Class SimpleCatalog

java.lang.Object

com.sleepycat.persist.impl.SimpleCatalog

public class SimpleCatalog
extends Object

A static catalog containing simple types only. Once created, this catalog is immutable. For bindings accessed by a PersistComparator during recovery, the SimpleCatalog provides formats for all simple types. To reduce redundant format objects, the SimpleCatalog's formats are copied when creating a regular PersistCatalog. This class also contains utility methods for dealing with primitives.

Method Detail

resolveClass

public static Class resolveClass(String className,
                                 ClassLoader loader)
                          throws ClassNotFoundException

Throws:

ClassNotFoundException

resolveKeyClass

public static Class resolveKeyClass(String className,
                                    ClassLoader loader)

keyClassName

public static String keyClassName(String className)

getInitVersion

public int getInitVersion(Format format,
                          boolean forReader)

See above.

getFormat

public Format getFormat(int formatId,
                        boolean expectStored)

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

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(Class cls,
                        boolean checkEntitySubclassIndexes)

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.

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(String className)

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

createFormat

public Format createFormat(String clsName,
                           Map<String,Format> newFormats)

See Also:

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

createFormat

public Format createFormat(Class type,
                           Map<String,Format> newFormats)

See Also:

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

isRawAccess

public boolean isRawAccess()

See Also:

PersistCatalog.isRawAccess()

convertRawObject

public Object convertRawObject(RawObject o,
                               IdentityHashMap converted)

See Also:

PersistCatalog.convertRawObject(com.sleepycat.persist.raw.RawObject, java.util.IdentityHashMap)

resolveClass

public Class resolveClass(String clsName)
                   throws ClassNotFoundException

Throws:

ClassNotFoundException

See Also:

PersistCatalog.resolveClass(java.lang.String)

resolveKeyClass

public Class resolveKeyClass(String clsName)

See Also:

PersistCatalog.resolveKeyClass(java.lang.String)

allowRegisterProxy

public static boolean allowRegisterProxy(Class type)
