The texture atlas element associated with this request task. Specified during construction.

Constructor Detail

RequestTask

protected RequestTask(TextureAtlasElement elem)

Constructs a new request task with the specified texture atlas element, but otherwise does nothing. Calling the new request tasks run method causes this to retrieve and load the specified element's image source.

Parameters:

elem - the texture atlas element who's image source is retrieved and loaded.

Throws:

IllegalArgumentException - if the element is null.

Method Detail

equals

public boolean equals(Object o)

Indicates whether another request task is equivalent to this one. This tests equality using the texture atlas element source of each task.

Overrides:

equals in class Object

Parameters:

o - the object to test.

Returns:

true if the specified object is a RequestTask, and its texture atlas element is equivalent to this task's texture atlas element.

hashCode

public int hashCode()

Returns the hash code for this request task's texture atlas element.

Overrides:

hashCode in class Object

run

public void run()

Retrieves and loads the image source from this request task's texture atlas element, and notifies the element when the load completes. This does nothing if the current thread has been interrupted.

Specified by:

run in interface Runnable

toString

public String toString()

Returns the string representation of this request task's texture atlas element.

Overrides:

toString in class Object
