Method Detail

getPersistenceConstructor

public PreferredConstructor<T,P> getPersistenceConstructor()

Description copied from interface: PersistentEntity

Returns the PreferredConstructor to be used to instantiate objects of this PersistentEntity.

Specified by:

getPersistenceConstructor in interface PersistentEntity<T,P extends PersistentProperty<P>>

Returns:

null in case no suitable constructor for automatic construction can be found.

isConstructorArgument

public boolean isConstructorArgument(P property)

Description copied from interface: PersistentEntity

Returns whether the given PersistentProperty is referred to by a constructor argument of the PersistentEntity.

Specified by:

isConstructorArgument in interface PersistentEntity<T,P extends PersistentProperty<P>>

Returns:

true if the given PersistentProperty is referred to by a constructor argument or false if not or null.

getName

public java.lang.String getName()

Description copied from interface: PersistentEntity

The entity name including any package prefix

Specified by:

getName in interface PersistentEntity<T,P extends PersistentProperty<P>>

Returns:

must never return null

getIdProperty

public P getIdProperty()

Description copied from interface: PersistentEntity

Returns the id property of the PersistentEntity. Must never return null as a PersistentEntity instance must not be created if there is no id property.

Specified by:

getIdProperty in interface PersistentEntity<T,P extends PersistentProperty<P>>

Returns:

the id property of the PersistentEntity.

setIdProperty

public void setIdProperty(P property)

Description copied from interface: MutablePersistentEntity

Sets the id property for the entity.

Specified by:

setIdProperty in interface MutablePersistentEntity<T,P extends PersistentProperty<P>>

addPersistentProperty

public void addPersistentProperty(P property)

Description copied from interface: MutablePersistentEntity

Adds a PersistentProperty to the entity.

Specified by:

addPersistentProperty in interface MutablePersistentEntity<T,P extends PersistentProperty<P>>

addAssociation

public void addAssociation(Association<P> association)

Description copied from interface: MutablePersistentEntity

Adds an Association to the entity.

Specified by:

addAssociation in interface MutablePersistentEntity<T,P extends PersistentProperty<P>>

getPersistentProperty

public P getPersistentProperty(java.lang.String name)

Description copied from interface: PersistentEntity

Obtains a PersistentProperty instance by name.

Specified by:

getPersistentProperty in interface PersistentEntity<T,P extends PersistentProperty<P>>

Parameters:

name - The name of the property

Returns:

The PersistentProperty or null if it doesn't exist

getType

public java.lang.Class<T> getType()

Description copied from interface: PersistentEntity

Returns the resolved Java type of this entity.

Specified by:

getType in interface PersistentEntity<T,P extends PersistentProperty<P>>

Returns:

The underlying Java class for this entity

getTypeAlias

public java.lang.Object getTypeAlias()

Description copied from interface: PersistentEntity

Returns the alias to be used when storing type information. Might be null to indicate that there was no alias defined through the mapping metadata.

Specified by:

getTypeAlias in interface PersistentEntity<T,P extends PersistentProperty<P>>

Returns:

getTypeInformation

public TypeInformation<T> getTypeInformation()

Description copied from interface: PersistentEntity

Returns the TypeInformation backing this PersistentEntity.

Specified by:

getTypeInformation in interface PersistentEntity<T,P extends PersistentProperty<P>>

Returns:

doWithProperties

public void doWithProperties(PropertyHandler<P> handler)

Description copied from interface: PersistentEntity

Applies the given PropertyHandler to all PersistentPropertys contained in this PersistentEntity.

Specified by:

doWithProperties in interface PersistentEntity<T,P extends PersistentProperty<P>>

Parameters:

handler - must not be null.

doWithAssociations

public void doWithAssociations(AssociationHandler<P> handler)

Description copied from interface: PersistentEntity

Applies the given AssociationHandler to all Association contained in this PersistentEntity.

Specified by:

doWithAssociations in interface PersistentEntity<T,P extends PersistentProperty<P>>

Parameters:

handler - must not be null.

verify

public void verify()

Description copied from interface: MutablePersistentEntity

Callback method to trigger validation of the PersistentEntity. As MutablePersistentEntity is not immutable there might be some verification steps necessary after the object has reached is final state.

Specified by:

verify in interface MutablePersistentEntity<T,P extends PersistentProperty<P>>
