All Implemented Interfaces:
  `CompilationUnit.IPrimaryClassNodeOperation`

    public class SecureASTCustomizer
    extends CompilationCustomizer

This customizer allows securing source code by controlling what code constructs are permitted. This is typically done when using Groovy for its scripting or domain specific language (DSL) features. For example, if you only want to allow arithmetic operations in a groovy shell, you can configure this customizer to restrict package imports, method calls and so on.

Most of the security customization options found in this class work with either allowed or disallowed lists. This means that, for a single option, you can set an allowed list OR a disallowed list, but not both. You can mix allowed/disallowed strategies for different options. For example, you can have an allowed import list and a disallowed tokens list.

The recommended way of securing shells is to use allowed lists because it is guaranteed that future features of the Groovy language won't be accidentally allowed unless explicitly added to the allowed list. Using disallowed lists, you can limit the features of the language constructs supported by your shell by opting out, but new language features are then implicitly also available and this may not be desirable. The implication is that you might need to update your configuration with each new release.

If neither an allowed list nor a disallowed list is set, then everything is permitted.

Combinations of import and star import constraints are authorized as long as you use the same type of list for both. For example, you may use an import allowed list and a star import allowed list together, but you cannot use an import allowed list with a star import disallowed list. Static imports are handled separately, meaning that disallowing an import does not prevent from allowing a static import.

Eventually, if the features provided here are not sufficient, you may implement custom AST filtering handlers, either implementing the `SecureASTCustomizer.StatementChecker` interface or `SecureASTCustomizer.ExpressionChecker` interface then register your handlers thanks to the `addExpressionCheckers(org.codehaus.groovy.control.customizers.SecureASTCustomizer.ExpressionChecker...)` and `addStatementCheckers(org.codehaus.groovy.control.customizers.SecureASTCustomizer.StatementChecker...)` methods.

Here is an example of usage. We will create a groovy classloader which only supports arithmetic operations and imports the `java.lang.Math` classes by default.

     final ImportCustomizer imports = new ImportCustomizer().addStaticStars('java.lang.Math') // add static import of java.lang.Math
         final SecureASTCustomizer secure = new SecureASTCustomizer()
         secure.with {
             closuresAllowed = false
             methodDefinitionAllowed = false

             allowedImports = []
             allowedStaticImports = []
             allowedStaticStarImports = ['java.lang.Math'] // only java.lang.Math is allowed

             allowedTokens = [
                     PLUS,
                     MINUS,
                     MULTIPLY,
                     DIVIDE,
                     MOD,
                     POWER,
                     PLUS_PLUS,
                     MINUS_MINUS,
                     COMPARE_EQUAL,
                     COMPARE_NOT_EQUAL,
                     COMPARE_LESS_THAN,
                     COMPARE_LESS_THAN_EQUAL,
                     COMPARE_GREATER_THAN,
                     COMPARE_GREATER_THAN_EQUAL,
             ].asImmutable()

             allowedConstantTypesClasses = [
                     Integer,
                     Float,
                     Long,
                     Double,
                     BigDecimal,
                     Integer.TYPE,
                     Long.TYPE,
                     Float.TYPE,
                     Double.TYPE
             ].asImmutable()

             allowedReceiversClasses = [
                     Math,
                     Integer,
                     Float,
                     Double,
                     Long,
                     BigDecimal
             ].asImmutable()
         }
         CompilerConfiguration config = new CompilerConfiguration()
         config.addCompilationCustomizers(imports, secure)

  - ### setDisallowedReceivers

    public void setDisallowedReceivers​(List<String> disallowedReceivers)
    Sets the list of classes which deny method calls. Please note that since Groovy is a dynamic language, and this class performs a static type check, it will be relatively simple to bypass any disallowed list unless the disallowed receivers list contains, at a minimum, Object, Script, GroovyShell, and Eval. Additionally, it is necessary to also have MethodPointerExpression in the disallowed expressions list for the disallowed receivers list to function as a security check.
    Parameters:
      `disallowedReceivers` - the list of refused classes, as fully qualified names

    public void setReceiversBlackList​(List<String> disallowedReceivers)
    Legacy alias for `setDisallowedReceivers(List)`
