Method Detail

getInitVersion

public int getInitVersion(Format format,
                 boolean forReader)

Description copied from interface: Catalog

See above.

Specified by:

getInitVersion in interface Catalog

getFormat

public Format getFormat(int formatId,
               boolean expectStored)

Description copied from interface: Catalog

Returns a format for a given ID, or throws an exception. This method is used when reading an object from the byte array format.

Specified by:

getFormat in interface Catalog

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.

getFormat

public Format getFormat(java.lang.Class cls,
               boolean checkEntitySubclassIndexes)

Description copied from interface: Catalog

Returns a format for a given class, or throws an exception. This method is used when writing an object that was passed in by the user.

Specified by:

getFormat in interface Catalog

checkEntitySubclassIndexes - is true if we're expecting this format to be an entity subclass and therefore subclass secondary indexes should be opened.

getFormat

public Format getFormat(java.lang.String className)

Description copied from interface: Catalog

Returns a format by class name. Unlike #getFormat(Class), the format will not be created if it is not already known.

Specified by:

getFormat in interface Catalog

createFormat

public Format createFormat(java.lang.String clsName,
                  java.util.Map<java.lang.String,Format> newFormats)

Specified by:

createFormat in interface Catalog

createFormat

public Format createFormat(java.lang.Class type,
                  java.util.Map<java.lang.String,Format> newFormats)

Specified by:

PersistCatalog.createFormat(java.lang.String, java.util.Map<java.lang.String, com.sleepycat.persist.impl.Format>)

isRawAccess

public boolean isRawAccess()
