| Modifier and Type | Method and Description |
|---|---|
void |
close()
Method to close the results, making the results unusable thereafter.
|
protected void |
closeResults()
Internal method to close the ResultSet.
|
protected void |
closingConnection()
Method called to inform the query result that the connection is being closed so perform
any required operations now, or rest in peace.
|
boolean |
contains(Object o)
Method to check if the specified object is contained in this result.
|
boolean |
containsAll(Collection c)
Method to check if all of the specified objects are contained here.
|
boolean |
equals(Object o) |
E |
get(int index)
Method to retrieve a particular element from the list.
|
protected int |
getSizeUsingMethod()
Method to get the size using the "resultSizeMethod".
|
int |
hashCode() |
void |
initialise() |
boolean |
isEmpty()
Accessor for whether there are any results.
|
Iterator<E> |
iterator()
Accessor for an iterator for the results.
|
ListIterator<E> |
listIterator()
Accessor for an iterator for the results.
|
protected E |
nextResultSetElement()
Accessor for the next object from the ResultSet.
|
Object[] |
toArray()
Method to return the results as an array.
|
Object[] |
toArray(Object[] a)
Method to return the results as an array.
|
protected Object |
writeReplace()
Handle serialisation by returning a java.util.ArrayList of all of the results for this query
after disconnecting the query which has the consequence of enforcing the load of all objects.
