.

getMaxEndIndex

public int getMaxEndIndex()

Returns the index of the time period with the maximum end milliseconds.
