Constructor Detail


public TaskAdapter()
No-arg constructor for reflection.


public TaskAdapter(java.lang.Object proxy)
Constructor for given proxy. So you could write easier code
 myTaskContainer.addTask( new TaskAdapter(myProxy) );

proxy - The object which Ant should use as task.
Method Detail


public static void checkTaskClass(java.lang.Class<?> taskClass,
                                  Project project)
Checks whether or not a class is suitable to be adapted by TaskAdapter. If the class is of type Dispatchable, the check is not performed because the method that will be executed will be determined only at runtime of the actual task and not during parse time. This only checks conditions which are additionally required for tasks adapted by TaskAdapter. Thus, this method should be called by Project.checkTaskClass. Throws a BuildException and logs as Project.MSG_ERR for conditions that will cause the task execution to fail. Logs other suspicious conditions with Project.MSG_WARN.

taskClass - Class to test for suitability. Must not be null.
project - Project to log warnings/errors to. Must not be null.

public void checkProxyClass(java.lang.Class<?> proxyClass)
Check if the proxy class is a valid class to use with this adapter. The class must have a public no-arg "execute()" method.

Specified by:
checkProxyClass in interface TypeAdapter
proxyClass - the class to check.


public void execute()
             throws BuildException
Executes the proxied task.

execute in class Task
BuildException - if the project could not be set or the method could not be executed.


public void setProxy(java.lang.Object o)
Sets the target object to proxy for.

Specified by:
setProxy in interface TypeAdapter
o - The target object. Must not be null.


public java.lang.Object getProxy()
Returns the target object being proxied.

Specified by:
getProxy in interface TypeAdapter
the target proxy object.
