ClosedPackages

abstract class ClosedPackages extends (String) ⇒ Boolean

Determines which packages are open or closed; that is, determines to which packages code - which is not yet known - can potentially be contributed to. In other words, a package is considered open, if a developer is allowed to define a new type within the package's namespace. If a developer cannot define a new type within the package's namespace, the package is considered closed.

An example for closed packages are the packages within the java.* namespace of the JRE. Additionally, with Java 9 packages defined in modules can be considered closed.

The set of open/closed packages may influence call-graph construction as well as other analyses.

The concrete set of open/closed packages is specified in OPAL's configuration file. The relevant configuration key is: org.opalj.br.analyses.cg.ClosedPackagesKey.

The concrete analysis which determines the open/closed packages is instantiated reflectively by ClosedPackagesKey. This facilitates the configuration of project specific closed packages. The class can be configured using the config key: org.opalj.br.analyses.cg.ClosedPackagesKey.analysis={ClosedPackagesAnalysis}

Note

The concept of open and closed packages - and the reason why it matters - is discussed in "Call Graph Construction for Java Libraries"
