## com.sleepycat.persist.model
Class AnnotationModel

    java.lang.Object
      com.sleepycat.persist.model.EntityModel
          com.sleepycat.persist.model.AnnotationModel

    public class AnnotationModel

extends EntityModel

The default annotation-based entity model. An `AnnotationModel` is based on annotations that are specified for entity classes and their key fields.

`AnnotationModel` objects are thread-safe. Multiple threads may safely call the methods of a shared `AnnotationModel` object.

The set of persistent classes in the annotation model is the set of all classes with the `Persistent` or `Entity` annotation.

The annotations used to define persistent classes are: `Entity`, `Persistent`, `PrimaryKey`, `SecondaryKey` and `KeyField`. A good starting point is `Entity`.

Constructor Summary
`AnnotationModel()` Constructs a model for annotated entity classes.

Method Summary
`ClassMetadata` | `getClassMetadata(String className)` Returns the metadata for a given persistent class name, including proxy classes and entity classes.
`EntityMetadata` | `getEntityMetadata(String className)` Returns the metadata for a given entity class name.
`Set<String>` | `getKnownClasses()` Returns the names of all known persistent classes.
`Set<String>` | `getKnownSpecialClasses()` Returns the names of all known persistent enum and array classes that may be used to store persistent data.

Methods inherited from class com.sleepycat.persist.model.EntityModel

Constructor Detail

### AnnotationModel

    public AnnotationModel()

  Constructs a model for annotated entity classes.

Method Detail

### getKnownClasses

    public Set<String> getKnownClasses()

  Description copied from class: `EntityModel`
  Returns the names of all known persistent classes. A type becomes known when an instance of the type is stored for the first time or metadata or type information is queried for a specific class name.

  Specified by:
    `getKnownClasses` in class `EntityModel`
  Returns:
    an unmodifiable set of class names.

### getKnownSpecialClasses

    public Set<String> getKnownSpecialClasses()

  Description copied from class: `EntityModel`
  Returns the names of all known persistent enum and array classes that may be used to store persistent data. This differs from `EntityModel.getKnownClasses()`, which does not return enum and array classes because they have no metadata.

  Overrides:
    `getKnownSpecialClasses` in class `EntityModel`
  Returns:
    an unmodifiable set of enum and array class names.

### getEntityMetadata

    public EntityMetadata getEntityMetadata(String className)

  Description copied from class: `EntityModel`
  Returns the metadata for a given entity class name.

  Specified by:
    `getEntityMetadata` in class `EntityModel`
  Returns:
    the metadata or null if the class is not an entity class or does not exist.

### getClassMetadata

    public ClassMetadata getClassMetadata(String className)

  Description copied from class: `EntityModel`
  Returns the metadata for a given persistent class name, including proxy classes and entity classes.

  Specified by:
    `getClassMetadata` in class `EntityModel`
  Returns:
    the metadata or null if the class is not persistent or does not exist.
