  • Method Details

    • isAccessibleWithoutJoin

      public static boolean isAccessibleWithoutJoin(Association association, PersistentProperty persistentProperty)
      Check if the property is an association ID that can be accessed without join. In a case it's not an ID stored outside the associated table.
      Parameters:
      association - The association
      persistentProperty - The association's property
      Returns:
      true if can be accessed

    • traversePersistentProperties

      public static void traversePersistentProperties(PersistentProperty property, BiConsumer<List<Association>,PersistentProperty> consumer)
      Traverses properties that should be persisted.
      Parameters:
      property - The property to start traversing from
      consumer - The function to invoke on every property

    • traversePersistentProperties

      public static void traversePersistentProperties(PersistentEntity persistentEntity, BiConsumer<List<Association>,PersistentProperty> consumer)
      Traverses properties that should be persisted.
      Parameters:
      persistentEntity - The persistent entity
      consumer - The function to invoke on every property

    • traversePersistentProperties

      public static void traversePersistentProperties(PersistentEntity persistentEntity, boolean includeIdentity, boolean includeVersion, BiConsumer<List<Association>,PersistentProperty> consumer)
      Traverses properties that should be persisted.
      Parameters:
      persistentEntity - The persistent entity
      includeIdentity - Should be identifier included
      includeVersion - Should be version included
      consumer - The function to invoke on every property

    • countPersistentProperties

      public static int countPersistentProperties(PersistentProperty property)
      Count possible embedded properties.
      Parameters:
      property - The property
      Returns:
      the count

    • countPersistentProperties

      public static int countPersistentProperties(List<Association> associations, PersistentProperty property)
      Count possible embedded properties.
      Parameters:
      property - The property
      associations - The associations
      Returns:
      the count

    • traversePersistentProperties

      public static void traversePersistentProperties(List<Association> associations, PersistentProperty property, BiConsumer<List<Association>,PersistentProperty> consumerProperty)

    • traversePersistentProperties

      public static void traversePersistentProperties(PersistentPropertyPath propertyPath, BiConsumer<List<Association>,PersistentProperty> consumerProperty)

    • traverse

      public static void traverse(PersistentPropertyPath propertyPath, Consumer<PersistentPropertyPath> consumer)

    • traversePersistentProperties

      public static void traversePersistentProperties(PersistentPropertyPath propertyPath, boolean traverseEmbedded, BiConsumer<List<Association>,PersistentProperty> consumerProperty)

    • traversePersistentProperties

      public static void traversePersistentProperties(List<Association> associations, PersistentProperty property, boolean traverseEmbedded, BiConsumer<List<Association>,PersistentProperty> consumerProperty)

    • getPersistentPropertyPath

      public static Optional<String> getPersistentPropertyPath(PersistentEntity entity, String path)
      Computes a dot separated property path for the given camel case path.
      Parameters:
      path - The camel case path, can contain underscore to indicate how we should traverse entity properties
      entity - the persistent entity
      Returns:
      The dot separated version or null if it cannot be computed

    • isPropertyGenerated

      public static boolean isPropertyGenerated(PersistentEntity entity, PersistentProperty ownerProperty, PersistentProperty property)
      Checks whether a given property is considered generated based on its annotations and relationship with its owner property.
      Parameters:
      entity - the persistent entity that owns the property
      ownerProperty - the property that owns the given property. This means when we are doing traversal in case it is an association. If not an association then ownerProperty will be the same as property.
      property - the property to check
      Returns:
      true if the property is considered generated, false otherwise
