All known Subclasses: org.apache.turbine.services.factory.TurbineFactoryService,
| FactoryService | | public interface FactoryService extends Service(Code) | | The Factory Service instantiates objects using either default
class loaders or a specified one. Whether specified class
loaders are supported for a class depends on implementation
and can be tested with the isLoaderSupported method.

| Field Summary | |
| String | SERVICE_NAME
The key under which this service is stored in TurbineServices. |
| Method Summary | |
| Object | getInstance(String className)
Gets an instance of a named class.
Parameters:
className - the name of the class. | | Object | getInstance(String className, ClassLoader loader)
Gets an instance of a named class using a specified class loader.
Class loaders are supported only if the isLoaderSupported
method returns true. | | Object | getInstance(String className, Object[] params, String[] signature)
Gets an instance of a named class.
Parameters for its constructor are given as an array of objects,
primitive types must be wrapped with a corresponding class.
Parameters:
className - the name of the class.
Parameters:
params - an array containing the parameters of the constructor.
Parameters:
signature - an array containing the signature of the constructor. | | Object | getInstance(String className, ClassLoader loader, Object[] params, String[] signature)
Gets an instance of a named class using a specified class loader.
Parameters for its constructor are given as an array of objects,
primitive types must be wrapped with a corresponding class.
Class loaders are supported only if the isLoaderSupported
method returns true. | | Class[] | getSignature(Class clazz, Object params, String signature)
Gets the signature classes for parameters of a method of a class.
Parameters:
clazz - the class.
Parameters:
params - an array containing the parameters of the method.
Parameters:
signature - an array containing the signature of the method. | | boolean | isLoaderSupported(String className)
Tests if specified class loaders are supported for a named class.
Parameters:
className - the name of the class. |
| SERVICE_NAME | | String SERVICE_NAME(Code) | | The key under which this service is stored in TurbineServices.
|
| getInstance | | Object getInstance(String className, ClassLoader loader) throws TurbineException(Code) | | Gets an instance of a named class using a specified class loader.
Class loaders are supported only if the isLoaderSupported
method returns true. Otherwise the loader parameter is ignored.
Parameters:
className - the name of the class.
Parameters:
loader - the class loader. the instance.
throws:
TurbineException - if instantiation fails. |
| getInstance | | Object getInstance(String className, Object[] params, String[] signature) throws TurbineException(Code) | | Gets an instance of a named class.
Parameters for its constructor are given as an array of objects,
primitive types must be wrapped with a corresponding class.
Parameters:
className - the name of the class.
Parameters:
params - an array containing the parameters of the constructor.
Parameters:
signature - an array containing the signature of the constructor. the instance.
throws:
TurbineException - if instantiation fails. |

Parameters:
className - the name of the class.
Parameters:
loader - the class loader.
Parameters:

| getSignature | | Class[] getSignature(Class clazz, Object params, String signature) throws ClassNotFoundException(Code) | | Gets the signature classes for parameters of a method of a class.
Parameters:
clazz - the class.
Parameters:
params - an array containing the parameters of the method.
Parameters:
signature - an array containing the signature of the method. an array of signature classes. Note that in some casesobjects in the parameter array can be switched to the contextof a different class loader.
throws:
ClassNotFoundException - if any of the classes is not found. |
| isLoaderSupported | | boolean isLoaderSupported(String className) throws TurbineException(Code) | | Tests if specified class loaders are supported for a named class.
Parameters:
className - the name of the class. true if class loaders are supported, false otherwise.
