Abstract: The present invention relates to systems and methods that facilitate dynamic programming language execution in a managed code environment. A class component is provided that declares an inheritance hierarchy for one or more tagged values associated with a dynamic programming language. During execution of the tagged values, a rules component mitigates user-defined types from inheriting or deriving properties from the tagged values in order to support a type safe runtime environment. A bifurcated class tree is provided that defines non-tagged type elements on one side of the tree and tagged type element values on an alternate branch of the tree. The rules component analyzes runtime extensions that help to prevent data from one component of the tree deriving or inheriting properties from another component of the tree. The runtime extensions include such aspects as cast class extensions, test class extensions, and conversion class extensions for converting data types from one class subtype to another.

Abstract: An aspect-oriented system includes a way to access both local and remote advice that is consistent with the modularity concerns of an aspect-oriented program. During compilation of the aspect-oriented program, a weaver determines whether advice referenced by an aspect is local or remote. If the advice is local, the weaver applies the local advice to the base program. If the advice is remote, the weaver generates remote invocation code that may include client stubs and server code to handle the marshalling and unmarshalling of parameters. Invocations to the client stub are then inserted into the join points of the base program. At run-time, the server name and number that has the remote aspect is determined. When the client stub is invoked, the remote advice on the specified server may be accessed. The result is an improved weaver that may generate code to access remote advice in a different JVM.

Abstract: A query caching system and method for enabling the caching of software object instances at the granularity of query level. A query component in a container can issue a query to retrieve a query result from a database within a scope of a transaction. The query result includes one or more instances of a class that represents one or more persisted data entries retrieved from the database. A cache management component retrieves the query result for the query in the cache when a query registration component finds out that another query matches the query in the query registry. If the class is expected to remain unchanged within the transaction, the class can be configured to be used concurrently by multiple users, using an optimistic concurrency strategy. The cached query result can be invalidated during the transaction, when any row in any table in the database associated with the cached query result, or a range of any data entry of the one or more persisted data entries in the query is updated or invalidated.

Abstract: A system and method for establishing associative relationships between properties of a contained object and corresponding parameters of a container application is disclosed herein.

Abstract: A system and method for controlling execution of an interpreted language. Statements of the interpreted language to be executed by a script engine are intercepted by a protection module and control is passed to a script helper module that is associated with the script engine. The script helper module establishes a secure communications channel with an authorization component and passes the statements and an authorization request to the authorization component. The authorization component sends a reply to the script helper module which either permits the script engine to execute the statement or cancels the attempted execution. When the script engine is loaded, a list is updated identifying the script engine. If a script helper module is not present for the loaded script engine, a boot-strap loader is called to load the script helper module. A special information block contains data as to the location of the interception points.

Abstract: One embodiment of the present invention provides a system that characterizes content in object code. During operation, the system receives the source code of a program. The system also receives one or more pieces of object code of the program, or creates one or more pieces of object code from the source code. Next, the system identifies a construct in the object code. The system then determines whether the construct is physically present in the source code. If the construct is not physically present, the system determines whether the construct is logically present in the source code, wherein a construct is logically present if it is required by the programming language. If so, the system sets a construct flag to indicate that the construct is “synthesized.” However, if not, the system sets the construct flag to indicate that the construct is “synthetic.” Finally, the construct flag is made available to a reflective API.

Abstract: According to a technique described herein, a binding document comprises one or more “<bind>” element instances. Each “<bind>” element instance indicates an association between (a) an SVG element instance and (b) a class. When a binding's name is passed to a “createFromTemplate( )” method, the method processes all of the “<bind>” element instances that are associated within that name. For each such “<bind>” element instance, the method (a) creates, in an SVG DOM tree, a clone of a node that corresponds to an SVG element instance indicated in that “<bind>” element instance, (b) instantiates an object that is an instance of a class that is indicated in that “<bind>” element instance, and (c) stores data that establishes a binding between the clone node and the object. Methods of the object can be invoked to affect and/or alter attributes of the clone node to which the object is bound.

Abstract: A technique for handling user-interface gestures in non-rectangular regions of a graphical user interface includes creating a class comprising an event handler for an onmouseover event and an event handler for an onmouseout event. The technique further includes adding each of a group of graphical elements to the class. Adding a graphical element to the class includes adding a reference to the graphical element to the class and attaching the event handlers to the graphical element. The technique then identifies a specific graphical element in the group that triggered an invocation of one of the event handlers. The technique then determines the closest border of the specific graphical element to the mouse pointer. In the event another graphical element in the group shares the closest border, the technique stops either the onmouseover or onmouseout event from propagating. A corresponding apparatus and computer program product are also disclosed.

Abstract: In the described embodiments, a computer constructs a dispatch data structure for a holder by first determining a set of member holders from which the holder inherits. The computer then constructs an “i-table” that includes holder addressor regions that each contains addressors for an associated set of members. Each of the holder addressor regions is associated with an i-table index. The computer next collects a set of identification numbers for the set of member holders and, from these, constructs an “m-table.” The size of the m-table is selected to perfectly hash the set of identification numbers by the m-table size. The computer then computes an m-table index for each of the set of identification numbers modulo the m-table size and uses the m-table index to populate the m-table. The computer next stores the i-table index in the m-table in accordance with the m-table index.
