Default imports

By default scripts will have the following default imports:

• The script interface classpath
• The Script context classpath

It is possible to add custom default imports to the scripts in the ScriptWrapper interface.

Adding custom default imports

There are two ways to add custom default imports:

• The first one is to override the AbstractScriptWrapper.getCustomImports() method
• The second one is to call one of the following methods:
• ScriptWrapper.addImports(Set) to add the set of imports
• ScriptWrapper.addImports(String...) to add the array of imports
• ScriptWrapper.addImports(Class...) to add the array of class imports

The addImports(...) method accept both path for classes or for packages^[1]

There is a limitation for package import for Python script

. For example the following construct is valid:

   wrapper.addImports("java.util.List", "my.package.*"); 

Note that it is possible to clear the default import declarations previously set on a wrapper by ScriptWrapper.clearImports().

Examples

The two following examples add a default import for the java.util.List interface.

By Overriding

   ScriptWrapper<Script> wrapper = new GroovyScriptWrapper<Script>() {
     protected Set<lt;String> getCustomDefaultImports() {
       Set<String> set = new TreeSet<>();
       set.add("java.util.List");
       return set;
     }
   };

   Script Script = wrapper.getScript();
   File file = new File(<our script file>);
   wrapper.installScript(file);

By setting the imports declarations externally

   ScriptWrapper<Script> wrapper = new GroovyScriptWrapper<Script>() {
   };
   wrapper.addImports("java.util.List");

   Script Script = wrapper.getScript();
   File file = new File(<our script file>);
   wrapper.installScript(file);
