- Method Detail
  - waitForSpace
```
public static void waitForSpace(long limit,
                                long timeout)
```
    Waits for the specified amount of heap memory to be available.
    If a timeout is specified (> 0) then this method will throw if it cannot observe enough free memory in time.
    
    If the timeout is not specified (<= 0) then this method will wait at most 10 seconds and proceed anyway.
    
    In all cases, an operating space of 15% of the maximum heap space is reserved. So the requested memory is deducted from these 15%.
    
    Parameters:
    
    limit - the minimum amount of memory bytes while leaving 15% free heap space for normal operations
    
    timeout - the maximum ms to wait, or a default of 10 seconds if <= 0
    
    Throws:
    
    java.lang.IllegalStateException - if the amount of free heap memory cannot be acheived in time and a timeout has been set explicitly
  - export
```
public static Data export()
```
    Returns a data representation of this class at this point in time
