Modifier and Type	Method	Description
boolean	canUseFor(ObjectIdGenerator<?> gen)	Method called to check whether this generator instance can be used for Object Ids of specific generator type and scope; determination is based by passing a configured "blueprint" (prototype) instance; from which the actual instances are created (using ObjectIdGenerator.newForSerialization(java.lang.Object)).
abstract T	generateId(Object forPojo)	Method used for generating a new Object Identifier to serialize for given POJO.

canUseFor

public boolean canUseFor(ObjectIdGenerator<?> gen)

Description copied from class: ObjectIdGenerator

Method called to check whether this generator instance can be used for Object Ids of specific generator type and scope; determination is based by passing a configured "blueprint" (prototype) instance; from which the actual instances are created (using ObjectIdGenerator.newForSerialization(java.lang.Object)).

True if this instance can be used as-is; false if not

generateId

public abstract T generateId(Object forPojo)

Description copied from class: ObjectIdGenerator

Method used for generating a new Object Identifier to serialize for given POJO.

Specified by:

generateId in class ObjectIdGenerator<T>

Parameters:

forPojo - POJO for which identifier is needed

Returns:

Object Identifier to use.
