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. |

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, 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 |
dump()
|
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. |
void |
getEntityFormats(java.util.Collection<Format> entityFormats)
|
Format |
getFormat(java.lang.Class cls)
Get a format for a given class, creating it if it does not exist. |
Format |
getFormat(int formatId)
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()
|
void |
openExisting()
Increments the reference count for a catalog that is already open. |

public Format getFormat(java.lang.Class cls)
This method is called for top level entity instances by PersistEntityBinding. When a new entity subclass format is added we call Store.openSecondaryIndexes so that previously unknown secondary databases can be created, before storing the entity. We do this here while not holding a synchronization mutex, not in addNewFormat, to avoid deadlocks. openSecondaryIndexes synchronizes on the Store. [#15247]
