Interface TopCodeCache

All Known Implementing Classes:

DefaultTopCodeCache

public interface TopCodeCache

Code cache used to compile and cache code for single source instances.

Used to cache individual code layers on top of the LayeredEngine. This top code cache is typically what is used if running a script from the Grengine if the script is not part of static code layers or the top load mode is "current first" and the source in the static code layers has been modified since compilation. Each source gets its own independent bytecode class loader that does not see any code of the other source instances in the top code cache.

Since:

1.0

Method Summary

Modifier and Type	Method and Description
void	clear() clears the cache.
TopCodeCache	clone() creates a clone with the same cached bytecode.
ClassLoader	getParent() gets the parent class loader.
SingleSourceCode	getUpToDateCode(Source source) gets the code from the cache, recompiling the given source if it had been modified.
void	setParent(ClassLoader parent) sets the parent class loader and clears the cache.
