Computing Dictionary
 
 Definition: 

1. A function, f : A -> B, is injective or one-one, or is an injection, if and only if

        for all a,b in A, f(a) = f(b) => a = b.

I.e. no two different inputs give the same output (contrast many-to-one). This is sometimes called an embedding. Only injective functions have left inverses f' where f'(f(x)) = x, since if f were not an injection, there would be elements of B for which the value of f' was not unique. If an injective function is also a surjection then is it a bijection.

2. An injection function is one which takes objects of type T and returns objects of type C(T) where C is some type constructor. An example is

        f x = (x, 0).

The opposite of an injection function is a projection function which extracts a component of a constructed object, e.g.

        fst (x,y) = x.

We say that f injects its argument into the data type and fst projects it out.

 
Medical Dictionary
 
 Definition: Using a syringe and needle to push fluids or drugs into the body; often called a "shot". The needle is positioned into the tissue under the skin (subcutaneous), into a vein (intravenous), or into a muscle (intramuscular).
 
Dream Dictionary
 
 Definition: Dreaming that you are being injected for health reasons, suggests your need for healing behavior/ideas/attitudes. You need to develop yourself on a mental and spiritual level. Dreaming that someone is forcibly injecting you, represents your negative attitudes about a particular situation/person. It also indicates the influence of peer pressure working against you. You are recognizing that someone is forcing their negative and unwelcome views/values on you.
