# Interface: com.pnfsoftware.jeb.core.units.code.java.IJavaMonitor

Java AST interface to represent a special "monitor" statement. It can be one of two types: 
 
- `__monitor_enter(lock)`
-  
- `__monitor_exit(lock)`
-  

 

 Such statements are not legal Java constructs. Combined with try\-finally blocks, they are used to represent very high\-level constructs known as `synchronized` blocks.
