When implementing an interpreter, is it a good or bad to piggyback off the host language's garbage collector? -


Assume that you are implementing an interpreter for a GCED language for GCed language, which looks like a GCD That you will receive garbage collection for free, as long as you are very careful about your design.

Is this usually done? Are there good reasons to do this?

There are two different things in language and sequence: they are not really related to IMHO.

Therefore, if your current runtime already provides GC, then there should be a good reason to increase the runtime with other GCs. In the good old days when the memory allocation in the OS was slow and expensive, the app brought its heap managers, where the smaller part of the data is more efficient in handling. This was a reading to add another memory management to the current runtime (or OS). But if you are talking about Java, .NET - then they should be sufficient and efficient to work most.

However, you may want to create a proper interface / API for memory and object management. Work (and others), so that your language ("guest") runtime can be applied later on to another host runtime.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
