Core

Multi-targetingSide by Side in the

same processCode by Contract

*cough* Spec# *cough*

PC49TL02

public class ExampleClass {

public int ExampleMethod(int n)

{

CodeContract.Requires(n > 0,

"n must be greater than 0");

CodeContract.Ensures(

CodeContract.Result<int>() >= 0,

"Return value must be positive");

//...

}

public IEnumerable<String> Contents

{ get; set; }

[ContractInvariantMethod]

protected void ObjectInvariant() {

CodeContract.Invariant(

CodeContract.ForAll(Contents,

s => s != null));

//...

}

}

Contracts come at the

beginning of

methods.

Precondition

stating that the

input parameter to the

method must be greater than 0 for the

method to

function properly

.

Postcondition

guaranteeing

that the result of

the method will be

positive. Callers

can count

on this.

Developers can provide a string

to be displayed when

the contract

is violated

.

All object

invariants are

contained in a single

method, which

may contain many

calls to CodeContract.ObjectInvariant and no other calls.

Guarantees that

all elements in the

IEnumerable are

not null.

Parallel Programming Example
