Interface IJarBuilder

public interface IJarBuilder

A JAR builder can be used to add elements to a JAR file which is about to be build.

The protocol defined by this interface is:

• open is called
• addFile and addJar is called multiple times
• close is called

It is guaranteed that addFile and addJar is only called after open is called and before close is called. Other methods may be called any time.

Implementors must be prepared that an instance if the implementation is reused multiple times.

In order to provide backward compatibility for clients of IJarBuilder, extension interfaces are used to provide a means of evolution. The following extension interfaces exist:

• IJarBuilderExtension since version 3.5 introducing the following functions:
  • Write a file to the JAR to build

Since:

3.4
