Constructor Detail

### EntityMetadata

    public EntityMetadata(String className,
                          PrimaryKeyMetadata primaryKey,
                          Map<String,SecondaryKeyMetadata> secondaryKeys)

### getClassName

    public String getClassName()

  Returns the name of the entity class.

### getPrimaryKey

    public PrimaryKeyMetadata getPrimaryKey()

  Returns the primary key metadata for this entity. Note that the primary key field may be declared in this class or in a subclass. This metadata may be specified using the `PrimaryKey` annotation.

### getSecondaryKeys

    public Map<String,SecondaryKeyMetadata> getSecondaryKeys()

  Returns an unmodifiable map of key name to secondary key metadata, or an empty map if no secondary keys are defined for this entity. The returned map contains a mapping for each secondary key of this entity, including secondary keys declared in subclasses and superclasses. This metadata may be specified using `SecondaryKey` annotations.

### equals
