      • elem

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

      • 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:
        java.lang.IllegalArgumentException - if the element is null.

    • Method Detail

      • 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 java.lang.Runnable

      • equals

        public boolean equals​(java.lang.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 java.lang.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 java.lang.Object

      • toString

        public java.lang.String toString()
        Returns the string representation of this request task's texture atlas element.
        Overrides:
        toString in class java.lang.Object
