ExponentialFunction
- All Implemented Interfaces:
Expression
,Function
Generate an output by interpolating between stops just less than and just greater than the function input. The domain
must be numeric.
Parameters:
- The interpolation input
- The base of the interpolation
- (...n) The remaining args are interpreted as pairs of stop values (input, output) for the interpolation. There must be an even number.

evaluate
Description copied from class:ExpressionAbstract
Default implementation delegates handling of context conversion to Converters utility class.Subclasses are expected to make use of the Converters utility class (as the easiest way to provide value morphing in conformance with the Filter specification).

- Type Parameters:
T
- The type of the returned object.- Parameters:
object
- The object to evaluate the expression against.context
- The type of the resulting value of the expression.- Returns:
- Evaluates the given expression based on the content of the given object an an instance of
