Method Detail

getAssociatedClass

Class<?> getAssociatedClass()

getOps

<T> T getOps(Class<T> opsClass)

Operations may be associated with an entity. For example, an entity may support map operations (put, get, etc...) While such an entity may e.g. have a (read-only) size property, the get / put operations would be part of separate operations class associate with this entityOps instance.

findAnnotation

<A> A findAnnotation(Class<A> annotationClass)

isInstantiable

boolean isInstantiable()

newInstance

Object newInstance()

getProperties

Collection<? extends PropertyOps> getProperties()

isClonable

boolean isClonable()

clone

Object clone(Object Entity)

isPrimitive

boolean isPrimitive()

getEditableProperties

default Collection<? extends PropertyOps> getEditableProperties()

Convenience method for getting read- and writable properties

Returns:

getProperty

PropertyOps getProperty(String name)

getPropertyNames

default Set<String> getPropertyNames()

deepCopy

static Object deepCopy(Object entity,
                       java.util.function.Function<Class<?>,EntityOps> classToOps)

isCollection

boolean isCollection()

Entities may be container for items One issue is the identity of the items: E.g. a map is a collection of entry objects, but the getEntries method may create a copy of the entry objects. So if we cloned a collection, we would also have to clone the entry objects - even thought they are only temporary.

getItems

Iterator<?> getItems(Object entity)

setItems

void setItems(Object entity,
              Iterator<?> items)

deepCopy

static Object deepCopy(Object entity,
                       java.util.function.Function<Class<?>,EntityOps> classToOps,
                       Set<Object> managedEntities)

Deep copy, with any entity in managedEntities does NOT cause the creation of a clone For all entities not in the set a clone will be created and added to the set

Parameters:

entity -

classToOps -

managedEntities -

Returns:

deepCopy

static Object deepCopy(Object entity,
                       java.util.function.Function<Class<?>,EntityOps> classToOps,
                       java.util.function.Function<Object,Object> getEntityToClone,
                       java.util.function.BiConsumer<Object,Object> putEntityToClone)

deepCopy

static Object deepCopy(Object entity,
                       java.util.function.Function<Class<?>,EntityOps> classToOps,
                       java.util.function.Function<Object,Object> getEntityToClone,
                       java.util.function.BiConsumer<Object,Object> putEntityToClone,
                       java.util.function.Predicate<Object> getIsCopied,
                       java.util.function.Consumer<Object> setIsCopied)

copy

static void copy(EntityOps sourceOps,
                 EntityOps targetOps,
                 Object fromEntity,
                 Object toEntity)
