## Class TaskAdapter

- java.lang.Object
- - org.apache.tools.ant.ProjectComponent
  - - org.apache.tools.ant.Task
    - - org.apache.tools.ant.TaskAdapter

All Implemented Interfaces:
  java.lang.Cloneable, TypeAdapter

    public class TaskAdapter
    extends Task
    implements TypeAdapter

Uses introspection to "adapt" an arbitrary Bean which doesn't itself extend Task, but still contains an execute method and optionally a setProject method.

### Constructor Detail

#### TaskAdapter

    public TaskAdapter()

No-arg constructor for reflection.

#### TaskAdapter

    public TaskAdapter(java.lang.Object proxy)

Constructor for given proxy. So you could write easier code

     myTaskContainer.addTask(new TaskAdapter(myProxy));

Parameters:
  `proxy` - The object which Ant should use as task.

### Method Detail

#### checkTaskClass

    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.

Parameters:
  `taskClass` - Class to test for suitability. Must not be `null`.
  `project` - Project to log warnings/errors to. Must not be `null`.
See Also:
  `Project.checkTaskClass(Class)`

#### checkProxyClass

    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`
Parameters:
  `proxyClass` - the class to check.

#### execute

    public void execute()
                 throws BuildException

Executes the proxied task.

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

#### setProxy

    public void setProxy(java.lang.Object o)

Sets the target object to proxy for.

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

#### getProxy

    public java.lang.Object getProxy()

Returns the target object being proxied.

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