Abstract
One embodiment of the present invention provides a system that determines whether a data structure, such as an array, is modifiable. First, the system loads a source file for a class. The system then examines the source file to identify a set of data structures in the class, and uses escape analysis to determine whether each data structure is modifiable. The system then performs an action based on the determination. In a variation on this embodiment, if the data structure is not determined to be modifiable, performing the action involves storing the data structure in a read-only memory (ROM) instead of a random-access memory (RAM), which leaves more RAM available for other purposes.
