Abstract
Official abstract text for this publication.
A system and method for accessing closure variables from a lambda expression in certain program configurations, in which the closure variable is accessed while the closure function is active and the closure variable is within an active runtime frame stack corresponding to an instance of the closure function. In response to entering the closure function, a pointer to each closure variable is stored in a stack pointer table. Each reference to each closure variable from the lambda expression is handled by using the closure variable pointer to locate the closure variable on the runtime stack. Program code may be instrumented to insert invocations to helper functions at locations upon entering the closure function and at each reference to each closure variable from the lambda expression.
First claim
Opening claim text (preview).
What is claimed as new and desired to be protected by Letters Patent of the United States is: 1. A computer-based method of accessing a closure variable defined in a function of a computer program from a lambda expression that is invoked from a computer program location outside the function while an instance of the function is active, the closure variable stored in a frame on a runtime stack, the frame corresponding to the function instance, comprising: a) in response to entering…
