EmbeddedMapping

public EmbeddedMapping(@Nonnull
 Class<? super C> container,
 @Nonnull
 Class<T> embeddableClass,
 @Nonnull
 String name,
 @Nonnull
 MemberMapping<T>[] fields)

Creates an instance of a EmbeddedMapping record class.

Parameters:

container - the value for the container record component

embeddableClass - the value for the embeddableClass record component

name - the value for the name record component

fields - the value for the fields record component

Method Details

fields

@Nonnull
public MemberMapping<T>[] fields()

Returns the value of the fields record component.

Returns:

the value of the fields record component

of

@SafeVarargs
@Nonnull
public static <C,T> EmbeddedMapping<C,T> of(@Nonnull
 Class<? super C> container,
 @Nonnull
 Class<T> embeddableClass,
 @Nonnull
 String name,
 @Nonnull
 MemberMapping<T>... fields)

Construct a new instance.

Type Parameters:

C - The container type

T - The embeddable type

Parameters:

container - The Java class which declares the field holding the embedded object

embeddableClass - The embeddable class

name - The name of the field holding the embedded object

fields - Mappings for fields or properties of the entity

of

@SafeVarargs
public static <C,T> EmbeddedMapping<C,T> of(@Nonnull
 SingularAttribute<? super C, T> embedded,
 @Nonnull
 MemberMapping<T>... fields)

Construct a new instance.

Type Parameters:

C - The container type

T - The embeddable type

Parameters:

embedded - The metamodel object representing the embedded object

fields - Mappings for fields or properties of the entity

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

container

@Nonnull
public Class<? super C> container()

Returns the value of the container record component.

Returns:

the value of the container record component

embeddableClass

@Nonnull
public Class<T> embeddableClass()

Returns the value of the embeddableClass record component.

Returns:

the value of the embeddableClass record component

name

@Nonnull
public String name()

Returns the value of the name record component.

Returns:

the value of the name record component
