- Property Detail
  - isId
    
    Returns whether the property is a potential identifier property of the owning PersistentEntity. This method is mainly used by PersistentEntity implementation to discover id property candidates on PersistentEntity creation you should rather call PersistentEntity.isIdProperty(PersistentProperty) to determine whether the current property is the id property of that PersistentEntity under consideration.
    
    Returns:
  - isVersion
    
    Returns whether the current property is a potential version property of the owning PersistentEntity. This method is mainly used by PersistentEntity implementation to discover version property candidates on PersistentEntity creation you should rather call PersistentEntity.isVersionProperty(PersistentProperty) to determine whether the current property is the version property of that PersistentEntity under consideration.
    
    Returns:
- Method Detail
  - getOwner
```
PersistentEntity<?,P> getOwner()
```
  - getName
```
String getName()
```
    The name of the property
    
    Returns:
    The property name
  - getType
```
Class<?> getType()
```
    The type of the property
    
    Returns:
    The property type
  - getTypeInformation
```
TypeInformation<?> getTypeInformation()
```
    Returns the TypeInformation of the property.
    
    Returns:
  - getPersistentEntityType
```
Iterable<? extends TypeInformation<?>> getPersistentEntityType()
```
    Returns the TypeInformation if the property references a PersistentEntity. Will return null in case it refers to a simple type. Will return Collection's component type or the Map's value type transparently.
    
    Returns:
  - getGetter
```
Method getGetter()
```
    Returns the getter method to access the property value if available. Might return null in case there is no getter method with a return type assignable to the actual property's type.
    
    Returns:
    the getter method to access the property value if available, otherwise null.
  - getSetter
```
Method getSetter()
```
    Returns the setter method to set a property value. Might return null in case there is no setter available.
  - getField
```
Field getField()
```
  - getSpelExpression
```
String getSpelExpression()
```
  - getAssociation
```
Association<P> getAssociation()
```
  - isEntity
```
boolean isEntity()
```
    Returns whether the type of the PersistentProperty is actually to be regarded as PersistentEntity in turn.
    
    Returns:
  - isIdProperty
```
boolean isIdProperty()
```
    Returns whether the property is a potential identifier property of the owning PersistentEntity. This method is mainly used by PersistentEntity implementation to discover id property candidates on PersistentEntity creation you should rather call PersistentEntity.isIdProperty(PersistentProperty) to determine whether the current property is the id property of that PersistentEntity under consideration.
    
    Returns:
  - isVersionProperty
```
boolean isVersionProperty()
```
    Returns whether the current property is a potential version property of the owning PersistentEntity. This method is mainly used by PersistentEntity implementation to discover version property candidates on PersistentEntity creation you should rather call PersistentEntity.isVersionProperty(PersistentProperty) to determine whether the current property is the version property of that PersistentEntity under consideration.
    
    Returns:
  - isCollectionLike
```
boolean isCollectionLike()
```
    Returns whether the property is a Collection, Iterable or an array.
    
    Returns:
  - isMap
```
boolean isMap()
```
    Returns whether the property is a Map.
    
    Returns:
  - isArray
```
boolean isArray()
```
    Returns whether the property is an array.
    
    Returns:
  - isTransient
```
boolean isTransient()
```
    Returns whether the property is transient.
    
    Returns:
  - shallBePersisted
```
boolean shallBePersisted()
```

```
boolean isAssociation()
```
    Returns whether the property is an Association.
    
    Returns:
  - getComponentType
```
Class<?> getComponentType()
```
    Returns the component type of the type if it is a Collection. Will return the type of the key if the property is a Map.
    
    Returns:
    the component type, the map's key type or null if neither Collection nor Map.
  - getRawType
```
Class<?> getRawType()
```
    Returns the raw type as it's pulled from from the reflected property.
    
    Returns:
    the raw type of the property.
  - getMapValueType
```
Class<?> getMapValueType()
```
    Returns the type of the values if the property is a Map.
    
    Returns:
    the map's value type or null if no Map
  - getActualType
```
Class<?> getActualType()
```
    Returns the actual type of the property. This will be the original property type if no generics were used, the component type for collection-like types and arrays as well as the value type for map properties.
    
    Returns:
