Class IllegalImportCheck

Implemented Interfaces:
Configurable, Contextualizable

public class IllegalImportCheck
extends Check

Checks for imports from a set of illegal packages. By default, the check rejects all sun.* packages since programs that contain direct calls to the sun.* packages are not 100% Pure Java.

To reject other packages, set property illegalPkgs to a comma-separated list of the illegal packages.

An example of how to configure the check is:

 <module name="IllegalImport"/>
 

An example of how to configure the check so that it rejects packages java.io.* and java.sql.* is

 <module name="IllegalImport">
    <property name="illegalPkgs" value="java.io, java.sql"/>
 </module>

 Compatible with Java 1.5 source.
