- Method Detail
  - allocate
```
Page allocate(int size,
              boolean thief,
              boolean victim,
              OffHeapStorageArea owner)
```
    Attempt to allocate a page of the given size.
    Allocations identified as thieves will if necessary 'steal' space from previous allocations identified as 'victims' in order to fulfill the allocation request. owner is the area from which the returned page can subsequently be stolen or recovered. This is most likely to be the calling instance.
    
    Parameters:
    
    size - size of page to allocate
    
    thief - true if the allocation can steal space from victims
    
    victim - true if the allocated page should be eligible for stealing
    
    owner - owner from which subsequent steal should occur
    
    Returns:
    
    an allocated page, or null in the case of failure
  - free
```
void free(Page page)
