Class Fileset

ClassFileSet

A classfileset is a specialised type of fileset which, given a set of "root" classes, will include all of the class files upon which the root classes depend. This is typically used to create a jar with all of therequired classes for a particular application.

classfilesets are typically used by reference. They are declared with an"id" value and this is then used as a reference where a normal filesetis expected.

This type requires the BCEL library.

Attributes

The class fileset support the following attributes in additionto those supported by the standard fileset:

Nested Elements

Root

When more than one root class is required, multiple nested <root> elementsmay be used

RootFileSet

A root fileset is used to add a set of root classes from a fileset. In this case the entries in the fileset are expected to be Java class files. The name of the Java class is determined by the relative location of the classfile in the fileset. So, the file org/apache/tools/ant/Project.class corresponds to the Java classorg.apache.tools.ant.Project.

Examples

<classfileset id="reqdClasses" dir="${classes.dir}">  <root classname="org.apache.tools.ant.Project"/></classfileset>

This example creates a fileset containing all the class files upon which the org.apache.tools.ant.Project class depends. This fileset could then be used to create a jar.

<jar destfile="minimal.jar">  <fileset refid="reqdClasses"/></jar>

<classfileset id="reqdClasses" dir="${classes.dir}">  <rootfileset dir="${classes.dir}" includes="org/apache/tools/ant/Project*.class"/></classfileset>

This example constructs the classfileset using all the class with names starting with Project in the org.apache.tools.ant package
