Creates a new catalog, opening the database and reading it from a given
catalog database if it already exists.
|
| Modifier and Type | Method and Description |

boolean |
close()
Decrements the reference count and closes the catalog DB when it reaches
zero.

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.

Get a format for a given class, creating it if it does not exist.
|

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.

getMutations()
Returns the current merged mutations.
|
EntityModel |
getResolvedModel()
Returns the model parameter, default model or stored model.
|

getSubclassMap()
Returns a map from format to a set of its superclass formats.
|
boolean |

void |
openExisting()
Increments the reference count for a catalog that is already open.
|
(package private) void |
useExistingFormat(Format oldFormat)
Installs an existing format when no evolution is needed, i.e, when the
new and old formats are identical.

Catalogpublic Format getFormat(java.lang.Class cls, boolean openEntitySubclassIndexes)
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]
