Since: 1.0.3
Field Summary | |
---|---|
protected List | data Storage for the data items in the series. |
Constructor Summary | |
---|---|
ComparableObjectSeries(Comparable key)
Creates a new empty series. | |
ComparableObjectSeries(Comparable key, boolean autoSort, boolean allowDuplicateXValues)
Constructs a new series that contains no data. |
Method Summary | |
---|---|
protected void | add(Comparable x, Object y)
Adds new data to the series and sends a SeriesChangeEvent to
all registered listeners.
|
protected void | add(Comparable x, Object y, boolean notify)
Adds new data to the series and, if requested, sends a
SeriesChangeEvent to all registered listeners.
|
protected void | add(ComparableObjectItem item, boolean notify)
Adds a data item to the series and, if requested, sends a
SeriesChangeEvent to all registered listeners.
|
protected void | clear()
Removes all data items from the series. |
protected void | delete(int start, int end)
Deletes a range of items from the series and sends a
SeriesChangeEvent to all registered listeners.
|
boolean | equals(Object obj)
Tests this series for equality with an arbitrary object.
|
boolean | getAllowDuplicateXValues()
Returns a flag that controls whether duplicate x-values are allowed.
|
boolean | getAutoSort()
Returns the flag that controls whether the items in the series are
automatically sorted. |
protected ComparableObjectItem | getDataItem(int index)
Return the data item with the specified index.
|
int | getItemCount()
Returns the number of items in the series.
|
int | getMaximumItemCount()
Returns the maximum number of items that will be retained in the series.
|
int | hashCode()
Returns a hash code.
|
int | indexOf(Comparable x)
Returns the index of the item with the specified x-value, or a negative
index if the series does not contain an item with that x-value. |
protected ComparableObjectItem | remove(int index)
Removes the item at the specified index and sends a
SeriesChangeEvent to all registered listeners.
|
ComparableObjectItem | remove(Comparable x)
Removes the item with the specified x-value and sends a
SeriesChangeEvent to all registered listeners.
|
void | setMaximumItemCount(int maximum)
Sets the maximum number of items that will be retained in the series.
|
protected void | update(Comparable x, Object y)
Updates an item in the series.
|
protected void | updateByIndex(int index, Object y)
Updates the value of an item in the series and sends a
SeriesChangeEvent to all registered listeners.

Parameters: key the series key (null
not permitted).
Parameters: key the series key (null
not permitted). autoSort a flag that controls whether or not the items in the
series are sorted. allowDuplicateXValues a flag that controls whether duplicate
x-values are allowed.
Throws an exception if the x-value is a duplicate AND the allowDuplicateXValues flag is false.
Parameters: x the x-value (null
not permitted). y the y-value (null
permitted).
Throws an exception if the x-value is a duplicate AND the allowDuplicateXValues flag is false.
Parameters: x the x-value (null
not permitted). y the y-value (null
permitted). notify a flag the controls whether or not a
SeriesChangeEvent is sent to all registered
listeners.
Parameters: item the (x, y) item (null
not permitted). notify a flag that controls whether or not a
SeriesChangeEvent is sent to all registered
listeners.
Parameters: start the start index (zero-based). end the end index (zero-based).
Parameters: obj the object to test against for equality
(null
permitted).
Returns: A boolean.
Returns: A boolean.
Returns: A boolean.
Parameters: index the index.
Returns: The data item with the specified index.
Returns: The item count.
Integer.MAX_VALUE
.
Returns: The maximum item count.
See Also: ComparableObjectSeries
Returns: A hash code.
Parameters: x the x-value (null
not permitted).
Returns: The index.
Parameters: index the index.
Returns: The item removed.
Parameters: x the x-value.
Returns: The item removed.
Typically this value is set before the series is populated with data, but if it is applied later, it may cause some items to be removed from the series (in which case a SeriesChangeEvent will be sent to all registered listeners.
Parameters: maximum the maximum number of items for the series.
Parameters: x the x-value (null
not permitted). y the y-value (null
permitted).
Throws: SeriesException if there is no existing item with the specified x-value.
Parameters: index the item (zero based index). y the new value (null
permitted).
