Hibernate ORM - hibernate-core 6.4.4.Final · org.hibernate.tuple.Tuplizer

A tuplizer defines the contract for things which know how to manage a particular representation of a piece of data, given that representation's RepresentationMode (the entity-mode essentially defining which representation).

If that given piece of data is thought of as a data structure, then a tuplizer is the thing which knows how to

create such a data structure appropriately
extract values from and inject values into such a data structure

For example, a given piece of data might be represented as a POJO class. Here, it's representation and entity-mode is POJO. Well a tuplizer for POJO entity-modes would know how to

create the data structure by calling the POJO's constructor
extract and inject values through getters/setter, or by direct field access, etc

getGetter	back to summary
public Getter getGetter(int i) Retrieve the getter for the specified property. Parameters i:int The property index. Returns:Getter The property getter.

getGetter

back to summary

public Getter getGetter(int i)

Retrieve the getter for the specified property.

Parameters

i:int: The property index.

Returns:Getter

The property getter.

getMappedClass	back to summary
public Class<?> getMappedClass() Return the pojo class managed by this tuplizer. Need to determine how to best handle this for the Tuplizers for EntityModes other than POJO. todo : be really nice to not have this here since it is essentially pojo specific... Returns:Class<?> The persistent class.

getMappedClass

back to summary

public Class<?> getMappedClass()

Return the pojo class managed by this tuplizer.

Need to determine how to best handle this for the Tuplizers for EntityModes other than POJO.

todo : be really nice to not have this here since it is essentially pojo specific...

Returns:Class<?>: The persistent class.

getPropertyValue	back to summary
public Object getPropertyValue(Object entity, int i) Extract the value of a particular property from the given entity. Parameters entity:Object The entity from which to extract the property value. i:int The index of the property for which to extract the value. Returns:Object The current value of the given property on the given entity.

getPropertyValue

back to summary

public Object getPropertyValue(Object entity, int i)

Extract the value of a particular property from the given entity.

Parameters

entity:Object: The entity from which to extract the property value.
i:int: The index of the property for which to extract the value.

Returns:Object

The current value of the given property on the given entity.
