Class TupleSerialFactory

java.lang.Object
  extended by com.sleepycat.collections.TupleSerialFactory

public class TupleSerialFactory
extends Object

Creates stored collections having tuple keys and serialized entity values. The entity classes must be Serializable and must implement the MarshalledTupleKeyEntity interfaces. The key classes must either implement the MarshalledTupleEntry interface or be one of the Java primitive type classes. Underlying binding objects are created automatically.

public TupleSerialFactory(ClassCatalog catalog)
Creates a tuple-serial factory for given environment and class catalog.

Method Detail

getCatalog

public final ClassCatalog getCatalog()
Returns the class catalog associated with this factory.


newMap

public <K,V extends MarshalledTupleKeyEntity> StoredMap<K,V> newMap(Database db,
                                                                    Class<K> keyClass,
                                                                    Class<V> valueBaseClass,
                                                                    boolean writeAllowed)
Creates a map from a previously opened Database object.

Parameters:
db - the previously opened Database object.
keyClass - is the class used for map keys. It must implement the MarshalledTupleEntry interface or be one of the Java primitive type classes.
valueBaseClass - the base class of the entity values for this store. It must implement the MarshalledTupleKeyEntity interface.
writeAllowed - is true to create a read-write collection or false to create a read-only collection.

newSortedMap

public <K,V extends MarshalledTupleKeyEntity> StoredSortedMap<K,V> newSortedMap(Database db,
                                                                                Class<K> keyClass,
                                                                                Class<V> valueBaseClass,
                                                                                boolean writeAllowed)
Creates a sorted map from a previously opened Database object.

Parameters:
db - the previously opened Database object.
keyClass - is the class used for map keys. It must implement the MarshalledTupleEntry interface or be one of the Java primitive type classes.
valueBaseClass - the base class of the entity values for this store. It must implement the MarshalledTupleKeyEntity interface.
writeAllowed - is true to create a read-write collection or false to create a read-only collection.

getKeyCreator

public <V extends MarshalledTupleKeyEntity> TupleSerialMarshalledKeyCreator<V> getKeyCreator(Class<V> valueBaseClass,
                                                                                             String keyName)
Creates a SecondaryKeyCreator object for use in configuring a SecondaryDatabase. The returned object implements the SecondaryKeyCreator interface.

Parameters:
valueBaseClass - the base class of the entity values for this store. It must implement the MarshalledTupleKeyEntity interface.
keyName - is the key name passed to the MarshalledTupleKeyEntity.marshalSecondaryKey(java.lang.String, com.sleepycat.bind.tuple.TupleOutput) method to identify the secondary key.

getEntityBinding

public <V extends MarshalledTupleKeyEntity> TupleSerialMarshalledBinding<V> getEntityBinding(Class<V> baseClass)
