## com.sleepycat.collections
Class TupleSerialFactory

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

public class TupleSerialFactory
extends Object

Creates stored collections having tuple keys and serialized entity values. The entity classes must implement the java.io.Serializable and 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.

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

Method Summary
`ClassCatalog` | `getCatalog()` Returns the class catalog associated with this factory.
`TupleSerialMarshalledKeyCreator` | `getKeyCreator(Class valueBaseClass, String keyName)` Creates a `SecondaryKeyCreator` object for use in configuring a `SecondaryDatabase`.
`StoredMap` | `newMap(Database db, Class keyClass, Class valueBaseClass, boolean writeAllowed)` Creates a map from a previously opened Database object.
`StoredSortedMap` | `newSortedMap(Database db, Class keyClass, Class valueBaseClass, boolean writeAllowed)` Creates a sorted map from a previously opened Database object.

Constructor Detail

### TupleSerialFactory

    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 StoredMap newMap(Database db,
                            Class keyClass,
                            Class 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 StoredSortedMap newSortedMap(Database db,
                                        Class keyClass,
                                        Class 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 TupleSerialMarshalledKeyCreator getKeyCreator(Class 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.
