    - #### setTransactional

          public StoreConfig setTransactional(boolean transactional)

      Sets the transactional configuration property. By default this property is false.

      This property is true to open all store indices for transactional access. True may not be specified if the environment is not also transactional.

      Parameters:
        `transactional` - whether the store is transactional.
      Returns:
        'this'.

        whether the store is transactional.

    - #### setReadOnly

          public StoreConfig setReadOnly(boolean readOnly)

      Sets the read-only configuration property. By default this property is false.

      This property is true to open all store indices for read-only access, or false to open them for read-write access. False may not be specified if the environment is read-only.

      Parameters:
        `readOnly` - whether the store is read-only.
      Returns:
        'this'.

    - #### setReadOnlyVoid

          public void setReadOnlyVoid(boolean readOnly)

      The void return setter for use by Bean editors.
      Parameters:
        `readOnly` - whether the store is read-only.

    - #### getReadOnly

          public boolean getReadOnly()

      Returns the read-only configuration property.
      Returns:
        whether the store is read-only.

    - #### setSecondaryBulkLoad

          public StoreConfig setSecondaryBulkLoad(boolean secondaryBulkLoad)

      Sets the bulk-load-secondaries configuration property. By default this property is false.

      This property is true to cause the initial creation of secondary indices to be performed as a bulk load. If this property is true and `EntityStore.getSecondaryIndex` has never been called for a secondary index, that secondary index will not be created or written as records are written to the primary index. In addition, if that secondary index defines a foreign key constraint, the constraint will not be enforced.

      The secondary index will be populated later when the `getSecondaryIndex` method is called for the first time for that index, or when the store is closed and re-opened with this property set to false and the primary index is obtained. In either case, the secondary index is populated by reading through the entire primary index and adding records to the secondary index as needed. While populating the secondary, foreign key constraints will be enforced and an exception is thrown if a constraint is violated.

      When loading a primary index along with secondary indexes from a large input data set, configuring a bulk load of the secondary indexes is sometimes more performant than updating the secondary indexes each time the primary index is updated. The absence of foreign key constraints during the load also provides more flexibility.

      Parameters:
        `secondaryBulkLoad` - whether bulk-load-secondaries is used.
      Returns:
        'this'.

    - #### setSecondaryBulkLoadVoid

          public void setSecondaryBulkLoadVoid(boolean secondaryBulkLoad)

      The void return setter for use by Bean editors.
      Parameters:
        `secondaryBulkLoad` - whether bulk-load-secondaries is used.

    - #### getSecondaryBulkLoad

          public boolean getSecondaryBulkLoad()

      Returns the bulk-load-secondaries configuration property.
      Returns:
        whether bulk-load-secondaries is used.

    - #### setModel

          public StoreConfig setModel(EntityModel model)

      Sets the entity model that defines entity classes and index keys.

      If null is specified or this method is not called, an `AnnotationModel` instance is used by default.

      Parameters:
        `model` - the EntityModel.
      Returns:
        'this'.

    - #### setModelVoid

          public void setModelVoid(EntityModel model)

      The void return setter for use by Bean editors.
      Parameters:
        `model` - the EntityModel.

    - #### getModel

          public EntityModel getModel()

      Returns the entity model that defines entity classes and index keys.
      Returns:
        the EntityModel.

    - #### setMutations

          public StoreConfig setMutations(Mutations mutations)

      Configures mutations for performing lazy evolution of stored instances. Existing mutations for this store are not cleared, so the mutations required are only those changes that have been made since the store was last opened. Some new mutations may override existing specifications, and some may be supplemental.

      If null is specified and the store already exists, the previously specified mutations are used. The mutations are stored persistently in serialized form.

      Mutations must be available to handle all changes to classes that are incompatible with the class definitions known to this store. See `Mutations` and `Class Evolution` for more information.

      If an incompatible class change has been made and mutations are not available for handling the change, `IncompatibleClassException` will be thrown when creating an `EntityStore`.

      Parameters:
        `mutations` - the Mutations.
      Returns:
        'this'.

    - #### setMutationsVoid

          public void setMutationsVoid(Mutations mutations)

      The void return setter for use by Bean editors.
      Parameters:
        `mutations` - the Mutations.

    - #### getMutations

          public Mutations getMutations()

      Returns the configured mutations for performing lazy evolution of stored instances.
      Returns:
        the Mutations.

    - #### setDatabaseNamer

          public StoreConfig setDatabaseNamer(DatabaseNamer databaseNamer)

      Specifies the object reponsible for naming of files and databases. By default this property is `DatabaseNamer.DEFAULT`.
      Parameters:

      Returns:
        'this'.
      Throws:
        `java.lang.NullPointerException` - if a null parameter value is passed.

    - #### setDatabaseNamerVoid

          public void setDatabaseNamerVoid(DatabaseNamer databaseNamer)

      The void return setter for use by Bean editors.
      Parameters:
