ptolemy.actor.lib.ArrayElement |
Extract an element from an array. This actor reads an array from the
input port and sends one of its elements to the output
port. The element that is extracted is determined by the
index parameter (or port). It is required that
0 <= index < N, where N is the
length of the input array, or
an exception will be thrown by the fire() method.

index
The index into the input array. This is an integer that
defaults to 0, and is required to be less than or equal to the
length of the input array. If the port is left unconnected,
then the parameter value will be used.
