摘要： A variety of methods and apparatus for managing deactivation and deletion of objects and server processes are taught. According to some embodiments of the present invention, a thread of execution termed the reaper thread systematically cycles through a computer process deactivating and/or deleting objects based upon a variety of criteria. One suitable criterion for object deactivation is based upon the amount of time lapsed since a client has requested services of the object. According to the timeout criterion, the reaper thread determines the period of time since the last client requested services from the object, compares this to a timeout value which may be defined by any suitable entity, and proceeds with deactivation and/or deletion accordingly. Object deletion may have a separate criterion or be specifically requested by a client. A deletion flag may be set to indicate that object deletion is requested. When an object has deactivated, the reaper thread further determines if the deletion flag for this object is set, and, if so, further proceeds to perform an object deletion operation. In some embodiments, the reaper thread is further responsible to shutdown the server process under which the reaper thread is executing. As is well known to those skilled in the art of object oriented programming, a thread of execution is essentially a sequential flow of the point of execution through a computer process. One suitable criterion for server process shutdown would be related to the server process activity.

摘要： A Web document based GUI for use on a client computer that is networked with server computers. The GUI enables a user of the client computer to initiate specific operations that are performed on the client computer and that define a particular application. The GUI comprises GUI Web documents and a Web browser. Each GUI Web document is located at the client computer or one of the server computers and comprises one or more links and one or more applets. Each link provides a link to a corresponding GUI document when selected by the user with the client computer while being displayed on the client computer. Each respective applet generates, when executed on the client computer, an interactive image that is displayed on the client computer. The user can initiate a respective operation (i.e., one of the GUI's specific operations) by acting on the interactive image with the client computer to invoke the respective applet to perform the respective operation on the client computer. The Web browser runs on the client computer and, each time a displayed link of a displayed GUI Web document has been selected by the user with the client computer, loads in, if not already loaded, and displays on the client computer the corresponding GUI Web document. The Web browser displays the corresponding GUI web document by executing each of the one or more applets of the corresponding GUI Web document and displaying on the client computer the corresponding interactive image and by displaying on the client computer the one or more links of the corresponding GUI Web document. The Web browser comprises an editor that edits on the client computer certain GUI Web Documents by adding and/or removing applets and links from the certain GUI Web documents. In this way, the GUI can be customized.

摘要： A compiler requires normal exceptions that are throwable by a method to be either explicitly declared or else "caught" by appropriate exception handlers in the method to be compiled. This ensures that all normal exceptions thrown will be handled by a programmer specified exception handler. The compiler inspects all instructions in a specified method that throw exceptions and all instructions that invoke other methods, and determines whether each type of exception throwable by those instructions and invocable methods is (A) a serious exception (i.e., not a normal exception), (B) is caught by an enclosing exception handler, or (C) is explicitly declared in the method header of the specified method. If any throwable exception cannot be so categorized, that means the throwable exception is a normal exception that is not caught by an enclosing exception and is not explicitly declared in the method header, which means that the method to be compiled is not well formed. As a result, the compiler rejects the specified method, aborting compilation and generating an appropriate error message. The compiler determines the set of throwable exceptions in part by inspecting the methods that are invocable by the specified method for declarations of throwable exceptions. When initiating execution of the specified method, the program execution system inspects the method's declaration of throwable exceptions and blocks execution of the specified method unless exception handlers have been established for handling all the exceptions, if any, included in the declaration.
摘要翻译：一个编译器需要正常的异常，这些异常可以被一个方法抛出，要在被编译的方法中被明确声明或被适当的异常处理程序“捕获”。这样可以确保抛出的所有正常异常都将由程序员指定的异常处理程序处理。编译器检查指定方法中的所有指令，抛出异常和调用其他方法的所有指令，并确定这些指令和可调用方法可抛出的每种异常类型是否为（A）严重异常（即不是正常异常），（B）被封闭的异常处理程序捕获，或者（C）被明确地声明在指定方法的方法头中。如果任何可抛出的异常不能被分类，那意味着可抛出的异常是一个正常的异常，它不被封闭的异常所捕获，并且没有在方法头中被明确声明，这意味着要编译的方法形式不是很好。因此，编译器会拒绝指定的方法，中止编译并生成相应的错误消息。编译器通过检查通过指定的方法可调用的方法来确定可抛出异常的集合，以声明可抛出的异常。当启动指定方法的执行时，程序执行系统会检查方法的可抛出异常声明并阻止执行指定的方法，除非已经建立了异常处理程序来处理声明中包含的所有异常（如果有的话）。

摘要： A computer system and method edits a hierarchical document that has starttags and endtags and leaf contents between ones of the starttags and endtags. The computer system includes a memory, a user interface, and a hierarchical document editor. The memory stores a data structure representing the hierarchical document. The data structure includes an array of items and a corresponding index and a corresponding index offset for each of the items. Each of the items represents a corresponding one of the starttags, endtags, and leaf contents. The user interface displays the hierarchical document. It also issues commands for editing the hierarchical document. The hierarchical document editor edits the hierarchical document in response to the issued commands by traversing ones of the items in the data structure based on the indexes and index offsets of the traversed ones of the items.

摘要： In summary, the present invention is a multithreaded computer system having a memory that stores a plurality of objects and a plurality of procedures. Each object has a lock status of locked or unlocked, and includes a data pointer to a data structure. The system uses a first object locking procedure to service lock requests on objects that have never been locked as well as object that have not recently been locked, and uses a second object locking procedure to service lock requests on locked objects and object that have been recently locked. The first object locking procedure has instructions for changing a specified unlocked object's lock status to locked, for copying the data structure referenced by the data pointer to an enlarged data structure including a lock data subarray for storing lock data, and for updating the data pointer to point to the enlarged data structure. The second object locking procedure has instructions for updating a specified object's stored lock data. A lock data cleanup procedure, executed when the system's garbage collection procedure is executed, releases the lock data subarray of a specified object if the object has not been recently locked.

摘要： A system and method for establishing a peer-to-peer communication connection between computer programs from the same security domain, but executing in first and second computers, is disclosed. A first computer program, while executing in the first computer, sends a communication a message to the second computer, requesting a peer-to-peer communication connection. Upon receiving the message at said second computer, the second computer determines whether a second computer program meeting predefined criteria for establishing a peer-to-peer communication connection is executing in the second computer. If so, the second computer sends to the first computer a reply message accepting the request. After receipt of the reply message by the first computer, the requested peer-to-peer communication connection between the first and second computer programs is established. In a preferred embodiment, the predefined criteria for establishing a peer-to-peer communication connection is that the first and second computer programs be from the same server computer.
