With CSharp expression generate CLR code for filtering, mapping of collections.
Edit by : INTRODUCTION
If you come from a C++ background, its likely you have a very compile-time
view of the world. Because a C++ compiler does all code generation when the code
is compiled, C++ programs are Static systems that are fully known at compile time.
The Common Language Runtime provides a new way of doing things. The compile-time
world still exists, but it is also possible to build dynamic systems where new code
is added by loading assemblies or even by writing custom code on the fly.
ABOUT RUN TIME CODE GENERATOR
This products provides very efficient way of handling user requests manipulating with
elements of collections. Request is just String with valid CSharp expression. Code generator
generate new class which Apply method returns result of calculation of this expression.
So it can be used as very fast query system which selects objects from the collection
according to user specified criteria (very small database engine).It can be also used
if you want to perform some user specified calculation for all members of the collection.
Collection can consists of just one element, in this case code generator can be used as
very fast calculator.
Certainly Dynamic Code generation makes sense only when expression once specified
will be executed multiple times or it will be applied to collection with large number
of members.
HOW TO USE
This product currently generates two kind of objects: collection filters and mappers.
Filter is used to select members of collection matching user supplied criteria.
Mapper is used to perform some calculation for all members of the collection and
Create new collection with results of such calculation.
Classes MapperGenerator and FilterGenerator are used to generate mappers and filters correspondently. you can free download Execution-Time Code generator for CSharp 1.01 now.
