Notes
 

Represents the "Function" entry of the type 4 shading dictionary object.

It is an optional entry defined as part of the PDF 1.0 specification.

It contains an array which contains FunctionElements.

If you read the specification you will see that an array of one FunctionElement may be represented as a single FunctionElement rather than an array. However we always present this property as an array to simplify the interface. It is only if you add or remove items in the array, that the underlying representation will be changed.
