getKey

public java.lang.String getKey()

Description copied from interface: MediaEffect

Get the key for this effect.

Keys uniquely describe the implementation and function of the effect. The implementation key should come first, and the function key at the end. Some standard function key values are defined in this API: MediaEffect.KEY_SCALE for re-sizing and MediaEffect.KEY_ROTATE for rotating.

For example, a key might look like image.awt.rotate for an image rotation effect based on a Java AWT implementation.

Returns:

the effect key
