 com.sleepycat.persist.impl.VisitedObjects
| VisitedObjects | | class VisitedObjects (Code) | | Keeps track of a set of visited objects and their corresponding offset in a
byte array. This uses a resizable int array for speed and simplicity. If
in the future the array resizing or linear search are performance issues, we
could try using an IdentityHashMap instead.

| Method Summary | |
| int | add(Object o, int offset)
Adds a visited object and offset, growing the visited arrays as needed. | | Object | getObject(int offset)
Returns the visited object for a given offset, or null if never visited. | | int | getOffset(Object o)
Returns the offset for a visited object, or -1 if never visited. | | void | replaceObject(Object existing, Object replacement)
Replaces a given object in the list. | | void | setObject(int index, Object o)
Sets the object for an existing slot index. | | void | setOffset(int index, int offset)
Sets the offset for an existing slot index. |
| PRI_KEY_VISITED_OFFSET | | final static int PRI_KEY_VISITED_OFFSET(Code) | | |
| PROHIBIT_NESTED_REF_MSG | | final static String PROHIBIT_NESTED_REF_MSG(Code) | | |
| PROHIBIT_REF_OBJECT | | final static Object PROHIBIT_REF_OBJECT(Code) | | |
| PROHIBIT_REF_OFFSET | | final static int PROHIBIT_REF_OFFSET(Code) | | |
| VisitedObjects | | VisitedObjects()(Code) | | Creates an empty set.
|
| add | | int add(Object o, int offset)(Code) | | Adds a visited object and offset, growing the visited arrays as needed.
the index of the new slot. |
| getObject | | Object getObject(int offset)(Code) | | Returns the visited object for a given offset, or null if never visited.
|
| getOffset | | int getOffset(Object o)(Code) | | Returns the offset for a visited object, or -1 if never visited.
|
| replaceObject | | void replaceObject(Object existing, Object replacement)(Code) | | Replaces a given object in the list. Used when an object is converted
after adding it to the list.
|
| setObject | | void setObject(int index, Object o)(Code) | | Sets the object for an existing slot index.
|
| setOffset | | void setOffset(int index, int offset)(Code) | | Sets the offset for an existing slot index.
