AgentBuilder.CircularityLock

All Known Implementing Classes:

AgentBuilder.CircularityLock.Default, AgentBuilder.CircularityLock.Global, AgentBuilder.CircularityLock.Inactive

Enclosing interface:

AgentBuilder
```
public static interface AgentBuilder.CircularityLock
```
A circularity lock is responsible for preventing that a ClassFileLocator is used recursively. This can happen when a class file transformation causes another class to be loaded. Without avoiding such circularities, a class loading is aborted by a ClassCircularityError which causes the class loading to fail.

- Method Detail
  - acquire
```
boolean acquire()
```
    Attempts to acquire a circularity lock.
    
    Returns:
    
    true if the lock was acquired successfully, false if it is already hold.
  - release
```
void release()
```
    Releases the circularity lock if it is currently acquired.
