Class MetadataBuildingProcess

java.lang.Object

org.hibernate.boot.model.process.spi.MetadataBuildingProcess

public class MetadataBuildingProcess
extends Object

Represents the process of of transforming a MetadataSources reference into a Metadata reference. Allows for 2 different process paradigms:

• Single step : as defined by the build(org.hibernate.boot.MetadataSources, org.hibernate.boot.spi.BootstrapContext, org.hibernate.boot.spi.MetadataBuildingOptions) method; internally leverages the 2-step paradigm
• Two step : a first step coordinates resource scanning and some other preparation work; a second step builds the Metadata. A hugely important distinction in the need for the steps is that the first phase should strive to not load user entity/component classes so that we can still perform enhancement on them later. This approach caters to the 2-phase bootstrap we use in regards to WildFly Hibernate-JPA integration. The first step is defined by prepare(org.hibernate.boot.MetadataSources, org.hibernate.boot.spi.BootstrapContext) which returns a ManagedResources instance. The second step is defined by calling complete(org.hibernate.boot.model.process.spi.ManagedResources, org.hibernate.boot.spi.BootstrapContext, org.hibernate.boot.spi.MetadataBuildingOptions)
