Description copied from class: ObjectTranscriber.ArrayTranscriber

Stores a single element of an array.

Specified by:

storeElement in class ObjectTranscriber.ArrayTranscriber

Parameters:

value - An array of some type. The type of the array is conditional on the class which is implementing this method.
