In computer science, object file or objectcode is an intermediate representation of code generated by a compiler after it processes a source code file.
An object file format is a computer file format used for the storage of objectcode and related data typically produced by a compiler or Assembler.
The design and/or choice of an object file format is a key part of overall system design; it affects the performance of the linker and thus programmer turnaround while developing, and if the format is used for executables, the design also affects the time programs take to begin running, and thus the responsiveness for users.

Larry Lessig proposes that objectcode be subject to copyright (as it is today), but only if the associated source code is put in escrow, to be released when the copyright expires (a requirement that does not exist today).
This code is translated by a compiler into a form called “bytecode” which, contrary to the Standard Scenario, is not objectcode, i.e.
The code is distributed in bytecode form, and it can be executed in one of two ways: by feeding it directly to an interpreter, or by having the consumer translate it into objectcode.
By convention, the object returned by this method should be independent of this object (which is being cloned).
Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies.
Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned.
CodeGuru: Writing Code Generators with the Code Document Object Model - Part 1(Site not responding. Last check: 2007-10-21)
When you create a code generator what you are doing is organizing codeobjects into a hierarchical graph much as you organize code into a hierarchical ordering of text and code constructs.
The key to writing a successful code generator then is to find and organize the CodeObjects that represent the code that you want to generate, regardless of the language you suspect it will be rendered in.
For example, if you write a code generator for a typed collection then you could pass in the type to collect and the code generator will write a flawless typed collection every time, assuming the generator is written correctly.

Where a rental offset is allowed to a tenant, the amount of the rental credit should be shown as a charge to this objectcode and the gross monthly rental shown as rental income.
Note: This objectcode was created in FY 2000-01 to record costs from that year forward of land and improvements (only) on parcels acquired prior to environmental clearance.
Only those costs of land and improvements coded with ObjectCode 083 and Federal Aid Eligible prefix code of “7” will be considered when determining eligible acquisition costs for credit (soft match) on a Federal-Aid project.
This attribute may be used to specify the location of the object's data, for instance image data for objects defining images, or more generally, a serialized form of an object which can be used to recreate it.
attribute is instantiated every time an element that refers to that object requires it to be rendered (e.g., a link that refers to it is activated, an object that refers to it is activated, etc.).
Image maps allow authors to specify regions of an image or object and assign a specific action to each region (e.g., retrieve a document, run a program, etc.) When the region is activated by the user, the action is executed.
The tag is used to insert an object (such as ActiveX components, applets, image maps, media players, and plug-ins) into an HTML document and to provide all of the neccessary information to implement and run the object.
For example, you can give the location and type of the executable code of the object, and the location and type of any associated data files.
This is a wise precaution for slow-loading objects and should be considered a courtesy to the user.
In addition to generating Data Access Objects (DAOs) for a data integration tier, FireStorm/DAO also generates related Java code that is required as part of the business tier.
You use Data Transfer Objects when you want to transfer multiple data elements over a tier - which is better than making multiple calls to remote objects' getter methods when you receive only a single pierce of data back each time (reducing application performance due to unnecessary network overhead).
When the client requests the enterprise bean for the business data, the enterprise bean can construct the Data Transfer Object, populate it with its attribute values, and pass it by value to the client.

Amazon.co.uk: Books: Design patterns : elements of reusable object-oriented software(Site not responding. Last check: 2007-10-21)
This book identifies some common program-design problems--such as adapting the interface of one object to that of another object or notifying an object of a change in another object's state--and explains the best ways (not always the obvious ways) that the authors know to solve them.
Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk.
You wouldn't think that 23 patterns would be enough, but once you become adept at recognizing patterns, you'll find that a large fraction of the patterns you use in practice are among these 23.

It is a testament to the importance of this book that in the ten years since it was published the design patterns community has not really agreed on any additional patterns beyond the 23 defined here--although many more have certainly been proposed.
This is not the book to read if you are new to Object Oriented Programming, but if you understand the principles of OOP and OOA then this is a great place to jump in at the deep end.
It is intrinsically difficult to guarantee creation of a single object of a certain type in a multi-threaded application.
