PersistCatalog(Transaction txn,
Environment env,
java.lang.String storePrefix,
java.lang.String dbName,
DatabaseConfig dbConfig,
EntityModel modelParam,
Mutations mutationsParam,
boolean rawAccess,
Store store)
Creates a new catalog, opening the database and reading it from a given catalog database if it already exists. |
Method Summary | |
---|---|
boolean |
close()
Decrements the reference count and closes the catalog DB when it reaches zero. |
java.lang.Object |
convertRawObject(RawObject o,
java.util.IdentityHashMap converted)
|
Format |
createFormat(java.lang.Class type,
java.util.Map<java.lang.String,Format> newFormats)
If the given class format is not already present in the given map and a format for this class name does not already exist, creates an uninitialized format, adds it to the map, and also collects related formats in the map. |
Format |
createFormat(java.lang.String clsName,
java.util.Map<java.lang.String,Format> newFormats)
Convenience method that gets the class for the given class name and calls createFormat with the class object. |
void |
flush()
Used to write the catalog when a format has been changed, for example, when Store.evolve has updated a Format's EvolveNeeded property. |
java.util.List<RawType> |
getAllRawTypes()
Returns all formats as RawTypes. |
java.lang.String |
getDatabaseClassName(java.lang.String className)
Returns the name of an entity class to be used to form the database name. |
java.lang.String |
getDatabaseKeyName(java.lang.String className,
java.lang.String keyName)
Similar to getDatabaseClassName but instead handles an earlier version of a renamed key. |
void |
getEntityFormats(java.util.Collection<Format> entityFormats)
|
Format |
getFormat(java.lang.Class cls,
boolean checkEntitySubclassIndexes)
Get a format for a given class, creating it if it does not exist. |
Format |
getFormat(int formatId,
boolean expectStored)
Returns a format for a given ID, or throws an exception. |
Format |
getFormat(java.lang.String className)
Returns a format by class name. |
int |
getInitVersion(Format format,
boolean forReader)
When a format is intialized, this method is called to get the version of the serialized object to be initialized. |
Format |
getLatestVersion(java.lang.String className)
|
Mutations |
getMutations()
Returns the current merged mutations. |
EntityModel |
getResolvedModel()
Returns the model parameter, default model or stored model. |
boolean |
isRawAccess()
|
boolean |
isReadOnly()
Returns true if the user opened the store read-only, or we're running in Replica upgrade mode. |
void |
openExisting()
Increments the reference count for a catalog that is already open. |

expectStored
- is true if reading a record from a database, and
therefore the format ID is expected to be stored also. If the format ID
is not stored, a RefreshException is thrown.public Format getFormat(java.lang.Class cls, boolean checkEntitySubclassIndexes)
This method is called for top level entity instances by PersistEntityBinding. When a new entity subclass format is added we call Store.checkEntitySubclassSecondaries to ensure that all secondary databases have been opened, before storing the entity. We do this here while not holding a synchronization mutex, not in addNewFormat, to avoid deadlocks. checkEntitySubclassSecondaries synchronizes on the Store. [#16399]
Historical note: At one time we opened / created the secondary databases rather than requiring the user to open them, see [#15247]. Later we found this to be problematic since a user txn may have locked primary records, see [#16399].
checkEntitySubclassIndexes
- is true if we're expecting this format
to be an entity subclass and therefore subclass secondary indexes should
be opened.public Format getFormat(java.lang.String className)
#getFormat(Class)
, the
format will not be created if it is not already known.
