Lazy calculation

See:
Description

Interface Summary

Accumulator<In,Out>	Accumulator.
Calc<T>	Top interface for calculations.
CalcInvoke<T>	Calc0 is does a lazy calculation of a value, that does not have any dependencies.
CartesianIndex	Create indexes for the inputs to a Cartesian product.
IndexTransform<In,Out>	Transform that know what index in a sequence it is transforming. So it will take the same index from both the input and the output. It will do outSeq.get(index) = transform(inSeq.get(index),index).
LazyCalc<T>	Interface for calculations with a dirty and setup concept.

Class Summary

AdvanceWhile<E>	This causes the iterator to be advanced as long as the the condition is true.
BaseAccumulator<In,Out>	BaseAccumulator accumulator.
CartesianIndex2	CartesianIndex2 creates an accessing scheme for 2 NumberedStream, List or Array.

Package org.shapelogic.calculation Description

Lazy calculation

New library for functional programming style lazy calculation.

Dependency

• This package can depend on util.
• There is no dependency of any image processing code or any external libraries outside Java 6.
• This can be used in a Java application, just by adding shapelogic_.jar.

Declarative programming

Declarative programming in ShapeLogic is build on the following:

• Rule database that can access Java object using Scripting languages or JEXL
• Streams / lazy lists
• Lazy calculations
• Goal driven tasks
• Maybe later IoC
