Constructs a PersistentBag
|
Modifier and Type | Method and Description |
---|---|
void |
add(int i,
Object o) |
boolean |
add(Object object) |
boolean |
addAll(Collection values) |
boolean |
addAll(int i,
Collection c) |
void |
beforeInitialize(CollectionPersister persister,
int anticipatedSize)
Called before any elements are read into the collection,
allowing appropriate initializations to occur.
|
void |
clear() |
boolean |
contains(Object object) |
boolean |
containsAll(Collection c) |
Serializable |
disassemble(CollectionPersister persister)
Disassemble the collection to get it ready for the cache
|
boolean |
empty()
Is the collection empty? (don't try to initialize the collection)
|
Iterator |
entries(CollectionPersister persister)
Iterate all collection entries, during update of the database
|
boolean |
entryExists(Object entry,
int i)
Does the given element/entry exist in the collection?
|
boolean |
equals(Object obj)
Bag does not respect the collection API and do an
JVM instance comparison to do the equals.
|
boolean |
equalsSnapshot(CollectionPersister persister)
Does the current state exactly match the snapshot?
|
Object |
get(int i) |
Iterator |
getDeletes(CollectionPersister persister,
boolean indexIsFormula)
Get all the elements that need deleting
|
Object |
getElement(Object entry)
Get the value of the given collection entry.
|
Object |
getIndex(Object entry,
int i,
CollectionPersister persister)
Get the index of the given collection entry
|
Collection |
getOrphans(Serializable snapshot,
String entityName)
get all "orphaned" elements
|
Serializable |
getSnapshot(CollectionPersister persister)
Return a new snapshot of the current state of the collection
|
Object |
getSnapshotElement(Object entry,
int i)
Get the snapshot value of the given collection entry
|
int |
hashCode() |

void |
initializeFromCache(CollectionPersister persister,
Serializable disassembled,
Object owner)
Read the state of the collection from a disassembled cached value
|
boolean |
isEmpty() |
boolean |
isRowUpdatePossible()
Can each element in the collection be mapped unequivocally to a single row in the database? Generally
bags and sets are the only collections that cannot be.
|
boolean |
isSnapshotEmpty(Serializable snapshot)
Is the snapshot empty?
|
boolean |
isWrapper(Object collection)
Is this the wrapper for the given collection instance?

Do we need to insert this element?
|
boolean |
needsRecreate(CollectionPersister persister)
Do we need to completely recreate this collection when it changes?
|
boolean |
needsUpdating(Object entry,
int i,
Type elemType)
Do we need to update this element?
|
int |
occurrences(Object o)
Count how many times the given object occurs in the elements
|
