What are the following constructs in Mono.Cecil referring to in C#?

[yeeen]

Can someone explain what are these referring to in Mono.Cecil?

TypeReference, ExternType, Override, NestedType, PInvokeInfo, SecurityDeclaration and CustomAttribute and MarshalSpec

Best if can illustrate with examples. Will appreciate even if u don't know all, but still help me in understanding those u know.

 

What is TerminateModuleDefinition doing in BaseReflectionVisitor? What is the use and how to call it?

I suggest you have a look at the ECMA-335 document. Cecil is basically
mapping the metadata layout that is decribed is the document into an
objet model.

The visitor pattern implemented in Cecil is kind of broken. I strongly
suggest you avoid using it, and implement your own visit mechanism. In
this particular case, it's just a method called after a module
definition has been completely visited.

But I realised there are a lot of Visitors inside Cecil...
Which do I use if I want to accomplish sth like
http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse.cdt.doc.isv/reference/api/org/eclipse/cdt/core/dom/ast/ASTVisitor.html
in eclipse?

If really there is no visitor pattern suitable for me...
Would implementing my own visitor without any existing visitor to extend be
difficult?

Can u tell me more specifically where should I look at? I search for
"metadata" but still can't find the info I want.
So I choose "PInvokeInfo" and try to search for it. I still can't it in the
file.

A reference to a type (which may be present within another assembly).

For example, if you compile the code:

        Console.WriteLine();

the IL will be:

        call void class [mscorlib]System.Console::WriteLine()

which in Mono.Cecil will be a MethodReference to
System.Console.WriteLine(), and MethodReference.DeclaringType will be a
TypeReference to System.Console.

>  ExternType, Override,

In this class:

        class Demo {
                public override string ToString() {return "demo";}
        }

The virtual method System.Object.ToString() is overridden.  All
overridden methods are present within an Overrides table for a type.

> NestedType,

A type declared within another type, e.g.:

        class List<T> {
                public struct Enumerator {}
        }

List<T>.Enumerator is a nested type.

>  PInvokeInfo,

When you use the [DllImport] attribute on a method.

>  SecurityDeclaration

Many System.Security attributes aren't saved as normal custom attributes
in IL, but instead are stored "specially".  Thus, there is a specific
table to store these "attributes".

(i.e. they only look like custom attributes within C# source, much like
[Serializable], but they're not really custom attributes.)

> and CustomAttribute

Used to store custom attributes:

        [AttributeUsage(AttributeTargets.All)]
        class FooAttribute : Attribute {
                public FooAttribute(string foo) {}
        }

        [Foo ("this is a custom attribute!")]
        class Bar {}

> and MarshalSpec

Used for custom marshaling.  Usually used only for P/Invoke marshaling.

Partition II ( Metadata definition and semantics); most notably
chapter 22 (Metadata logical format: tables). (That's from the 4th
edition from June 2006.)
