Description

Interface Summary

Accumulator<In,Out>	Accumulator.
Calc0<Out>	Calc0 is basically a Closure with 0 inputs.
Calc1<In,Out>	Calc0 is basically a Closure with 1 input.
Calc2<In0,In1,Out>	Calc2 is basically a Closure with 2 inputs.
CalcInContext<K,V>	Some calculations rely on the context that it is going on in.
CalcIndex0<Out>	Calc0 is basically a Closure with 0 inputs, but one index.
CalcIndex1<In,Out>	Calc0 is basically a Closure with 1 input, but one index.
CalcIndex2<In0,In1,Out>	Calc2 is basically a Closure with 1 input, and one index.
CalcInvoke<T>	Calc0 is does a lazy calculation of a value, that does not have any dependencies.
CalcList<In,Out>	CalcList is basically a Closure with input as a List.
CalcValue<T>	Top interface for calculations.
CartesianIndex	Create indexes for the inputs to a Cartesian product.
ContextGettable<K,V>	ContextGettable has contexts and ability to do a get in them.
InContexts<K>	Deprecated.
IndexTransform<In,Out>	Deprecated.
IQueryCalc<K,V>	A very general interface for doing any kind of queries to lazy calculations and streams.
LazyCalc<T>	Interface for calculations with a dirty and setup concept.
RecursiveContext<K>	Interface for classes that live in the a context with parent contexts. It will start in the first context and work back when trying to find a binding.
SetupFlagged	To test if something has been setup.
Transformer<In,Out>	Deprecated.

Class Summary

AdvanceWhile<E>	This causes the iterator to be advanced as long as the the condition is true.
BaseAccumulator<In,Out>	BaseAccumulator accumulator.
BaseCalcInContext<K,V>	BaseCalcInContext normal base class for CalcInContext.
CalcComposition	Compose Calculations.
CalcFixed<T>	This is a calculation that is done.
CartesianIndex2	CartesianIndex2 creates an accessing scheme for 2 NumberedStream, List or Array.
CollectionCalc	Normal functional operations used on Java Collections.
NamedCalcFixed<T>	This is a calculation that is done and set in the root context.
QueryCalc<K,V>	A very general interface for doing any kind of queries to lazy calculations and streams.
RootMap	This is the RootContext where all the certain objects are stored.
SimpleRecursiveContext<K>	Simple implementation of a RecursiveContext. This could be a mix in class or just a test class.

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
