System and method for determining whether an array is a read-only array

A computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for determining whether an array is read-only, the method comprising:

• loading a source file for a class;
• examining the source file to identify a set of arrays in the class;
• using escape analysis to determine that a at least one array in the set of arrays is read-only, wherein escape analysis comprises, when an array is passed to one or more other classes, analyzing the one or more other classes to determine when the array is modified in the one or more other classes, and determining when a class method modifies the array;
• and
• storing data associated with the read-only array in a read-only memory (ROM).

A computer system that determines whether an array is read-only, comprising:

• a processor;
• and
• a memory;
• wherein the computer system is configured to,
• load a source file for a class,
• examine the source file to identify a set of arrays in the class,
• use escape analysis to determine that a at least one array in the set of arrays is read-only, wherein escape analysis comprises, when an array is passed to one or more other classes, analyzing the one or more other classes to determine when the array is modified in the one or more other classes, and determining when a class method modifies the array, and
• store data associated with the read-only array in a read-only memory (ROM).
