Package org.hibernate.reactive.id.impl

Class TableReactiveIdentifierGenerator

  • All Implemented Interfaces:
    java.io.Serializable, org.hibernate.boot.model.relational.ExportableProducer, org.hibernate.generator.BeforeExecutionGenerator, org.hibernate.generator.Generator, org.hibernate.id.Configurable, org.hibernate.id.IdentifierGenerator, ReactiveIdentifierGenerator<java.lang.Long>
    Direct Known Subclasses:
    EmulatedSequenceReactiveIdentifierGenerator
    public class TableReactiveIdentifierGenerator
extends BlockingIdentifierGenerator
implements org.hibernate.id.IdentifierGenerator
    Support for JPA's TableGenerator. Persistence is managed via a table which may hold multiple rows distinguished by a "segment" column value.

    This implementation supports block allocation, but does not guarantee that generated identifiers are sequential.
