org.axonframework.modelling.entity.annotation.SingleEntityChildModelDefinition

All Implemented Interfaces:

EntityChildModelDefinition

public class SingleEntityChildModelDefinition
extends AbstractEntityChildModelDefinition

EntityChildModelDefinition that creates EntityChildMetamodel instances for child entities that are represented as a single entity (not iterable). It resolves the child type from the member's type and creates a SingleEntityChildMetamodel accordingly.

Before version 5.0.0, this class was known as the org.axonframework.modelling.command.inspection.AggregateMemberAnnotatedChildEntityDefinition. The class has been renamed to better fit the new entity modeling.

Since:

5.0.0

Method Details

isMemberTypeSupported

protected boolean isMemberTypeSupported(@Nonnull
 Class<?> memberType)

Description copied from class: AbstractEntityChildModelDefinition

Check if the given member type supports this definition. Returning true from this method implies that the AbstractEntityChildModelDefinition.getChildTypeFromMember(Member) and AbstractEntityChildModelDefinition.doCreate(Class, EntityMetamodel, String, EventTargetMatcher, CommandTargetResolver) methods will be called.

Specified by:

isMemberTypeSupported in class AbstractEntityChildModelDefinition

Parameters:

memberType - The type of the member to check.

Returns:

Should return true if the member type is supported, false otherwise.

getChildTypeFromMember

protected Class<?> getChildTypeFromMember(@Nonnull
 Member member)

Description copied from class: AbstractEntityChildModelDefinition

Returns the actual child type. If it needs to be retrieved from a generic, this method should do so. This is used to construct the child EntityMetamodel using the AnnotatedEntityMetamodelFactory supplied by the parent entity metamodel.

Specified by:

getChildTypeFromMember in class AbstractEntityChildModelDefinition

Parameters:

member - The member to retrieve the child type from.

Returns:

The child type.

doCreate

@Nonnull
protected <C,
P> EntityChildMetamodel<C,P> doCreate(@Nonnull
 Class<P> parentClass,
 @Nonnull
 EntityMetamodel<C> entityMetamodel,
 @Nonnull
 String fieldName,
 @Nonnull
 EventTargetMatcher<C> eventTargetMatcher,
 @Nonnull
 CommandTargetResolver<C> commandTargetResolver)

Description copied from class: AbstractEntityChildModelDefinition

Creates a new EntityChildMetamodel for the given parent class and child metamodel. This method will be called if the AbstractEntityChildModelDefinition.isMemberTypeSupported(Class) returns true for the given member type.

Specified by:

doCreate in class AbstractEntityChildModelDefinition

Type Parameters:

C - The type of the child entity.

P - The type of the parent entity.

Parameters:

parentClass - The class of the parent entity.

entityMetamodel - The EntityMetamodel to use for the child entity.

fieldName - The name of the field to use for the child entity. If the member is a field, this will be the field name. If it is a method, the supposed field name will be the method name without the "get", "set" or "is" prefix and starting with a lowercase character.

eventTargetMatcher - The EventTargetMatcher to use for the child entity.

commandTargetResolver - The CommandTargetResolver to use for the child entity.

Returns:

A new EntityChildMetamodel for the given parent class and child metamodel.
