Abstract: A method for decreasing a computer application's start-up time. In one aspect, the method comprises: creating a serialized representation of application objects in a runtime environment; building an object code file using the serialized representation; and providing the application to a new runtime environment. In another embodiment the method may include the steps of: compiling an application provided in a source language; initializing the application in a runtime environment; and creating a serialized representation of the application.

Abstract: Code for a program is received by a compiler (or other entity). The code includes an expression for a variable and a marker that specifies when the expressions should be evaluated during execution of the program. Example markers can indicate that an expression should be evaluated immediately, once or always. Additional functionality is provided to the code in order to evaluate the expression at the specified time during execution of the program. If the expression is to be evaluated always, then the expression will likely be dependent on a item that can change. Functionality is provided that evaluates the expression when the item changes so that the variable can be updated.
