    • getAncestor

      public @Nullable MetaClass getAncestor()
      Description copied from interface: MetaClass
      Immediate ancestor of the object, or null if there is no one.
      Specified by:
      getAncestor in interface MetaClass

    • getAncestors

      public List<MetaClass> getAncestors()
      Description copied from interface: MetaClass
      All ancestors of the metaclass, in order going up from the immediate ancestor.
      Specified by:
      getAncestors in interface MetaClass

    • getDescendants

      public Collection<MetaClass> getDescendants()
      Description copied from interface: MetaClass
      All descendants of the metaclass, recursively. Order is undefined.
      Specified by:
      getDescendants in interface MetaClass

    • getSession

      public Session getSession()
      Specified by:
      getSession in interface MetaClass
      Returns:
      containing MetaModel instance. Null signifies a temporary metaclass, not associated with an entity class.

    • getJavaClass

      public <T> Class<T> getJavaClass()
      Specified by:
      getJavaClass in interface MetaClass
      Returns:
      corresponding Java class

    • getProperties

      public Collection<MetaProperty> getProperties()
      Specified by:
      getProperties in interface MetaClass
      Returns:
      collection of meta properties owned by this metaclass and all its ancestors.

    • getStore

      public Store getStore()
      Specified by:
      getStore in interface MetaClass
      Returns:
      store of this entity

    • setStore

      public void setStore(Store store)

    • findProperty

      public @Nullable MetaProperty findProperty(String name)
      Description copied from interface: MetaClass
      Get MetaProperty by its name.
      Specified by:
      findProperty in interface MetaClass
      Returns:
      MetaProperty instance, or null if no such property found

    • getProperty

      public MetaProperty getProperty(String name)
      Description copied from interface: MetaClass
      Get MetaProperty by its name.
      Specified by:
      getProperty in interface MetaClass
      Returns:
      MetaProperty instance. Throws exception if not found.

    • getPropertyPath

      public MetaPropertyPath getPropertyPath(String propertyPath)
      Description copied from interface: MetaClass
      Returns MetaPropertyPath object, representing path to the property from the current class Note that this method don't take into account extensions(e.g. Dynamic Attributes add-on) and it returns null in case of not static attributes(attributes from extension). For getting all attributes (including attributes from extensions) use MetadataTools.resolveMetaPropertyPath(MetaClass, String) or MetadataTools.resolveMetaPropertyPathOrNull(MetaClass, String) methods.
      Specified by:
      getPropertyPath in interface MetaClass
      Parameters:
      propertyPath - dot-separated string
      Returns:
      MetaPropertyPath instance, or null if the input parameter doesn't represent a valid path.

    • getOwnProperties

      public Collection<MetaProperty> getOwnProperties()
      Specified by:
      getOwnProperties in interface MetaClass
      Returns:
      collection of meta properties directly owned by this metaclass.

    • setJavaClass

      public void setJavaClass(Class<?> javaClass)

    • addAncestor

      public void addAncestor(MetaClass ancestorClass)

    • registerProperty

      public void registerProperty(MetaProperty metaProperty)

    • replaceProperties

      public void replaceProperties(Collection<MetaProperty> properties, Collection<MetaProperty> ownProperties)

      Parameters:
      ancestors - ancestor chain of the meta class
      descendants - descendant meta classes
