| hashCode | | public int hashCode()(Code) | | Returns a hash code.
A hash code. |
| insertValue | | public void insertValue(int position, Comparable key, double value)(Code) | | Inserts a new value at the specified position in the dataset or, if
there is an existing item with the specified key, updates the value
for that item and moves it to the specified position.

| insertValue | | public void insertValue(int position, Comparable key, Number value)(Code) | | Inserts a new value at the specified position in the dataset or, if
there is an existing item with the specified key, updates the value
for that item and moves it to the specified position.

| removeValue | | public void removeValue(int index)(Code) | | Removes a value from the collection.
Parameters:
index - the index of the item to remove (in the range 0 to getItemCount() - 1).
throws:
IndexOutOfBoundsException - if index is not withinthe specified range. |
| removeValue | | public void removeValue(Comparable key)(Code) | | Removes a value from the collection. If there is no item with the
specified key, this method does nothing.
Parameters:
key - the item key (null not permitted).
throws:
IllegalArgumentException - if key is null. |
| setValue | | public void setValue(Comparable key, double value)(Code) | | Updates an existing value, or adds a new value to the collection.
Parameters:
key - the key (null not permitted).
