Media that store digitized data and which can be easily removed and/or transported from one computer system to another. Examples of removable electronic media include CD-ROM, DVD-ROM, USB flash drives and external/portable hard drives.
default_settingsThis is an optional file. When Clink loads its settings, it first tries to load default values for settings from a default_settings file in either the profile directory or the binaries directory. Then it loads the clink_settings file from the profile directory.The default_settings file can be useful for portable installations or when sharing your favorite Clink configuration with friends.

default_inputrcThis is an optional file. When Clink loads the Readline Init File, it first tries to load default values from a default_inputrc file in either the profile directory or the binaries directory. Then it loads the .inputrc file.The default_inputrc file can be useful for portable installations or when sharing your favorite Clink configuration with friends.
Historically applications using Hibernate would have used its proprietary XML mapping file format for this purpose.With the coming of JPA, most of this information is now defined in a way that is portable across ORM/JPA providers using annotations (and/or standardized XML format).This chapter will focus on JPA mapping where possible.For Hibernate mapping features not supported by JPA we will prefer Hibernate extension annotations.
Section 2.1 The Entity Class of the JPA 2.1 specification defines its requirements for an entity class.Applications that wish to remain portable across JPA providers should adhere to these requirements.
When using property-based access, Hibernate uses the accessors for both reading and writing the entity state.Every other method that will be added to the entity (e.g. helper methods for synchronizing both ends of a bidirectional one-to-many association) will have to be marked with the @Transient annotation.
Both the Person and the Address have a mappedBy @OneToMany side, while the PersonAddress owns the person and the address @ManyToOne associations.Because this mapping is formed out of two bidirectional associations, the helper methods are even more relevant.
Hibernate provides an API for helping to isolate applications from the differences in the underlying physical transaction system in use.Based on the configured TransactionCoordinatorBuilder, Hibernate will simply do the right thing when this transaction API is used by the application.This allows your applications and components to be more portable move around into different environments.
Most applications using Hibernate need some form of contextual session, where a given session is in effect throughout the scope of a given context.However, across applications the definition of what constitutes a context is typically different; different contexts define different scopes to the notion of current.Applications using Hibernate prior to version 3.0 tended to utilize either home-grown ThreadLocal-based contextual sessions, helper classes such as HibernateUtil, or utilized third-party frameworks, such as Spring or Pico, which provided proxy/interception-based contextual sessions. 2ff7e9595c
