public class About extends java.lang.Object
This package contains a number of classes that assists by analyzing JARs and constructing bundles. The Analyzer class can be used to analyze an existing bundle and can create a manifest specification from proposed (wildcard) Export-Package, Bundle-Includes, and Import-Package headers. The Builder class can use the headers to construct a JAR from the classpath. The Verifier class can take an existing JAR and verify that all headers are correctly set. It will verify the syntax of the headers, match it against the proper contents, and verify imports and exports. A number of utility classes are available. Jar, provides an abstraction of a Jar file. It has constructors for creating a Jar from a stream, a directory, or a jar file. A Jar, keeps a collection Resource's. There are Resource implementations for File, from ZipFile, or from a stream (which copies the data). The Jar tries to minimize the work during build up so that it is cheap to use. The Resource's can be used to iterate over the names and later read the resources when needed. Clazz, provides a parser for the class files. This will be used to define the imports and exports. Headers are translated toParameter
that contains all headers (the order is maintained). The attribute of each header are maintained in anAttrs
. Each additional file in a header definition will have its own entry (only native code does not work this way). The ':' of directives is considered part of the name. This allows attributes and directives to be maintained in the Attributes map. An important aspect of the specification is to allow the use of wildcards. Wildcards select from a set and can decorate the entries with new attributes. This functionality is implemented in Instructions. Much of the information calculated is in packages. A package is identified by a PackageRef (and a type by a TypeRef). The namespace is maintained byDescriptors
, which here is owned byAnalyzer
. A special class,Packages
maintains the attributes that are found in the code. @version $Revision: 1.2 $
