摘要： The present invention provides a programming model based on a relational view of the heap which defines identity declaratively, obviating the need for equals( ) and hashcode( ) methods. Each element in the heap (called a tuple) belongs to a relation type and relates an immutable identity to mutable state. The model entails a stricter contract: identity never changes during an execution. Objects, values, and singletons arise as special cases of tuples.
摘要翻译：本发明提供了一种基于堆的关系视图的编程模型，它以声明方式定义身份，避免了对equals（）和hashcode（）方法的需要。堆中的每个元素（称为元组）属于关系类型，并将不可变标识与可变状态相关联。该模型需要更严格的合同：执行期间身份永远不会改变。对象，值和单例出现为特殊情况的元组。

摘要： A system for associating a phase with an activation of a computer program that supports garbage collection include: a plurality of stacks, each stack including at least one stack frame that includes an activation count; and a processor with logic for performing steps of: zeroing the activation count whenever the program creates a new stack frame and after garbage collection is performed; determining whether an interval has transpired during program execution; examining each stack frame's content and incrementing the activation count for each frame of the stacks once the interval has transpired; detecting the phase whose activation count is non-zero and associating the phase with the activation; and ensuring that when the phase ends, an action is immediately performed.Detecting phases in a running computer program, creates an activation count associated with each stack frame. The activation count is zeroed whenever a new frame is created in a stack and incremented for each frame encountered during periodic intervals. A phase is detected with an activation whose activation count is non-zero.

摘要： A system and method for characterizing runtime behavior of a computer program executing in an execution environment, the method comprising: identifying one or more instances of yield points in a program to be executed, each yield point indicating a potential sampling operation during program execution; during program execution, in response to an identified yield point instance, ascertaining a state of the execution environment for indicating whether a sampling operation is to be performed; and, when the state of the execution environment indicates a sampling operation, recording relevant information for characterizing behavior of the execution environment. Relevant information for characterizing program behavior includes frequencies of methods executed in the program, and calling context associated with methods called by the program. Different mechanisms are provided for determining the sampling condition including the setting of a trigger bit by a runtime system, or, determining a sampling operations based on a fixed percentage of all executed yield points taken.
