Modifier and Type | Method and Description |
---|---|
void |
beforeInitialize(CollectionPersister persister,
int anticipatedSize)
Called before any elements are read into the collection,
allowing appropriate initializations to occur.
|
void |
beginRead()
Called just before reading any rows from the JDBC result set
|
Serializable |
disassemble(CollectionPersister persister)
Disassemble the collection to get it ready for the cache
|
Iterator |
elements()
Get an iterator over the array elements
|
boolean |
empty()
Is the collection empty? (don't try to initialize the collection)
|
boolean |
endRead()
Called after reading all rows from the JDBC result set
|
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 |
equalsSnapshot(CollectionPersister persister)

Object |
getArray() |
Iterator |
getDeletes(CollectionPersister persister,
boolean indexIsFormula)
Get all the elements that need deleting
|
Object |
getElement(Object entry)

Object |
getIndex(Object entry,
int i,
CollectionPersister persister)

|
Object |
getSnapshotElement(Object entry,
int i)
Get the snapshot value of the given collection entry
|
Object |
getValue()

|
void |
initializeFromCache(CollectionPersister persister,
Serializable disassembled,
Object owner)
Read the state of the collection from a disassembled cached value
|
boolean |
isDirectlyAccessible()
Could the application possibly have a direct reference to
the underlying collection implementation?
|
boolean |
isSnapshotEmpty(Serializable snapshot)
Is the snapshot empty?
|
boolean |
isWrapper(Object collection)
Is this the wrapper for the given collection instance?
|
boolean |
needsInserting(Object entry,
int i,
Type elemType)
Do we need to insert this element?
|
boolean |
needsUpdating(Object entry,
int i,
Type elemType)
Do we need to update this element?
|
Object |
readFrom(ResultSet rs,
CollectionPersister persister,
CollectionAliases descriptor,
Object owner)
Read a row from the JDBC result set
