ComponentType

Reconstruct the object from its cached "disassembled" state.

Perform a Comparator style comparison between values

Return a deep copy of the persistent state, stopping at entities and at collections.

Return a cacheable "disassembled" representation of the object.

Parse the XML representation of an instance.

Retrieve the cascade style of the indicated component property.

How many columns are used to persist this type. Always the same as sqlTypes(mapping).length

Retrieve the fetch mode of the indicated component property.

Get a hash code, consistent with persistence "equality". Again for most types the normal usage is to delegate to the value's #hashCode.

Returns the abbreviated name of the type.

Get the names of the component properties

Retrieve the indicators regarding which component properties are nullable.

An optional operation

Extract a particular component property value indicated by index.

Extract the values of the component properties from the given component instance

Extract the values of the component properties from the given component instance without access to the session.

An optional operation

The class returned by nullSafeGet(ResultSet, String, SessionImplementor, Object) methods. This is used to establish the class of an array of this type.

Get the types of the component properties

Retrieve an instance of the mapped class, or the identifier of an entity or collection, from a JDBC resultset. This is useful for 2-phase property initialization - the second phase is a call to resolveIdentifier().

This method does not populate the component parent

Return true if the implementation is castable to CompositeType. Essentially a polymorphic version of (type instanceof CompositeType.class). A component type may own collections or associations and hence must provide certain extra functionality.

Should the parent be considered dirty, given both the old and current value?

Should the parent be considered dirty, given both the old and current value?

Is this component embedded? "embedded" indicates that the component is "virtual", that its properties are "flattened" onto its owner

Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state).

This should always equate to some form of comparison of the value's internal state. As an example, for something like a date the comparison should be based on its internal "time" state based on the specific portion it is meant to represent (timestamp, date, time).

Is the given method a member of this component's class?

Has the value been modified compared to the current database state? The difference between this and the isDirty(Object, Object, boolean[], SessionImplementor) methods is that here we need to account for "partially" built values. This is really only an issue with association types. For most type implementations it is enough to simply delegate to isDirty(Object, Object, boolean[], SessionImplementor) here/

Are objects of this type mutable. (With respect to the referencing object ... entities and collections are considered immutable because they manage their own internal state.)

Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state) taking a shortcut for entity references.

For most types this should equate to #equals check on the values. For associations the implication is a bit different. For most types it is conceivable to simply delegate to isEqual(Object, Object, EntityMode)

Retrieve an instance of the mapped class from a JDBC resultset. Implementors should handle possibility of null values.

Retrieve an instance of the mapped class from a JDBC resultset. Implementations should handle possibility of null values. This method might be called if the type is known to be a single-column type.

Write an instance of the mapped class to a prepared statement. Implementors should handle possibility of null values. A multi-column type should be written to parameters starting from index.

Write an instance of the mapped class to a prepared statement, ignoring some columns. Implementors should handle possibility of null values. A multi-column type should be written to parameters starting from index.

During merge, replace the existing (target) value in the entity we are merging to with a new (original) value from the detached entity we are merging. For immutable objects, or null values, it is safe to simply return the first parameter. For mutable objects, it is safe to return a copy of the first parameter. For objects with component values, it might make sense to recursively replace component values.

Map identifiers to entities or collections. This is the second phase of 2-phase property initialization.

Given a hydrated, but unresolved value, return a value that may be used to reconstruct property-ref associations.

Inject property values onto the given component instance

An optional operation

A representation of the value to be embedded in an XML element.

Return the JDBC types codes (per java.sql.Types) for the columns mapped by this type.

Given an instance of the type, return an array of boolean, indicating which mapped columns would be null.

A representation of the value to be embedded in a log file.
