- Property Detail
  - hasId
    
    Returns whether the PersistentEntity has an id property. If this call returns true, getIdProperty() will return a non-null value.
    
    Returns:
  - hasVersion
    
    Returns whether the PersistentEntity has a version property. If this call returns true, getVersionProperty() will return a non-null value.
    
    Returns:
- Method Detail
  - getName
```
String getName()
```
    The entity name including any package prefix.
    
    Returns:
    must never return null
  - getPersistenceConstructor
```
PreferredConstructor<T,P> getPersistenceConstructor()
```
    Returns the PreferredConstructor to be used to instantiate objects of this PersistentEntity.
    
    Returns:
    null in case no suitable constructor for automatic construction can be found. This usually indicates that the instantiation of the object of tthat persistent entity is done through either a customer EntityInstantiator or handled by custom conversion mechanisms entirely.
  - isConstructorArgument
```
boolean isConstructorArgument(PersistentProperty<?> property)
```
    Returns whether the given PersistentProperty is referred to by a constructor argument of the PersistentEntity.
    
    Parameters:
    property -
    
    Returns:
    true if the given PersistentProperty is referred to by a constructor argument or false if not or null.
  - isIdProperty
```
boolean isIdProperty(PersistentProperty<?> property)
```
    Returns whether the given PersistentProperty is the id property of the entity.
    
    Parameters:
    property -
    
    Returns:
  - isVersionProperty
```
boolean isVersionProperty(PersistentProperty<?> property)
```
    Returns whether the given PersistentProperty is the version property of the entity.
    
    Parameters:
    property -
    
    Returns:
  - getIdProperty
```
P getIdProperty()
```
    Returns the id property of the PersistentEntity. Can be null in case this is an entity completely handled by a custom conversion.
    
    Returns:
    the id property of the PersistentEntity.
  - getVersionProperty
```
P getVersionProperty()
```
    Returns the version property of the PersistentEntity. Can be null in case no version property is available on the entity.
    
    Returns:
    the version property of the PersistentEntity.
  - getPersistentProperty
```
P getPersistentProperty(String name)
```
    Obtains a PersistentProperty instance by name.
    
    Parameters:
    name - The name of the property
    
    Returns:
    the PersistentProperty or null if it doesn't exist.
  - getPersistentProperty
```
P getPersistentProperty(Class<? extends Annotation> annotationType)
```
    Returns the property equipped with an annotation of the given type.
    
    Parameters:
    annotationType - must not be null.
    
    Returns:
    Since:
    
    1.8
  - hasIdProperty
```
boolean hasIdProperty()
```
    Returns whether the PersistentEntity has an id property. If this call returns true, getIdProperty() will return a non-null value.
    
    Returns:
  - hasVersionProperty
```
boolean hasVersionProperty()
```
    Returns whether the PersistentEntity has a version property. If this call returns true, getVersionProperty() will return a non-null value.
    
    Returns:
  - getType
```
Class<T> getType()
```
    Returns the resolved Java type of this entity.
    
    Returns:
    The underlying Java class for this entity
  - getTypeAlias
```
Object getTypeAlias()
```
    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.
    
    Returns:
  - getTypeInformation
```
TypeInformation<T> getTypeInformation()
```
    Returns the TypeInformation backing this PersistentEntity.
    
    Returns:
  - doWithProperties
```
void doWithProperties(PropertyHandler<P> handler)
```
    Applies the given PropertyHandler to all PersistentPropertys contained in this PersistentEntity.
    
    Parameters:
    handler - must not be null.
  - doWithProperties
```
void doWithProperties(SimplePropertyHandler handler)
```
  - doWithAssociations
```
void doWithAssociations(AssociationHandler<P> handler)
```
    Applies the given AssociationHandler to all Association contained in this PersistentEntity.
    
    Parameters:
    handler - must not be null.
  - doWithAssociations
```
void doWithAssociations(SimpleAssociationHandler handler)
```
  - findAnnotation
```
<A extends Annotation> A findAnnotation(Class<A> annotationType)
```
    Looks up the annotation of the given type on the PersistentEntity.
    
    Parameters:
    annotationType - must not be null.
    
    Returns:
    Since:
    
    1.8
