org.jfree.data.time .TimePeriodValues

TimePeriodValues
public class TimePeriodValues extends Series implements Serializable(Code)
	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.

Field Summary
final protected static String	DEFAULT_DOMAIN_DESCRIPTION Default value for the domain description.
final protected static String	DEFAULT_RANGE_DESCRIPTION Default value for the range description.
final static long	serialVersionUID For serialization.

Constructor Summary
public	TimePeriodValues(String name) Creates a new (empty) collection of time period values.
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.

Method Summary
public void	add(TimePeriodValue item) Adds a data item to the series and sends a SeriesChangeEvent to all registered listeners.
public void	add(TimePeriod period, double value) Adds a new data item to the series and sends a SeriesChangeEvent to all registered listeners.
public void	add(TimePeriod period, Number value) Adds a new data item to the series and sends a SeriesChangeEvent to all registered listeners.
public Object	clone() Returns a clone of the collection.
public TimePeriodValues	createCopy(int start, int end) Creates a new instance by copying a subset of the data in this collection. Parameters: start - the index of the first item to copy. Parameters: end - the index of the last item to copy.
public void	delete(int start, int end) Deletes data from start until end index (end inclusive) and sends a SeriesChangeEvent to all registered listeners.
public boolean	equals(Object obj) Tests the series for equality with another object. Parameters: obj - the object (`null` permitted).
public TimePeriodValue	getDataItem(int index) Returns one data item for the series. Parameters: index - the item index (in the range `0` to `getItemCount() - 1`).
public String	getDomainDescription() Returns the domain description.
public int	getItemCount() Returns the number of items in the series.
public int	getMaxEndIndex() Returns the index of the time period with the maximum end milliseconds.
public int	getMaxMiddleIndex() Returns the index of the time period with the maximum middle milliseconds.
public int	getMaxStartIndex() Returns the index of the time period with the maximum start milliseconds.
public int	getMinEndIndex() Returns the index of the time period with the minimum end milliseconds.
public int	getMinMiddleIndex() Returns the index of the time period with the minimum middle milliseconds.
public int	getMinStartIndex() Returns the index of the time period with the minimum start milliseconds.
public String	getRangeDescription() Returns the range description.
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`).
public Number	getValue(int index) Returns the value at the specified index. Parameters: index - the item index (in the range `0` to `getItemCount() - 1`).
public int	hashCode() Returns a hash code value for the object.
public void	setDomainDescription(String description) Sets the domain description and fires a property change event (with the property name `Domain` if the description changes).
public void	setRangeDescription(String description) Sets the range description and fires a property change event with the name `Range`.
public void	update(int index, Number value) Updates (changes) the value of a data item and sends a SeriesChangeEvent to all registered listeners.

Field Detail

DEFAULT_DOMAIN_DESCRIPTION
final protected static String DEFAULT_DOMAIN_DESCRIPTION(Code)
	Default value for the domain description.

DEFAULT_RANGE_DESCRIPTION
final protected static String DEFAULT_RANGE_DESCRIPTION(Code)
	Default value for the range description.

serialVersionUID
final static long serialVersionUID(Code)
	For serialization.

Constructor Detail

TimePeriodValues
public TimePeriodValues(String name)(Code)
	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)(Code)
	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). Parameters: domain - the domain description. Parameters: range - the range description.

Method Detail

add
public void add(TimePeriodValue item)(Code)
	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)(Code)
	Adds a new data item to the series and sends a SeriesChangeEvent to all registered listeners. Parameters: period - the time period (`null` not permitted). Parameters: value - the value. See Also: TimePeriodValues.add(TimePeriod,Number)

add
public void add(TimePeriod period, Number value)(Code)
	Adds a new data item to the series and sends a SeriesChangeEvent to all registered listeners. Parameters: period - the time period (`null` not permitted). Parameters: value - the value (`null` permitted).

clone

public Object clone() throws CloneNotSupportedException(Code)

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).

A clone of the time series.
throws:
CloneNotSupportedException - if there is a cloning problem.

createCopy
public TimePeriodValues createCopy(int start, int end) throws CloneNotSupportedException(Code)
	Creates a new instance by copying a subset of the data in this collection. Parameters: start - the index of the first item to copy. Parameters: end - the index of the last item to copy. A copy of a subset of the items. throws: CloneNotSupportedException - if there is a cloning problem.

delete
public void delete(int start, int end)(Code)
	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. Parameters: end - the index of the last period to delete.

equals
public boolean equals(Object obj)(Code)
	Tests the series for equality with another object. Parameters: obj - the object (`null` permitted). `true` or `false`.

getDataItem
public TimePeriodValue getDataItem(int index)(Code)
	Returns one data item for the series. Parameters: index - the item index (in the range `0` to `getItemCount() - 1`). One data item for the series.
