| 14 | * <p> | |
| 15 | * <code>FlyweightEntity</code> is a Flyweight pattern implementation of a | |
| 16 | * singly linked, read-only XML entity. | |
| 17 | * </p> | |
| 18 | * | |
| 19 | * <p> | |
| 20 | * This node could be shared across documents and elements though it does not | |
| 21 | * support the parent relationship. | |
| 22 | * </p> | |
| 23 | * | |
| 24 | * <p> | |
| 25 | * Often this node needs to be created and then the text content added later | |
| 26 | * (for example in SAX) so this implementation allows a call to {@link#setText} | |
| 27 | * providing the entity has no text already. | |
| 28 | * </p> | |
