PackageClasses

public PackageClasses(String classpath)
               throws IOException

Creates an instance with the specified class path. The class path is interpreted as a list of file names, separated by the File.pathSeparator character. Empty names are treated as the current directory, names ending in the File.separator character are treated as directories, and other names are treated as JAR files.

Parameters:

classpath - the class path

Throws:

IOException - if a problem occurs accessing files in the class path

Method Detail

main

public static void main(String[] args)
                 throws IOException

Prints the classes in a package in the class path to standard output using the default character encoding. If second argument is specified, it is used as the class path, otherwise the system class path is used.

Parameters:

args - the arguments

Throws:

IllegalArgumentException - if less than one or more than two arguments are provided

IOException - if an I/O error occurs

compute

public Set compute(String[] packages)
            throws IOException

Returns a set of the fully qualified names of classes in the specified packages, not including classes in subpackages of those packages.

Parameters:

packages - the packages

Returns:

the class names

Throws:

IOException - if a problem occurs accessing files in the class path

compute

public Set compute(String packAge)
            throws IOException

Throws:

IOException

compute

public Set compute(boolean recurse,
                   String[] packages)
            throws IOException

Returns a set of the fully qualified names of classes in the specified packages, optionally including classes in subpackages of those packages.

Parameters:

recurse - if true, find classes in subpackages of the specified packages

packages - the packages

Returns:

the class names

Throws:

IOException - if a problem occurs accessing files in the class path

compute

public Set compute(boolean recurse,
                   String packAge)
            throws IOException

Returns a set of the fully qualified names of classes in the specified packages, optionally including classes in subpackages of those packages.

Parameters:

recurse - if true, find classes in subpackages of the specified package

packAge - the package

Returns:

the class names

Throws:

IOException - if a problem occurs accessing files in the class path
