CompilerConfiguration
public CompilerConfiguration(CompilerConfiguration configuration)
Copy constructor. Use this if you have a mostly correct configuration for your compilation but you want to make a some changes programmatically. An important reason to prefer this approach is that your code will most likely be forward compatible with future changes to this configuration API.An example of this copy constructor at work:
// In all likelihood there is already a configuration in your code's context // for you to copy, but for the sake of this example we'll use the global default. CompilerConfiguration myConfiguration = new CompilerConfiguration(CompilerConfiguration.DEFAULT); myConfiguration.setDebug(true);
- Parameters:
configuration
- The configuration to copy.
-
CompilerConfiguration
public CompilerConfiguration(Properties configuration) throws ConfigurationException
Sets the configuration flags/settings according to values from the suppliedProperties
instance or if not found, supplying a default value. Note that unlikeCompilerConfiguration()
, the "defaults" here do not in general include checking the settings inSystem.getProperties()
. If you want to set a few flags but keep Groovy's default configuration behavior then be sure to make your settings in aProperties
object that is backed bySystem.getProperties()
(which is done using this constructor). That might be done like this:
And you also have to contend with a possibleProperties myProperties = new Properties(System.getProperties()); myProperties.setProperty("groovy.output.debug", "true"); myConfiguration = new CompilerConfiguration(myProperties);
SecurityException
when getting the system properties (SeeSystem.getProperties()
). A safer approach would be to copy a defaultCompilerConfiguration
and make your changes there using the setter:
The following properties are referenced when setting the configuration:// In all likelihood there is already a configuration for you to copy, // but for the sake of this example we'll use the global default. CompilerConfiguration myConfiguration = new CompilerConfiguration(CompilerConfiguration.DEFAULT); myConfiguration.setDebug(true);

If you explicitly add a global AST transformation in your compilation process, for example using theASTTransformationCustomizer
or using aCompilationUnit.PrimaryClassNodeOperation
, then nothing will prevent the transformation from being loaded.- Parameters:
disabledGlobalASTTransformations
- a set of fully qualified class names of global AST transformations which should not be loaded.
