# Interface: com.pnfsoftware.jeb.core.units.code.asm.decompiler.INativeObjectTracker

Tracker for native underlying objects used by the decompiler or referenced by decompiled items. When underlying native objects change, current decompilations may be invalidated \(they become "stale"\).

## Method: acquire
- parameter: `item`, type: `com.pnfsoftware.jeb.core.units.code.asm.items.INativeItem`
